We look at the division of 75605063 by 645 
We're looking to find how many times 645 goes into 75605063.

Advancing to step 1:
645 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 645

Let's proceed to step 2:
When dividing 75 by 645, we get 0 with a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 75 leaves us with 75.
Grab the next digit (6) from the dividend, add it to 75, then carry on: 756 / 645

Let's proceed to step 3:
756 divided by 645 is 1 with a remainder of 111.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 645 from 756 to get 111.
Grab the next digit (0) from the dividend, add it to 111, then carry on: 1110 / 645

Step 4:
When dividing 1110 by 645, we get 1 with a remainder of 465.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 645 away from 1110, we end up with 465.
Bring next digit (5) of the dividend behind the 465 and repeat the process: 4655 / 645

On to step 5:
When dividing 4655 by 645, we get 7 with a remainder of 140.
Use 7 as the next digit of our solution. 
Result so far: 117.0
The remainder is 140 after subtracting 4515 from 4655.
Bring next digit (0) of the dividend behind the 140 and repeat the process: 1400 / 645

Let's proceed to step 6:
645 goes into 1400 2 times with a remainder of 110.
The number 2 becomes the next digit in our result. 
Result so far: 1172.0
If we take 1290 away from 1400, we end up with 110.
Include the next digit (6) from the dividend after 110, then repeat: 1106 / 645

Moving on to step 7:
If we divide 1106 by 645, we get 1 and a remainder of 461.
The next digit of our result is 1. 
Result so far: 11721.0
If we take 645 away from 1106, we end up with 461.
Bring next digit (3) of the dividend behind the 461 and repeat the process: 4613 / 645

Step 8:
4613 divided by 645 is 7 with a remainder of 98.
Use 7 as the next digit of our solution. 
Result so far: 117217.0
If we take 4515 away from 4613, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Advancing to step 9:
The number 645 fits into 980 1 times, leaving a remainder of 335.
The number 1 becomes the next digit in our result. 
Result so far: 117217.1
If we take 645 away from 980, we end up with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Step 10:
645 goes into 3350 5 times with a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 117217.15
The remainder is 125 after subtracting 3225 from 3350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 11:
645 can be fit into 1250 1 times, resulting in a remainder of 605.
Record the quotient 1 as the next digit in the result. 
Result so far: 117217.151
Subtract 645 from 1250 to get 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

On to step 12:
When dividing 6050 by 645, we get 9 with a remainder of 245.
Record the quotient 9 as the next digit in the result. 
Result so far: 117217.1519
If we take 5805 away from 6050, we end up with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Let's proceed to step 13:
2450 divided by 645 is 3 with a remainder of 515.
Record the quotient 3 as the next digit in the result. 
Result so far: 117217.15193
Deduct 1935 from 2450 and we're left with 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Going ahead to step 14:
645 can be fit into 5150 7 times, resulting in a remainder of 635.
Put 7 as the next digit of the answer. 
Result so far: 117217.151937
The remainder is 635 after subtracting 4515 from 5150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

Step 15:
645 goes into 6350 9 times with a remainder of 545.
Write down 9 as next digit of the result. 
Result so far: 117217.1519379
If we take 5805 away from 6350, we end up with 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Going ahead to step 16:
645 goes into 5450 8 times with a remainder of 290.
Record the quotient 8 as the next digit in the result. 
Result so far: 117217.15193798
The remainder is 290 after subtracting 5160 from 5450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

The quotient of the division is 117217.15193798, and the remainder is 2.9e-07.
