84626544 divided by 645 
Let's see how many times 645 fits into 84626544.

Step 1:
When dividing 8 by 645, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 645

Advancing to step 2:
The number 645 fits into 84 0 times, leaving a remainder of 84.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Bring next digit (6) of the dividend behind the 84 and repeat the process: 846 / 645

Let's proceed to step 3:
The number 645 fits into 846 1 times, leaving a remainder of 201.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 645 from 846 to get 201.
Fetch the next digit (2) from the dividend, attach it to 201 and continue: 2012 / 645

Step 4:
645 goes into 2012 3 times with a remainder of 77.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we subtract 1935 from 2012, we get 77.
Append the next digit (6) from the dividend to 77 and continue with: 776 / 645

Let's proceed to step 5:
If we divide 776 by 645, we get 1 and a remainder of 131.
Record the quotient 1 as the next digit in the result. 
Result so far: 131.0
Subtracting 645 from 776 leaves us with 131.
Append the next digit (5) from the dividend to 131 and continue with: 1315 / 645

Step 6:
1315 divided by 645 is 2 with a remainder of 25.
Record the quotient 2 as the next digit in the result. 
Result so far: 1312.0
If we take 1290 away from 1315, we end up with 25.
Append the next digit (4) from the dividend to 25 and continue with: 254 / 645

On to step 7:
If we divide 254 by 645, we get 0 and a remainder of 254.
Write down 0 as next digit of the result. 
Result so far: 13120.0
Subtract 0 from 254 to get 254.
Take the next digit (4) from the dividend and append it to 254, then repeat: 2544 / 645

Step 8:
When dividing 2544 by 645, we get 3 with a remainder of 609.
Use 3 as the next digit of our solution. 
Result so far: 131203.0
Subtracting 1935 from 2544 leaves us with 609.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6090, and continue the process.

Going ahead to step 9:
When dividing 6090 by 645, we get 9 with a remainder of 285.
The number 9 becomes the next digit in our result. 
Result so far: 131203.9
If we take 5805 away from 6090, we end up with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Going ahead to step 10:
The number 645 fits into 2850 4 times, leaving a remainder of 270.
Use 4 as the next digit of our solution. 
Result so far: 131203.94
Deduct 2580 from 2850 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 11:
645 can be fit into 2700 4 times, resulting in a remainder of 120.
Record the quotient 4 as the next digit in the result. 
Result so far: 131203.944
Subtract 2580 from 2700 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

After the division, we end up with 131203.944 and a remainder of 0.012.
