49661246 divided by 645 
Let's see how many times 645 fits into 49661246.

Moving on to step 1:
If we divide 4 by 645, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 645

Moving on to step 2:
The number 645 fits into 49 0 times, leaving a remainder of 49.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 49, we get 49.
Fetch the next digit (6) from the dividend, attach it to 49 and continue: 496 / 645

On to step 3:
When dividing 496 by 645, we get 0 with a remainder of 496.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 496, we get 496.
Append the next digit (6) from the dividend to 496 and continue with: 4966 / 645

Let's proceed to step 4:
645 can be fit into 4966 7 times, resulting in a remainder of 451.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 451 after subtracting 4515 from 4966.
Grab the next digit (1) from the dividend, add it to 451, then carry on: 4511 / 645

Going ahead to step 5:
4511 divided by 645 is 6 with a remainder of 641.
Use 6 as the next digit of our solution. 
Result so far: 76.0
If we subtract 3870 from 4511, we get 641.
Grab the next digit (2) from the dividend, add it to 641, then carry on: 6412 / 645

Advancing to step 6:
645 goes into 6412 9 times with a remainder of 607.
The number 9 becomes the next digit in our result. 
Result so far: 769.0
If we subtract 5805 from 6412, we get 607.
Fetch the next digit (4) from the dividend, attach it to 607 and continue: 6074 / 645

On to step 7:
6074 divided by 645 is 9 with a remainder of 269.
Write down 9 as next digit of the result. 
Result so far: 7699.0
Subtracting 5805 from 6074 leaves us with 269.
Bring next digit (6) of the dividend behind the 269 and repeat the process: 2696 / 645

Going ahead to step 8:
645 goes into 2696 4 times with a remainder of 116.
Put 4 as the next digit of the answer. 
Result so far: 76994.0
If we take 2580 away from 2696, we end up with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 9:
The number 645 fits into 1160 1 times, leaving a remainder of 515.
The next digit of our result is 1. 
Result so far: 76994.1
Subtract 645 from 1160 to get 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Moving on to step 10:
645 can be fit into 5150 7 times, resulting in a remainder of 635.
Record the quotient 7 as the next digit in the result. 
Result so far: 76994.17
Deduct 4515 from 5150 and we're left with 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

Step 11:
645 can be fit into 6350 9 times, resulting in a remainder of 545.
The next digit of our result is 9. 
Result so far: 76994.179
Deduct 5805 from 6350 and we're left 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.

Moving on to step 12:
645 goes into 5450 8 times with a remainder of 290.
Write down 8 as next digit of the result. 
Result so far: 76994.1798
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.

On to step 13:
645 goes into 2900 4 times with a remainder of 320.
The number 4 becomes the next digit in our result. 
Result so far: 76994.17984
Subtract 2580 from 2900 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 14:
645 goes into 3200 4 times with a remainder of 620.
Use 4 as the next digit of our solution. 
Result so far: 76994.179844
If we subtract 2580 from 3200, we get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

The final outcome is 76994.179844, with a leftover of 6.2e-05.
