We're dividing 4997813 by 641 
Our goal is to divide 4997813 by 641.

Going ahead to step 1:
4 divided by 641 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 641

Let's proceed to step 2:
641 can be fit into 49 0 times, resulting in a remainder of 49.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 49, we end up with 49.
Bring next digit (9) of the dividend behind the 49 and repeat the process: 499 / 641

Moving on to step 3:
The number 641 fits into 499 0 times, leaving a remainder of 499.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 499, we get 499.
Grab the next digit (7) from the dividend, add it to 499, then carry on: 4997 / 641

Advancing to step 4:
4997 divided by 641 is 7 with a remainder of 510.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 4487 away from 4997, we end up with 510.
Append the next digit (8) from the dividend to 510 and continue with: 5108 / 641

On to step 5:
641 goes into 5108 7 times with a remainder of 621.
Use 7 as the next digit of our solution. 
Result so far: 77.0
If we take 4487 away from 5108, we end up with 621.
Take the next digit (1) from the dividend and append it to 621, then repeat: 6211 / 641

Going ahead to step 6:
641 goes into 6211 9 times with a remainder of 442.
Record the quotient 9 as the next digit in the result. 
Result so far: 779.0
Deduct 5769 from 6211 and we're left with 442.
Grab the next digit (3) from the dividend, add it to 442, then carry on: 4423 / 641

Advancing to step 7:
The number 641 fits into 4423 6 times, leaving a remainder of 577.
The number 6 becomes the next digit in our result. 
Result so far: 7796.0
The remainder is 577 after subtracting 3846 from 4423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

Going ahead to step 8:
641 goes into 5770 9 times with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 7796.9
If we subtract 5769 from 5770, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
641 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 7796.9
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
641 goes into 100 0 times with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 7796.9
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 7796.9 with a remainder of 0.01.
