Let's divide 91156719 by 641
We want to figure out the number of times 91156719 can be divided by 641.

On to step 1:
641 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 641

On to step 2:
When dividing 91 by 641, we get 0 with a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Append the next digit (1) from the dividend to 91 and continue with: 911 / 641

Moving on to step 3:
When dividing 911 by 641, we get 1 with a remainder of 270.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 641 from 911 to get 270.
Fetch the next digit (5) from the dividend, attach it to 270 and continue: 2705 / 641

Advancing to step 4:
The number 641 fits into 2705 4 times, leaving a remainder of 141.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtracting 2564 from 2705 leaves us with 141.
Grab the next digit (6) from the dividend, add it to 141, then carry on: 1416 / 641

Moving on to step 5:
If we divide 1416 by 641, we get 2 and a remainder of 134.
Put 2 as the next digit of the answer. 
Result so far: 142.0
If we subtract 1282 from 1416, we get 134.
Grab the next digit (7) from the dividend, add it to 134, then carry on: 1347 / 641

On to step 6:
If we divide 1347 by 641, we get 2 and a remainder of 65.
Put 2 as the next digit of the answer. 
Result so far: 1422.0
If we subtract 1282 from 1347, we get 65.
Bring next digit (1) of the dividend behind the 65 and repeat the process: 651 / 641

Going ahead to step 7:
When dividing 651 by 641, we get 1 with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 14221.0
Deduct 641 from 651 and we're left with 10.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 641

Let's proceed to step 8:
The number 641 fits into 109 0 times, leaving a remainder of 109.
The number 0 becomes the next digit in our result. 
Result so far: 142210.0
If we subtract 0 from 109, we get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Going ahead to step 9:
1090 divided by 641 is 1 with a remainder of 449.
Write down 1 as next digit of the result. 
Result so far: 142210.1
Subtract 641 from 1090 to get 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Going ahead to step 10:
The number 641 fits into 4490 7 times, leaving a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 142210.17
The remainder is 3 after subtracting 4487 from 4490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 11:
641 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 142210.17
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
641 can be fit into 300 0 times, resulting in a remainder of 300.
Write down 0 as next digit of the result. 
Result so far: 142210.17
If we take 0 away from 300, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Our division results in 142210.17 with a remaining 0.003.
