We're dividing 11157999 by 721 
We want to figure out the number of times 11157999 can be divided by 721.

Let's proceed to step 1:
The number 721 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 721

Moving on to step 2:
721 goes into 11 0 times with a remainder of 11.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 11 and we're left with 11.
Take the next digit (1) from the dividend and append it to 11, then repeat: 111 / 721

Step 3:
When dividing 111 by 721, we get 0 with a remainder of 111.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 111 leaves us with 111.
Fetch the next digit (5) from the dividend, attach it to 111 and continue: 1115 / 721

Step 4:
1115 divided by 721 is 1 with a remainder of 394.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 721 from 1115 leaves us with 394.
Include the next digit (7) from the dividend after 394, then repeat: 3947 / 721

Going ahead to step 5:
When dividing 3947 by 721, we get 5 with a remainder of 342.
The next digit of our result is 5. 
Result so far: 15.0
If we take 3605 away from 3947, we end up with 342.
Append the next digit (9) from the dividend to 342 and continue with: 3429 / 721

Advancing to step 6:
3429 divided by 721 is 4 with a remainder of 545.
Record the quotient 4 as the next digit in the result. 
Result so far: 154.0
Subtract 2884 from 3429 to get 545.
Append the next digit (9) from the dividend to 545 and continue with: 5459 / 721

Advancing to step 7:
721 can be fit into 5459 7 times, resulting in a remainder of 412.
Write down 7 as next digit of the result. 
Result so far: 1547.0
Subtracting 5047 from 5459 leaves us with 412.
Grab the next digit (9) from the dividend, add it to 412, then carry on: 4129 / 721

Going ahead to step 8:
When dividing 4129 by 721, we get 5 with a remainder of 524.
The number 5 becomes the next digit in our result. 
Result so far: 15475.0
The remainder is 524 after subtracting 3605 from 4129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Step 9:
721 goes into 5240 7 times with a remainder of 193.
The next digit of our result is 7. 
Result so far: 15475.7
Subtracting 5047 from 5240 leaves us with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Let's proceed to step 10:
The number 721 fits into 1930 2 times, leaving a remainder of 488.
Write down 2 as next digit of the result. 
Result so far: 15475.72
The remainder is 488 after subtracting 1442 from 1930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

On to step 11:
721 can be fit into 4880 6 times, resulting in a remainder of 554.
The number 6 becomes the next digit in our result. 
Result so far: 15475.726
If we subtract 4326 from 4880, we get 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Advancing to step 12:
721 can be fit into 5540 7 times, resulting in a remainder of 493.
The number 7 becomes the next digit in our result. 
Result so far: 15475.7267
Subtracting 5047 from 5540 leaves us with 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

Let's proceed to step 13:
If we divide 4930 by 721, we get 6 and a remainder of 604.
The next digit of our result is 6. 
Result so far: 15475.72676
Subtract 4326 from 4930 to get 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Advancing to step 14:
If we divide 6040 by 721, we get 8 and a remainder of 272.
Write down 8 as next digit of the result. 
Result so far: 15475.726768
Subtracting 5768 from 6040 leaves us with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Step 15:
The number 721 fits into 2720 3 times, leaving a remainder of 557.
Use 3 as the next digit of our solution. 
Result so far: 15475.7267683
If we subtract 2163 from 2720, we get 557.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5570, and continue the process.

Going ahead to step 16:
If we divide 5570 by 721, we get 7 and a remainder of 523.
The next digit of our result is 7. 
Result so far: 15475.72676837
Subtracting 5047 from 5570 leaves us with 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

The final outcome is 15475.72676837, with a leftover of 5.23e-07.
