We're dividing 15919276 by 691 
We want to figure out the number of times 15919276 can be divided by 691.

Let's proceed to step 1:
691 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 691

Going ahead to step 2:
The number 691 fits into 15 0 times, leaving a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 691

Let's proceed to step 3:
691 goes into 159 0 times with a remainder of 159.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 159, we end up with 159.
Fetch the next digit (1) from the dividend, attach it to 159 and continue: 1591 / 691

Advancing to step 4:
691 can be fit into 1591 2 times, resulting in a remainder of 209.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 1382 from 1591 and we're left with 209.
Fetch the next digit (9) from the dividend, attach it to 209 and continue: 2099 / 691

Moving on to step 5:
691 goes into 2099 3 times with a remainder of 26.
Use 3 as the next digit of our solution. 
Result so far: 23.0
The remainder is 26 after subtracting 2073 from 2099.
Grab the next digit (2) from the dividend, add it to 26, then carry on: 262 / 691

Let's proceed to step 6:
The number 691 fits into 262 0 times, leaving a remainder of 262.
Use 0 as the next digit of our solution. 
Result so far: 230.0
Subtract 0 from 262 to get 262.
Fetch the next digit (7) from the dividend, attach it to 262 and continue: 2627 / 691

Going ahead to step 7:
If we divide 2627 by 691, we get 3 and a remainder of 554.
The next digit of our result is 3. 
Result so far: 2303.0
If we take 2073 away from 2627, we end up with 554.
Fetch the next digit (6) from the dividend, attach it to 554 and continue: 5546 / 691

On to step 8:
691 can be fit into 5546 8 times, resulting in a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 23038.0
Deduct 5528 from 5546 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 9:
The number 691 fits into 180 0 times, leaving a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 23038.0
The remainder is 180 after subtracting 0 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 10:
1800 divided by 691 is 2 with a remainder of 418.
The next digit of our result is 2. 
Result so far: 23038.02
If we take 1382 away from 1800, we end up with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Let's proceed to step 11:
When dividing 4180 by 691, we get 6 with a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 23038.026
If we take 4146 away from 4180, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 12:
When dividing 340 by 691, we get 0 with a remainder of 340.
Use 0 as the next digit of our solution. 
Result so far: 23038.026
The remainder is 340 after subtracting 0 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 13:
3400 divided by 691 is 4 with a remainder of 636.
Put 4 as the next digit of the answer. 
Result so far: 23038.02604
Subtract 2764 from 3400 to get 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Step 14:
6360 divided by 691 is 9 with a remainder of 141.
Put 9 as the next digit of the answer. 
Result so far: 23038.026049
Subtract 6219 from 6360 to get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Step 15:
691 can be fit into 1410 2 times, resulting in a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 23038.0260492
If we take 1382 away from 1410, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 16:
The number 691 fits into 280 0 times, leaving a remainder of 280.
Write down 0 as next digit of the result. 
Result so far: 23038.0260492
Subtracting 0 from 280 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The final outcome is 23038.0260492, with a leftover of 2.8e-07.
