We're dividing 21903391 by 691 
We're looking to find how many times 691 goes into 21903391.

Advancing to step 1:
691 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 691

Advancing to step 2:
If we divide 21 by 691, we get 0 and a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Bring next digit (9) of the dividend behind the 21 and repeat the process: 219 / 691

Advancing to step 3:
When dividing 219 by 691, we get 0 with a remainder of 219.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 219 and we're left with 219.
Fetch the next digit (0) from the dividend, attach it to 219 and continue: 2190 / 691

Going ahead to step 4:
2190 divided by 691 is 3 with a remainder of 117.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 2073 away from 2190, we end up with 117.
Append the next digit (3) from the dividend to 117 and continue with: 1173 / 691

On to step 5:
The number 691 fits into 1173 1 times, leaving a remainder of 482.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Subtracting 691 from 1173 leaves us with 482.
Take the next digit (3) from the dividend and append it to 482, then repeat: 4823 / 691

Advancing to step 6:
691 goes into 4823 6 times with a remainder of 677.
Put 6 as the next digit of the answer. 
Result so far: 316.0
Subtract 4146 from 4823 to get 677.
Include the next digit (9) from the dividend after 677, then repeat: 6779 / 691

Going ahead to step 7:
When dividing 6779 by 691, we get 9 with a remainder of 560.
The next digit of our result is 9. 
Result so far: 3169.0
If we take 6219 away from 6779, we end up with 560.
Bring next digit (1) of the dividend behind the 560 and repeat the process: 5601 / 691

Moving on to step 8:
691 goes into 5601 8 times with a remainder of 73.
Record the quotient 8 as the next digit in the result. 
Result so far: 31698.0
Subtract 5528 from 5601 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 9:
691 goes into 730 1 times with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 31698.1
If we subtract 691 from 730, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 10:
691 can be fit into 390 0 times, resulting in a remainder of 390.
Record the quotient 0 as the next digit in the result. 
Result so far: 31698.1
If we take 0 away from 390, we end up with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 11:
The number 691 fits into 3900 5 times, leaving a remainder of 445.
The next digit of our result is 5. 
Result so far: 31698.105
Deduct 3455 from 3900 and we're left with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

On to step 12:
691 goes into 4450 6 times with a remainder of 304.
The next digit of our result is 6. 
Result so far: 31698.1056
Subtract 4146 from 4450 to get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

On to step 13:
The number 691 fits into 3040 4 times, leaving a remainder of 276.
Record the quotient 4 as the next digit in the result. 
Result so far: 31698.10564
Deduct 2764 from 3040 and we're left with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Going ahead to step 14:
691 goes into 2760 3 times with a remainder of 687.
Put 3 as the next digit of the answer. 
Result so far: 31698.105643
If we subtract 2073 from 2760, we get 687.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6870, and continue the process.

Moving on to step 15:
691 goes into 6870 9 times with a remainder of 651.
The number 9 becomes the next digit in our result. 
Result so far: 31698.1056439
Deduct 6219 from 6870 and we're left with 651.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6510, and continue the process.

On to step 16:
If we divide 6510 by 691, we get 9 and a remainder of 291.
The next digit of our result is 9. 
Result so far: 31698.10564399
If we take 6219 away from 6510, we end up with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

The quotient of the division is 31698.10564399, and the remainder is 2.91e-07.
