40491412 ÷ 691 
We want to divide 40491412 by 691.

On to step 1:
If we divide 4 by 691, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 691

Advancing to step 2:
40 divided by 691 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Grab the next digit (4) from the dividend, add it to 40, then carry on: 404 / 691

Advancing to step 3:
404 divided by 691 is 0 with a remainder of 404.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 404 to get 404.
Fetch the next digit (9) from the dividend, attach it to 404 and continue: 4049 / 691

Advancing to step 4:
691 can be fit into 4049 5 times, resulting in a remainder of 594.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 594 after subtracting 3455 from 4049.
Take the next digit (1) from the dividend and append it to 594, then repeat: 5941 / 691

Going ahead to step 5:
If we divide 5941 by 691, we get 8 and a remainder of 413.
The number 8 becomes the next digit in our result. 
Result so far: 58.0
Deduct 5528 from 5941 and we're left with 413.
Include the next digit (4) from the dividend after 413, then repeat: 4134 / 691

Let's proceed to step 6:
The number 691 fits into 4134 5 times, leaving a remainder of 679.
Write down 5 as next digit of the result. 
Result so far: 585.0
If we take 3455 away from 4134, we end up with 679.
Grab the next digit (1) from the dividend, add it to 679, then carry on: 6791 / 691

On to step 7:
When dividing 6791 by 691, we get 9 with a remainder of 572.
Use 9 as the next digit of our solution. 
Result so far: 5859.0
Deduct 6219 from 6791 and we're left with 572.
Grab the next digit (2) from the dividend, add it to 572, then carry on: 5722 / 691

Moving on to step 8:
691 goes into 5722 8 times with a remainder of 194.
Put 8 as the next digit of the answer. 
Result so far: 58598.0
If we subtract 5528 from 5722, we get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Moving on to step 9:
If we divide 1940 by 691, we get 2 and a remainder of 558.
Put 2 as the next digit of the answer. 
Result so far: 58598.2
The remainder is 558 after subtracting 1382 from 1940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

On to step 10:
5580 divided by 691 is 8 with a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 58598.28
Subtracting 5528 from 5580 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 11:
520 divided by 691 is 0 with a remainder of 520.
The number 0 becomes the next digit in our result. 
Result so far: 58598.28
If we subtract 0 from 520, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Advancing to step 12:
If we divide 5200 by 691, we get 7 and a remainder of 363.
Record the quotient 7 as the next digit in the result. 
Result so far: 58598.2807
If we take 4837 away from 5200, we end up with 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Moving on to step 13:
When dividing 3630 by 691, we get 5 with a remainder of 175.
The number 5 becomes the next digit in our result. 
Result so far: 58598.28075
Subtracting 3455 from 3630 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 14:
691 can be fit into 1750 2 times, resulting in a remainder of 368.
Put 2 as the next digit of the answer. 
Result so far: 58598.280752
If we take 1382 away from 1750, we end up with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Going ahead to step 15:
691 goes into 3680 5 times with a remainder of 225.
Put 5 as the next digit of the answer. 
Result so far: 58598.2807525
Subtract 3455 from 3680 to get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Moving on to step 16:
2250 divided by 691 is 3 with a remainder of 177.
The next digit of our result is 3. 
Result so far: 58598.28075253
If we subtract 2073 from 2250, we get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

After the division, we end up with 58598.28075253 and a remainder of 1.77e-07.
