51729828 ÷ 691 
We're looking to find how many times 691 goes into 51729828.

On to step 1:
When dividing 5 by 691, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 691

Let's proceed to step 2:
If we divide 51 by 691, we get 0 and a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Take the next digit (7) from the dividend and append it to 51, then repeat: 517 / 691

On to step 3:
If we divide 517 by 691, we get 0 and a remainder of 517.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 517, we end up with 517.
Grab the next digit (2) from the dividend, add it to 517, then carry on: 5172 / 691

Step 4:
5172 divided by 691 is 7 with a remainder of 335.
The next digit of our result is 7. 
Result so far: 7.0
If we take 4837 away from 5172, we end up with 335.
Take the next digit (9) from the dividend and append it to 335, then repeat: 3359 / 691

Let's proceed to step 5:
If we divide 3359 by 691, we get 4 and a remainder of 595.
Put 4 as the next digit of the answer. 
Result so far: 74.0
Deduct 2764 from 3359 and we're left with 595.
Include the next digit (8) from the dividend after 595, then repeat: 5958 / 691

Moving on to step 6:
If we divide 5958 by 691, we get 8 and a remainder of 430.
The number 8 becomes the next digit in our result. 
Result so far: 748.0
Subtracting 5528 from 5958 leaves us with 430.
Include the next digit (2) from the dividend after 430, then repeat: 4302 / 691

On to step 7:
When dividing 4302 by 691, we get 6 with a remainder of 156.
Use 6 as the next digit of our solution. 
Result so far: 7486.0
Deduct 4146 from 4302 and we're left with 156.
Append the next digit (8) from the dividend to 156 and continue with: 1568 / 691

On to step 8:
If we divide 1568 by 691, we get 2 and a remainder of 186.
Use 2 as the next digit of our solution. 
Result so far: 74862.0
Subtracting 1382 from 1568 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Let's proceed to step 9:
1860 divided by 691 is 2 with a remainder of 478.
Record the quotient 2 as the next digit in the result. 
Result so far: 74862.2
Deduct 1382 from 1860 and we're left with 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Advancing to step 10:
691 can be fit into 4780 6 times, resulting in a remainder of 634.
The number 6 becomes the next digit in our result. 
Result so far: 74862.26
Subtracting 4146 from 4780 leaves us with 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

Moving on to step 11:
If we divide 6340 by 691, we get 9 and a remainder of 121.
The number 9 becomes the next digit in our result. 
Result so far: 74862.269
Subtracting 6219 from 6340 leaves us with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Step 12:
691 can be fit into 1210 1 times, resulting in a remainder of 519.
Use 1 as the next digit of our solution. 
Result so far: 74862.2691
Subtracting 691 from 1210 leaves us with 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

Let's proceed to step 13:
If we divide 5190 by 691, we get 7 and a remainder of 353.
Use 7 as the next digit of our solution. 
Result so far: 74862.26917
The remainder is 353 after subtracting 4837 from 5190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Advancing to step 14:
If we divide 3530 by 691, we get 5 and a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 74862.269175
If we subtract 3455 from 3530, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 15:
691 goes into 750 1 times with a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 74862.2691751
Subtracting 691 from 750 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 16:
691 goes into 590 0 times with a remainder of 590.
The next digit of our result is 0. 
Result so far: 74862.2691751
If we subtract 0 from 590, we get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

The quotient of the division is 74862.2691751, and the remainder is 5.9e-07.
