51836739 ÷ 691 
We want to figure out the number of times 51836739 can be divided by 691.

Step 1:
When dividing 5 by 691, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 691

Moving on to step 2:
691 can be fit into 51 0 times, resulting in a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Append the next digit (8) from the dividend to 51 and continue with: 518 / 691

Advancing to step 3:
If we divide 518 by 691, we get 0 and a remainder of 518.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 518 and we're left with 518.
Take the next digit (3) from the dividend and append it to 518, then repeat: 5183 / 691

Moving on to step 4:
If we divide 5183 by 691, we get 7 and a remainder of 346.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 4837 from 5183 and we're left with 346.
Grab the next digit (6) from the dividend, add it to 346, then carry on: 3466 / 691

Going ahead to step 5:
The number 691 fits into 3466 5 times, leaving a remainder of 11.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
If we subtract 3455 from 3466, we get 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 691

Step 6:
117 divided by 691 is 0 with a remainder of 117.
Write down 0 as next digit of the result. 
Result so far: 750.0
If we take 0 away from 117, we end up with 117.
Include the next digit (3) from the dividend after 117, then repeat: 1173 / 691

Moving on to step 7:
When dividing 1173 by 691, we get 1 with a remainder of 482.
Put 1 as the next digit of the answer. 
Result so far: 7501.0
Subtracting 691 from 1173 leaves us with 482.
Take the next digit (9) from the dividend and append it to 482, then repeat: 4829 / 691

On to step 8:
If we divide 4829 by 691, we get 6 and a remainder of 683.
The next digit of our result is 6. 
Result so far: 75016.0
If we subtract 4146 from 4829, we get 683.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6830, and continue the process.

Advancing to step 9:
When dividing 6830 by 691, we get 9 with a remainder of 611.
Use 9 as the next digit of our solution. 
Result so far: 75016.9
If we subtract 6219 from 6830, we get 611.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6110, and continue the process.

Let's proceed to step 10:
The number 691 fits into 6110 8 times, leaving a remainder of 582.
Record the quotient 8 as the next digit in the result. 
Result so far: 75016.98
Subtracting 5528 from 6110 leaves us with 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

Step 11:
5820 divided by 691 is 8 with a remainder of 292.
The number 8 becomes the next digit in our result. 
Result so far: 75016.988
Deduct 5528 from 5820 and we're left with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

The quotient of the division is 75016.988, and the remainder is 0.0292.
