53959836 ÷ 691 
We want to figure out the number of times 53959836 can be divided by 691.

Step 1:
5 divided by 691 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 691

Moving on to step 2:
The number 691 fits into 53 0 times, leaving a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Include the next digit (9) from the dividend after 53, then repeat: 539 / 691

Moving on to step 3:
If we divide 539 by 691, we get 0 and a remainder of 539.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 539 to get 539.
Fetch the next digit (5) from the dividend, attach it to 539 and continue: 5395 / 691

Moving on to step 4:
The number 691 fits into 5395 7 times, leaving a remainder of 558.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 4837 away from 5395, we end up with 558.
Fetch the next digit (9) from the dividend, attach it to 558 and continue: 5589 / 691

Let's proceed to step 5:
When dividing 5589 by 691, we get 8 with a remainder of 61.
Write down 8 as next digit of the result. 
Result so far: 78.0
If we subtract 5528 from 5589, we get 61.
Fetch the next digit (8) from the dividend, attach it to 61 and continue: 618 / 691

Advancing to step 6:
When dividing 618 by 691, we get 0 with a remainder of 618.
Record the quotient 0 as the next digit in the result. 
Result so far: 780.0
Subtract 0 from 618 to get 618.
Include the next digit (3) from the dividend after 618, then repeat: 6183 / 691

On to step 7:
If we divide 6183 by 691, we get 8 and a remainder of 655.
Put 8 as the next digit of the answer. 
Result so far: 7808.0
Subtract 5528 from 6183 to get 655.
Include the next digit (6) from the dividend after 655, then repeat: 6556 / 691

Let's proceed to step 8:
691 goes into 6556 9 times with a remainder of 337.
Use 9 as the next digit of our solution. 
Result so far: 78089.0
The remainder is 337 after subtracting 6219 from 6556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Let's proceed to step 9:
691 goes into 3370 4 times with a remainder of 606.
The next digit of our result is 4. 
Result so far: 78089.4
The remainder is 606 after subtracting 2764 from 3370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

Let's proceed to step 10:
691 can be fit into 6060 8 times, resulting in a remainder of 532.
The next digit of our result is 8. 
Result so far: 78089.48
If we subtract 5528 from 6060, we get 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Going ahead to step 11:
When dividing 5320 by 691, we get 7 with a remainder of 483.
The number 7 becomes the next digit in our result. 
Result so far: 78089.487
If we take 4837 away from 5320, we end up with 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

On to step 12:
If we divide 4830 by 691, we get 6 and a remainder of 684.
Write down 6 as next digit of the result. 
Result so far: 78089.4876
Deduct 4146 from 4830 and we're left with 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

Step 13:
691 can be fit into 6840 9 times, resulting in a remainder of 621.
Use 9 as the next digit of our solution. 
Result so far: 78089.48769
If we take 6219 away from 6840, we end up with 621.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6210, and continue the process.

Advancing to step 14:
When dividing 6210 by 691, we get 8 with a remainder of 682.
Put 8 as the next digit of the answer. 
Result so far: 78089.487698
Subtracting 5528 from 6210 leaves us with 682.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6820, and continue the process.

Moving on to step 15:
When dividing 6820 by 691, we get 9 with a remainder of 601.
Use 9 as the next digit of our solution. 
Result so far: 78089.4876989
If we take 6219 away from 6820, we end up with 601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

Going ahead to step 16:
The number 691 fits into 6010 8 times, leaving a remainder of 482.
Use 8 as the next digit of our solution. 
Result so far: 78089.48769898
Deduct 5528 from 6010 and we're left with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

The quotient of the division is 78089.48769898, and the remainder is 4.82e-07.
