Let's divide 31617769 by 86
We're looking to find how many times 86 goes into 31617769.

Going ahead to step 1:
3 divided by 86 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 86

Moving on to step 2:
86 can be fit into 31 0 times, resulting in a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Grab the next digit (6) from the dividend, add it to 31, then carry on: 316 / 86

Going ahead to step 3:
If we divide 316 by 86, we get 3 and a remainder of 58.
The next digit of our result is 3. 
Result so far: 3.0
If we take 258 away from 316, we end up with 58.
Grab the next digit (1) from the dividend, add it to 58, then carry on: 581 / 86

On to step 4:
The number 86 fits into 581 6 times, leaving a remainder of 65.
Write down 6 as next digit of the result. 
Result so far: 36.0
The remainder is 65 after subtracting 516 from 581.
Include the next digit (7) from the dividend after 65, then repeat: 657 / 86

Moving on to step 5:
86 goes into 657 7 times with a remainder of 55.
Put 7 as the next digit of the answer. 
Result so far: 367.0
If we take 602 away from 657, we end up with 55.
Bring next digit (7) of the dividend behind the 55 and repeat the process: 557 / 86

Advancing to step 6:
86 can be fit into 557 6 times, resulting in a remainder of 41.
The number 6 becomes the next digit in our result. 
Result so far: 3676.0
The remainder is 41 after subtracting 516 from 557.
Include the next digit (6) from the dividend after 41, then repeat: 416 / 86

Going ahead to step 7:
The number 86 fits into 416 4 times, leaving a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 36764.0
Subtract 344 from 416 to get 72.
Grab the next digit (9) from the dividend, add it to 72, then carry on: 729 / 86

On to step 8:
86 can be fit into 729 8 times, resulting in a remainder of 41.
Record the quotient 8 as the next digit in the result. 
Result so far: 367648.0
If we take 688 away from 729, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 9:
If we divide 410 by 86, we get 4 and a remainder of 66.
Write down 4 as next digit of the result. 
Result so far: 367648.4
If we subtract 344 from 410, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 10:
If we divide 660 by 86, we get 7 and a remainder of 58.
The next digit of our result is 7. 
Result so far: 367648.47
The remainder is 58 after subtracting 602 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 11:
If we divide 580 by 86, we get 6 and a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 367648.476
Subtract 516 from 580 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 12:
640 divided by 86 is 7 with a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 367648.4767
Deduct 602 from 640 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 13:
When dividing 380 by 86, we get 4 with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 367648.47674
Deduct 344 from 380 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 14:
If we divide 360 by 86, we get 4 and a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 367648.476744
Subtract 344 from 360 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 367648.476744, and the remainder is 1.6e-06.
