Let's divide 31079094 by 86
We want to divide 31079094 by 86.

Step 1:
When dividing 3 by 86, we get 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.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 86

Let's proceed to step 2:
86 goes into 31 0 times with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Take the next digit (0) from the dividend and append it to 31, then repeat: 310 / 86

Step 3:
When dividing 310 by 86, we get 3 with a remainder of 52.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 52 after subtracting 258 from 310.
Take the next digit (7) from the dividend and append it to 52, then repeat: 527 / 86

Step 4:
If we divide 527 by 86, we get 6 and a remainder of 11.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
Subtract 516 from 527 to get 11.
Include the next digit (9) from the dividend after 11, then repeat: 119 / 86

Going ahead to step 5:
86 can be fit into 119 1 times, resulting in a remainder of 33.
Use 1 as the next digit of our solution. 
Result so far: 361.0
Subtract 86 from 119 to get 33.
Include the next digit (0) from the dividend after 33, then repeat: 330 / 86

Moving on to step 6:
The number 86 fits into 330 3 times, leaving a remainder of 72.
Use 3 as the next digit of our solution. 
Result so far: 3613.0
The remainder is 72 after subtracting 258 from 330.
Include the next digit (9) from the dividend after 72, then repeat: 729 / 86

On to step 7:
86 can be fit into 729 8 times, resulting in a remainder of 41.
The number 8 becomes the next digit in our result. 
Result so far: 36138.0
Subtract 688 from 729 to get 41.
Grab the next digit (4) from the dividend, add it to 41, then carry on: 414 / 86

Moving on to step 8:
The number 86 fits into 414 4 times, leaving a remainder of 70.
Use 4 as the next digit of our solution. 
Result so far: 361384.0
The remainder is 70 after subtracting 344 from 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 9:
When dividing 700 by 86, we get 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 361384.8
The remainder is 12 after subtracting 688 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 10:
86 goes into 120 1 times with a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 361384.81
Subtracting 86 from 120 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 11:
340 divided by 86 is 3 with a remainder of 82.
Record the quotient 3 as the next digit in the result. 
Result so far: 361384.813
Deduct 258 from 340 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 12:
When dividing 820 by 86, we get 9 with a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 361384.8139
If we take 774 away from 820, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 13:
86 can be fit into 460 5 times, resulting in a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 361384.81395
Subtracting 430 from 460 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 14:
300 divided by 86 is 3 with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 361384.813953
If we subtract 258 from 300, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 15:
420 divided by 86 is 4 with a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 361384.8139534
If we subtract 344 from 420, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 16:
The number 86 fits into 760 8 times, leaving a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 361384.81395348
Deduct 688 from 760 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

In conclusion, the division gives 361384.81395348 with a balance of 7.2e-08.
