We look at the division of 91778 by 31 
Let's see how many times 31 fits into 91778.

Moving on to step 1:
If we divide 9 by 31, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 31

On to step 2:
31 goes into 91 2 times with a remainder of 29.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 62 from 91, we get 29.
Include the next digit (7) from the dividend after 29, then repeat: 297 / 31

Advancing to step 3:
When dividing 297 by 31, we get 9 with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 29.0
Deduct 279 from 297 and we're left with 18.
Take the next digit (7) from the dividend and append it to 18, then repeat: 187 / 31

Going ahead to step 4:
If we divide 187 by 31, we get 6 and a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 296.0
The remainder is 1 after subtracting 186 from 187.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 31

Advancing to step 5:
When dividing 18 by 31, we get 0 with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 2960.0
Subtracting 0 from 18 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 6:
31 goes into 180 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 2960.5
The remainder is 25 after subtracting 155 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 7:
31 can be fit into 250 8 times, resulting in a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 2960.58
Subtracting 248 from 250 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
The number 31 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 2960.58
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
The number 31 fits into 200 6 times, leaving a remainder of 14.
The next digit of our result is 6. 
Result so far: 2960.5806
Subtracting 186 from 200 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 10:
If we divide 140 by 31, we get 4 and a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 2960.58064
If we subtract 124 from 140, we 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.

Let's proceed to step 11:
31 goes into 160 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 2960.580645
The remainder is 5 after subtracting 155 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 12:
31 can be fit into 50 1 times, resulting in a remainder of 19.
The next digit of our result is 1. 
Result so far: 2960.5806451
Deduct 31 from 50 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 13:
When dividing 190 by 31, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 2960.58064516
If we take 186 away from 190, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 2960.58064516 with a balance of 4e-09.
