We look at the division of 84788978 by 931 
We want to figure out the number of times 84788978 can be divided by 931.

Let's proceed to step 1:
If we divide 8 by 931, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 931

Going ahead to step 2:
When dividing 84 by 931, we get 0 with a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 84, we end up with 84.
Bring next digit (7) of the dividend behind the 84 and repeat the process: 847 / 931

On to step 3:
If we divide 847 by 931, we get 0 and a remainder of 847.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 847, we end up with 847.
Fetch the next digit (8) from the dividend, attach it to 847 and continue: 8478 / 931

Moving on to step 4:
931 can be fit into 8478 9 times, resulting in a remainder of 99.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 8379 away from 8478, we end up with 99.
Append the next digit (8) from the dividend to 99 and continue with: 998 / 931

Moving on to step 5:
When dividing 998 by 931, we get 1 with a remainder of 67.
Put 1 as the next digit of the answer. 
Result so far: 91.0
If we take 931 away from 998, we end up with 67.
Grab the next digit (9) from the dividend, add it to 67, then carry on: 679 / 931

Step 6:
931 can be fit into 679 0 times, resulting in a remainder of 679.
Use 0 as the next digit of our solution. 
Result so far: 910.0
Subtract 0 from 679 to get 679.
Append the next digit (7) from the dividend to 679 and continue with: 6797 / 931

Let's proceed to step 7:
6797 divided by 931 is 7 with a remainder of 280.
Put 7 as the next digit of the answer. 
Result so far: 9107.0
If we take 6517 away from 6797, we end up with 280.
Append the next digit (8) from the dividend to 280 and continue with: 2808 / 931

On to step 8:
The number 931 fits into 2808 3 times, leaving a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 91073.0
Deduct 2793 from 2808 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 9:
931 goes into 150 0 times with a remainder of 150.
The next digit of our result is 0. 
Result so far: 91073.0
Subtract 0 from 150 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 10:
When dividing 1500 by 931, we get 1 with a remainder of 569.
Put 1 as the next digit of the answer. 
Result so far: 91073.01
If we subtract 931 from 1500, we get 569.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5690, and continue the process.

On to step 11:
931 can be fit into 5690 6 times, resulting in a remainder of 104.
The number 6 becomes the next digit in our result. 
Result so far: 91073.016
If we take 5586 away from 5690, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 12:
931 goes into 1040 1 times with a remainder of 109.
Put 1 as the next digit of the answer. 
Result so far: 91073.0161
Deduct 931 from 1040 and we're left with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Let's proceed to step 13:
If we divide 1090 by 931, we get 1 and a remainder of 159.
The next digit of our result is 1. 
Result so far: 91073.01611
Subtract 931 from 1090 to get 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

The final outcome is 91073.01611, with a leftover of 0.000159.
