915558 ÷ 9 
We want to figure out the number of times 915558 can be divided by 9.

Advancing to step 1:
The number 9 fits into 9 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 0 after subtracting 9 from 9.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 9

On to step 2:
The number 9 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 1, we get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 9

Going ahead to step 3:
If we divide 15 by 9, we get 1 and a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 101.0
If we subtract 9 from 15, we get 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 9

On to step 4:
If we divide 65 by 9, we get 7 and a remainder of 2.
The next digit of our result is 7. 
Result so far: 1017.0
Deduct 63 from 65 and we're left with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 9

Advancing to step 5:
25 divided by 9 is 2 with a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 10172.0
If we subtract 18 from 25, we get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 9

On to step 6:
When dividing 78 by 9, we get 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 101728.0
Deduct 72 from 78 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
9 goes into 60 6 times with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 101728.6
If we subtract 54 from 60, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
When dividing 60 by 9, we get 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 101728.66
Subtract 54 from 60 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 101728.66, with a leftover of 0.006.
