966931 ÷ 90 
We're looking to find how many times 90 goes into 966931.

Moving on to step 1:
90 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 90

Let's proceed to step 2:
If we divide 96 by 90, we get 1 and a remainder of 6.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 90 from 96, we get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 90

On to step 3:
90 goes into 66 0 times with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 66 and we're left with 66.
Fetch the next digit (9) from the dividend, attach it to 66 and continue: 669 / 90

Advancing to step 4:
If we divide 669 by 90, we get 7 and a remainder of 39.
The next digit of our result is 7. 
Result so far: 107.0
Subtract 630 from 669 to get 39.
Fetch the next digit (3) from the dividend, attach it to 39 and continue: 393 / 90

On to step 5:
393 divided by 90 is 4 with a remainder of 33.
Record the quotient 4 as the next digit in the result. 
Result so far: 1074.0
The remainder is 33 after subtracting 360 from 393.
Append the next digit (1) from the dividend to 33 and continue with: 331 / 90

Advancing to step 6:
If we divide 331 by 90, we get 3 and a remainder of 61.
Use 3 as the next digit of our solution. 
Result so far: 10743.0
Subtract 270 from 331 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 7:
90 goes into 610 6 times with a remainder of 70.
Put 6 as the next digit of the answer. 
Result so far: 10743.6
If we subtract 540 from 610, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 8:
90 goes into 700 7 times with a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 10743.67
Subtract 630 from 700 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 9:
The number 90 fits into 700 7 times, leaving a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 10743.677
Deduct 630 from 700 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 10743.677, with a leftover of 0.007.
