Let's divide 169900 by 9
We want to figure out the number of times 169900 can be divided by 9.

Advancing to step 1:
When dividing 1 by 9, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 9

On to step 2:
9 can be fit into 16 1 times, resulting in a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 9 from 16 to get 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 9

Step 3:
The number 9 fits into 79 8 times, leaving a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Deduct 72 from 79 and we're left with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 9

Going ahead to step 4:
If we divide 79 by 9, we get 8 and a remainder of 7.
The next digit of our result is 8. 
Result so far: 188.0
If we subtract 72 from 79, we get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 9

Advancing to step 5:
If we divide 70 by 9, we get 7 and a remainder of 7.
The next digit of our result is 7. 
Result so far: 1887.0
Subtracting 63 from 70 leaves us with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 9

Advancing to step 6:
If we divide 70 by 9, we get 7 and a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 18877.0
Subtracting 63 from 70 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
If we divide 70 by 9, we get 7 and a remainder of 7.
The next digit of our result is 7. 
Result so far: 18877.7
If we take 63 away from 70, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 8:
When dividing 70 by 9, we get 7 with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 18877.77
If we subtract 63 from 70, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The quotient of the division is 18877.77, and the remainder is 0.007.
