We look at the division of 160144 by 90 
We want to figure out the number of times 160144 can be divided by 90.

On to step 1:
1 divided by 90 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 90

On to step 2:
If we divide 16 by 90, we get 0 and a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Grab the next digit (0) from the dividend, add it to 16, then carry on: 160 / 90

Moving on to step 3:
160 divided by 90 is 1 with a remainder of 70.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 90 from 160 leaves us with 70.
Include the next digit (1) from the dividend after 70, then repeat: 701 / 90

Step 4:
701 divided by 90 is 7 with a remainder of 71.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtracting 630 from 701 leaves us with 71.
Grab the next digit (4) from the dividend, add it to 71, then carry on: 714 / 90

Going ahead to step 5:
90 can be fit into 714 7 times, resulting in a remainder of 84.
Put 7 as the next digit of the answer. 
Result so far: 177.0
If we take 630 away from 714, we end up with 84.
Include the next digit (4) from the dividend after 84, then repeat: 844 / 90

Advancing to step 6:
When dividing 844 by 90, we get 9 with a remainder of 34.
The next digit of our result is 9. 
Result so far: 1779.0
Subtracting 810 from 844 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 7:
When dividing 340 by 90, we get 3 with a remainder of 70.
Record the quotient 3 as the next digit in the result. 
Result so far: 1779.3
Subtract 270 from 340 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 8:
The number 90 fits into 700 7 times, leaving a remainder of 70.
The next digit of our result is 7. 
Result so far: 1779.37
The remainder is 70 after subtracting 630 from 700.
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 9:
The number 90 fits into 700 7 times, leaving a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 1779.377
If we take 630 away from 700, we end up 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 1779.377, with a leftover of 0.007.
