Let's divide 157415 by 90
We want to figure out the number of times 157415 can be divided by 90.

Let's proceed to step 1:
When dividing 1 by 90, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 90

On to step 2:
When dividing 15 by 90, we get 0 with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 90

Advancing to step 3:
157 divided by 90 is 1 with a remainder of 67.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 90 away from 157, we end up with 67.
Take the next digit (4) from the dividend and append it to 67, then repeat: 674 / 90

Step 4:
When dividing 674 by 90, we get 7 with a remainder of 44.
Put 7 as the next digit of the answer. 
Result so far: 17.0
The remainder is 44 after subtracting 630 from 674.
Fetch the next digit (1) from the dividend, attach it to 44 and continue: 441 / 90

On to step 5:
When dividing 441 by 90, we get 4 with a remainder of 81.
The number 4 becomes the next digit in our result. 
Result so far: 174.0
If we subtract 360 from 441, we get 81.
Fetch the next digit (5) from the dividend, attach it to 81 and continue: 815 / 90

Step 6:
90 can be fit into 815 9 times, resulting in a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 1749.0
Subtract 810 from 815 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
50 divided by 90 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 1749.0
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
90 can be fit into 500 5 times, resulting in a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 1749.05
If we take 450 away from 500, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
90 goes into 500 5 times with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 1749.055
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 1749.055 with a remainder of 0.005.
