We divide 59921228 by 90
We want to figure out the number of times 59921228 can be divided by 90.

Going ahead to step 1:
90 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 90

On to step 2:
90 goes into 59 0 times with a remainder of 59.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 59, we get 59.
Fetch the next digit (9) from the dividend, attach it to 59 and continue: 599 / 90

Moving on to step 3:
If we divide 599 by 90, we get 6 and a remainder of 59.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 540 from 599 leaves us with 59.
Fetch the next digit (2) from the dividend, attach it to 59 and continue: 592 / 90

Step 4:
592 divided by 90 is 6 with a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 66.0
Subtract 540 from 592 to get 52.
Bring next digit (1) of the dividend behind the 52 and repeat the process: 521 / 90

Step 5:
The number 90 fits into 521 5 times, leaving a remainder of 71.
The next digit of our result is 5. 
Result so far: 665.0
If we subtract 450 from 521, we get 71.
Fetch the next digit (2) from the dividend, attach it to 71 and continue: 712 / 90

Moving on to step 6:
90 can be fit into 712 7 times, resulting in a remainder of 82.
Put 7 as the next digit of the answer. 
Result so far: 6657.0
Subtracting 630 from 712 leaves us with 82.
Include the next digit (2) from the dividend after 82, then repeat: 822 / 90

Let's proceed to step 7:
When dividing 822 by 90, we get 9 with a remainder of 12.
The next digit of our result is 9. 
Result so far: 66579.0
If we subtract 810 from 822, we get 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 90

Step 8:
128 divided by 90 is 1 with a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 665791.0
If we subtract 90 from 128, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 9:
The number 90 fits into 380 4 times, leaving a remainder of 20.
The next digit of our result is 4. 
Result so far: 665791.4
Deduct 360 from 380 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
90 can be fit into 200 2 times, resulting in a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 665791.42
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 11:
90 goes into 200 2 times with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 665791.422
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 665791.422 with a remainder of 0.002.
