We divide 9121592 by 580
We want to figure out the number of times 9121592 can be divided by 580.

On to step 1:
580 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 580

Going ahead to step 2:
When dividing 91 by 580, we get 0 with a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Take the next digit (2) from the dividend and append it to 91, then repeat: 912 / 580

Let's proceed to step 3:
580 goes into 912 1 times with a remainder of 332.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 580 from 912 and we're left with 332.
Include the next digit (1) from the dividend after 332, then repeat: 3321 / 580

On to step 4:
The number 580 fits into 3321 5 times, leaving a remainder of 421.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtracting 2900 from 3321 leaves us with 421.
Append the next digit (5) from the dividend to 421 and continue with: 4215 / 580

Step 5:
4215 divided by 580 is 7 with a remainder of 155.
The number 7 becomes the next digit in our result. 
Result so far: 157.0
If we take 4060 away from 4215, we end up with 155.
Append the next digit (9) from the dividend to 155 and continue with: 1559 / 580

Let's proceed to step 6:
If we divide 1559 by 580, we get 2 and a remainder of 399.
Record the quotient 2 as the next digit in the result. 
Result so far: 1572.0
The remainder is 399 after subtracting 1160 from 1559.
Bring next digit (2) of the dividend behind the 399 and repeat the process: 3992 / 580

On to step 7:
580 can be fit into 3992 6 times, resulting in a remainder of 512.
Put 6 as the next digit of the answer. 
Result so far: 15726.0
Subtracting 3480 from 3992 leaves us with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Let's proceed to step 8:
The number 580 fits into 5120 8 times, leaving a remainder of 480.
Use 8 as the next digit of our solution. 
Result so far: 15726.8
Deduct 4640 from 5120 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 9:
580 can be fit into 4800 8 times, resulting in a remainder of 160.
Record the quotient 8 as the next digit in the result. 
Result so far: 15726.88
Subtract 4640 from 4800 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final result is 15726.88 with a remainder of 0.16.
