90386157 ÷ 830 
We want to divide 90386157 by 830.

On to step 1:
830 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 830

Step 2:
830 goes into 90 0 times with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Include the next digit (3) from the dividend after 90, then repeat: 903 / 830

On to step 3:
830 goes into 903 1 times with a remainder of 73.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 73 after subtracting 830 from 903.
Fetch the next digit (8) from the dividend, attach it to 73 and continue: 738 / 830

Advancing to step 4:
830 goes into 738 0 times with a remainder of 738.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 738 and we're left with 738.
Fetch the next digit (6) from the dividend, attach it to 738 and continue: 7386 / 830

Advancing to step 5:
830 can be fit into 7386 8 times, resulting in a remainder of 746.
Use 8 as the next digit of our solution. 
Result so far: 108.0
The remainder is 746 after subtracting 6640 from 7386.
Bring next digit (1) of the dividend behind the 746 and repeat the process: 7461 / 830

Step 6:
830 goes into 7461 8 times with a remainder of 821.
The next digit of our result is 8. 
Result so far: 1088.0
Subtracting 6640 from 7461 leaves us with 821.
Include the next digit (5) from the dividend after 821, then repeat: 8215 / 830

Moving on to step 7:
8215 divided by 830 is 9 with a remainder of 745.
Use 9 as the next digit of our solution. 
Result so far: 10889.0
Subtract 7470 from 8215 to get 745.
Include the next digit (7) from the dividend after 745, then repeat: 7457 / 830

Moving on to step 8:
The number 830 fits into 7457 8 times, leaving a remainder of 817.
Write down 8 as next digit of the result. 
Result so far: 108898.0
If we subtract 6640 from 7457, we get 817.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8170, and continue the process.

Advancing to step 9:
8170 divided by 830 is 9 with a remainder of 700.
Use 9 as the next digit of our solution. 
Result so far: 108898.9
Deduct 7470 from 8170 and we're left with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

On to step 10:
When dividing 7000 by 830, we get 8 with a remainder of 360.
The number 8 becomes the next digit in our result. 
Result so far: 108898.98
If we subtract 6640 from 7000, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 11:
When dividing 3600 by 830, we get 4 with a remainder of 280.
The next digit of our result is 4. 
Result so far: 108898.984
Subtract 3320 from 3600 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 12:
If we divide 2800 by 830, we get 3 and a remainder of 310.
Put 3 as the next digit of the answer. 
Result so far: 108898.9843
Subtracting 2490 from 2800 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Let's proceed to step 13:
The number 830 fits into 3100 3 times, leaving a remainder of 610.
Put 3 as the next digit of the answer. 
Result so far: 108898.98433
The remainder is 610 after subtracting 2490 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Our division results in 108898.98433 with a remaining 0.00061.
