We're dividing 90456270 by 869 
We want to figure out the number of times 90456270 can be divided by 869.

Step 1:
The number 869 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 869

Going ahead to step 2:
The number 869 fits into 90 0 times, leaving a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Grab the next digit (4) from the dividend, add it to 90, then carry on: 904 / 869

Moving on to step 3:
The number 869 fits into 904 1 times, leaving a remainder of 35.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 869 from 904 leaves us with 35.
Include the next digit (5) from the dividend after 35, then repeat: 355 / 869

Step 4:
The number 869 fits into 355 0 times, leaving a remainder of 355.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 355, we get 355.
Bring next digit (6) of the dividend behind the 355 and repeat the process: 3556 / 869

Moving on to step 5:
If we divide 3556 by 869, we get 4 and a remainder of 80.
Put 4 as the next digit of the answer. 
Result so far: 104.0
The remainder is 80 after subtracting 3476 from 3556.
Include the next digit (2) from the dividend after 80, then repeat: 802 / 869

On to step 6:
When dividing 802 by 869, we get 0 with a remainder of 802.
The number 0 becomes the next digit in our result. 
Result so far: 1040.0
If we take 0 away from 802, we end up with 802.
Include the next digit (7) from the dividend after 802, then repeat: 8027 / 869

Step 7:
869 goes into 8027 9 times with a remainder of 206.
Record the quotient 9 as the next digit in the result. 
Result so far: 10409.0
If we take 7821 away from 8027, we end up with 206.
Append the next digit (0) from the dividend to 206 and continue with: 2060 / 869

Moving on to step 8:
2060 divided by 869 is 2 with a remainder of 322.
Record the quotient 2 as the next digit in the result. 
Result so far: 104092.0
Subtract 1738 from 2060 to get 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Step 9:
The number 869 fits into 3220 3 times, leaving a remainder of 613.
Write down 3 as next digit of the result. 
Result so far: 104092.3
The remainder is 613 after subtracting 2607 from 3220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6130, and continue the process.

Step 10:
869 goes into 6130 7 times with a remainder of 47.
Record the quotient 7 as the next digit in the result. 
Result so far: 104092.37
If we take 6083 away from 6130, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 11:
869 can be fit into 470 0 times, resulting in a remainder of 470.
Use 0 as the next digit of our solution. 
Result so far: 104092.37
Deduct 0 from 470 and we're left with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Advancing to step 12:
869 goes into 4700 5 times with a remainder of 355.
The next digit of our result is 5. 
Result so far: 104092.3705
If we subtract 4345 from 4700, we get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

On to step 13:
If we divide 3550 by 869, we get 4 and a remainder of 74.
The number 4 becomes the next digit in our result. 
Result so far: 104092.37054
If we subtract 3476 from 3550, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 14:
When dividing 740 by 869, we get 0 with a remainder of 740.
Write down 0 as next digit of the result. 
Result so far: 104092.37054
If we subtract 0 from 740, we get 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Moving on to step 15:
If we divide 7400 by 869, we get 8 and a remainder of 448.
Use 8 as the next digit of our solution. 
Result so far: 104092.3705408
If we take 6952 away from 7400, we end up with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

On to step 16:
The number 869 fits into 4480 5 times, leaving a remainder of 135.
Write down 5 as next digit of the result. 
Result so far: 104092.37054085
Deduct 4345 from 4480 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

The quotient of the division is 104092.37054085, and the remainder is 1.35e-07.
