We're dividing 75478669 by 864 
We want to divide 75478669 by 864.

Let's proceed to step 1:
864 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 864

Moving on to step 2:
If we divide 75 by 864, we get 0 and a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Fetch the next digit (4) from the dividend, attach it to 75 and continue: 754 / 864

Step 3:
When dividing 754 by 864, we get 0 with a remainder of 754.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 754 after subtracting 0 from 754.
Append the next digit (7) from the dividend to 754 and continue with: 7547 / 864

Moving on to step 4:
7547 divided by 864 is 8 with a remainder of 635.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 6912 from 7547 to get 635.
Fetch the next digit (8) from the dividend, attach it to 635 and continue: 6358 / 864

Let's proceed to step 5:
When dividing 6358 by 864, we get 7 with a remainder of 310.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
Deduct 6048 from 6358 and we're left with 310.
Grab the next digit (6) from the dividend, add it to 310, then carry on: 3106 / 864

Going ahead to step 6:
864 goes into 3106 3 times with a remainder of 514.
Use 3 as the next digit of our solution. 
Result so far: 873.0
If we take 2592 away from 3106, we end up with 514.
Grab the next digit (6) from the dividend, add it to 514, then carry on: 5146 / 864

Step 7:
864 goes into 5146 5 times with a remainder of 826.
Put 5 as the next digit of the answer. 
Result so far: 8735.0
Subtracting 4320 from 5146 leaves us with 826.
Fetch the next digit (9) from the dividend, attach it to 826 and continue: 8269 / 864

On to step 8:
864 can be fit into 8269 9 times, resulting in a remainder of 493.
Write down 9 as next digit of the result. 
Result so far: 87359.0
Subtract 7776 from 8269 to get 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

Step 9:
If we divide 4930 by 864, we get 5 and a remainder of 610.
The next digit of our result is 5. 
Result so far: 87359.5
Deduct 4320 from 4930 and we're left with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Advancing to step 10:
If we divide 6100 by 864, we get 7 and a remainder of 52.
The next digit of our result is 7. 
Result so far: 87359.57
If we take 6048 away from 6100, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 11:
864 can be fit into 520 0 times, resulting in a remainder of 520.
Use 0 as the next digit of our solution. 
Result so far: 87359.57
Subtract 0 from 520 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 12:
5200 divided by 864 is 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 87359.5706
The remainder is 16 after subtracting 5184 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 13:
The number 864 fits into 160 0 times, leaving a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 87359.5706
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 14:
If we divide 1600 by 864, we get 1 and a remainder of 736.
Put 1 as the next digit of the answer. 
Result so far: 87359.570601
The remainder is 736 after subtracting 864 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Let's proceed to step 15:
864 goes into 7360 8 times with a remainder of 448.
Put 8 as the next digit of the answer. 
Result so far: 87359.5706018
Subtract 6912 from 7360 to get 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 864 fits into 4480 5 times, leaving a remainder of 160.
The number 5 becomes the next digit in our result. 
Result so far: 87359.57060185
Deduct 4320 from 4480 and we're left with 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 quotient of the division is 87359.57060185, and the remainder is 1.6e-07.
