75515461 ÷ 868 
Let's see how many times 868 fits into 75515461.

On to step 1:
When dividing 7 by 868, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 868

Moving on to step 2:
The number 868 fits into 75 0 times, leaving a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Bring next digit (5) of the dividend behind the 75 and repeat the process: 755 / 868

Advancing to step 3:
If we divide 755 by 868, we get 0 and a remainder of 755.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 755 after subtracting 0 from 755.
Take the next digit (1) from the dividend and append it to 755, then repeat: 7551 / 868

On to step 4:
The number 868 fits into 7551 8 times, leaving a remainder of 607.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 6944 from 7551, we get 607.
Include the next digit (5) from the dividend after 607, then repeat: 6075 / 868

Advancing to step 5:
868 goes into 6075 6 times with a remainder of 867.
Put 6 as the next digit of the answer. 
Result so far: 86.0
If we take 5208 away from 6075, we end up with 867.
Append the next digit (4) from the dividend to 867 and continue with: 8674 / 868

On to step 6:
8674 divided by 868 is 9 with a remainder of 862.
Record the quotient 9 as the next digit in the result. 
Result so far: 869.0
If we take 7812 away from 8674, we end up with 862.
Fetch the next digit (6) from the dividend, attach it to 862 and continue: 8626 / 868

Moving on to step 7:
868 goes into 8626 9 times with a remainder of 814.
Put 9 as the next digit of the answer. 
Result so far: 8699.0
The remainder is 814 after subtracting 7812 from 8626.
Bring next digit (1) of the dividend behind the 814 and repeat the process: 8141 / 868

Moving on to step 8:
When dividing 8141 by 868, we get 9 with a remainder of 329.
Put 9 as the next digit of the answer. 
Result so far: 86999.0
If we subtract 7812 from 8141, we get 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Advancing to step 9:
If we divide 3290 by 868, we get 3 and a remainder of 686.
Record the quotient 3 as the next digit in the result. 
Result so far: 86999.3
Deduct 2604 from 3290 and we're left with 686.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

Let's proceed to step 10:
868 goes into 6860 7 times with a remainder of 784.
Record the quotient 7 as the next digit in the result. 
Result so far: 86999.37
If we subtract 6076 from 6860, we get 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

Let's proceed to step 11:
The number 868 fits into 7840 9 times, leaving a remainder of 28.
Put 9 as the next digit of the answer. 
Result so far: 86999.379
The remainder is 28 after subtracting 7812 from 7840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 12:
The number 868 fits into 280 0 times, leaving a remainder of 280.
Use 0 as the next digit of our solution. 
Result so far: 86999.379
Subtracting 0 from 280 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 13:
2800 divided by 868 is 3 with a remainder of 196.
Write down 3 as next digit of the result. 
Result so far: 86999.37903
Subtract 2604 from 2800 to get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

On to step 14:
The number 868 fits into 1960 2 times, leaving a remainder of 224.
Use 2 as the next digit of our solution. 
Result so far: 86999.379032
The remainder is 224 after subtracting 1736 from 1960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Step 15:
868 goes into 2240 2 times with a remainder of 504.
Put 2 as the next digit of the answer. 
Result so far: 86999.3790322
The remainder is 504 after subtracting 1736 from 2240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Our division results in 86999.3790322 with a remaining 5.04e-06.
