86508221 ÷ 755 
We want to divide 86508221 by 755.

Advancing to step 1:
8 divided by 755 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 755

Advancing to step 2:
755 can be fit into 86 0 times, resulting in a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Fetch the next digit (5) from the dividend, attach it to 86 and continue: 865 / 755

Going ahead to step 3:
755 can be fit into 865 1 times, resulting in a remainder of 110.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 755 away from 865, we end up with 110.
Include the next digit (0) from the dividend after 110, then repeat: 1100 / 755

Step 4:
The number 755 fits into 1100 1 times, leaving a remainder of 345.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 345 after subtracting 755 from 1100.
Grab the next digit (8) from the dividend, add it to 345, then carry on: 3458 / 755

On to step 5:
The number 755 fits into 3458 4 times, leaving a remainder of 438.
Write down 4 as next digit of the result. 
Result so far: 114.0
The remainder is 438 after subtracting 3020 from 3458.
Include the next digit (2) from the dividend after 438, then repeat: 4382 / 755

Step 6:
755 goes into 4382 5 times with a remainder of 607.
Record the quotient 5 as the next digit in the result. 
Result so far: 1145.0
Deduct 3775 from 4382 and we're left with 607.
Bring next digit (2) of the dividend behind the 607 and repeat the process: 6072 / 755

On to step 7:
The number 755 fits into 6072 8 times, leaving a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 11458.0
If we take 6040 away from 6072, we end up with 32.
Include the next digit (1) from the dividend after 32, then repeat: 321 / 755

Let's proceed to step 8:
The number 755 fits into 321 0 times, leaving a remainder of 321.
Put 0 as the next digit of the answer. 
Result so far: 114580.0
If we take 0 away from 321, we end up with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Advancing to step 9:
When dividing 3210 by 755, we get 4 with a remainder of 190.
Write down 4 as next digit of the result. 
Result so far: 114580.4
If we subtract 3020 from 3210, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 10:
755 goes into 1900 2 times with a remainder of 390.
Use 2 as the next digit of our solution. 
Result so far: 114580.42
If we subtract 1510 from 1900, we get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Advancing to step 11:
When dividing 3900 by 755, we get 5 with a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 114580.425
Subtracting 3775 from 3900 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 12:
If we divide 1250 by 755, we get 1 and a remainder of 495.
The next digit of our result is 1. 
Result so far: 114580.4251
If we subtract 755 from 1250, we get 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Let's proceed to step 13:
The number 755 fits into 4950 6 times, leaving a remainder of 420.
Write down 6 as next digit of the result. 
Result so far: 114580.42516
Subtract 4530 from 4950 to get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Going ahead to step 14:
755 goes into 4200 5 times with a remainder of 425.
Use 5 as the next digit of our solution. 
Result so far: 114580.425165
Subtract 3775 from 4200 to get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Moving on to step 15:
4250 divided by 755 is 5 with a remainder of 475.
Write down 5 as next digit of the result. 
Result so far: 114580.4251655
Subtracting 3775 from 4250 leaves us with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

The final outcome is 114580.4251655, with a leftover of 4.75e-06.
