We're dividing 86174992 by 802 
Our goal is to divide 86174992 by 802.

Let's proceed to step 1:
The number 802 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 802

Step 2:
802 can be fit into 86 0 times, resulting in a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Grab the next digit (1) from the dividend, add it to 86, then carry on: 861 / 802

Advancing to step 3:
The number 802 fits into 861 1 times, leaving a remainder of 59.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 802 from 861, we get 59.
Take the next digit (7) from the dividend and append it to 59, then repeat: 597 / 802

Moving on to step 4:
When dividing 597 by 802, we get 0 with a remainder of 597.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 597 after subtracting 0 from 597.
Take the next digit (4) from the dividend and append it to 597, then repeat: 5974 / 802

On to step 5:
The number 802 fits into 5974 7 times, leaving a remainder of 360.
Write down 7 as next digit of the result. 
Result so far: 107.0
Deduct 5614 from 5974 and we're left with 360.
Take the next digit (9) from the dividend and append it to 360, then repeat: 3609 / 802

Going ahead to step 6:
The number 802 fits into 3609 4 times, leaving a remainder of 401.
Put 4 as the next digit of the answer. 
Result so far: 1074.0
Subtract 3208 from 3609 to get 401.
Fetch the next digit (9) from the dividend, attach it to 401 and continue: 4019 / 802

Step 7:
802 can be fit into 4019 5 times, resulting in a remainder of 9.
The next digit of our result is 5. 
Result so far: 10745.0
Deduct 4010 from 4019 and we're left with 9.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 802

Advancing to step 8:
The number 802 fits into 92 0 times, leaving a remainder of 92.
The number 0 becomes the next digit in our result. 
Result so far: 107450.0
Subtracting 0 from 92 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 9:
The number 802 fits into 920 1 times, leaving a remainder of 118.
Write down 1 as next digit of the result. 
Result so far: 107450.1
The remainder is 118 after subtracting 802 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Going ahead to step 10:
1180 divided by 802 is 1 with a remainder of 378.
Use 1 as the next digit of our solution. 
Result so far: 107450.11
The remainder is 378 after subtracting 802 from 1180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

After the division, we end up with 107450.11 and a remainder of 0.378.
