We look at the division of 674202 by 86 
Let's see how many times 86 fits into 674202.

On to step 1:
When dividing 6 by 86, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 86

Going ahead to step 2:
If we divide 67 by 86, we get 0 and a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 67 after subtracting 0 from 67.
Grab the next digit (4) from the dividend, add it to 67, then carry on: 674 / 86

Going ahead to step 3:
86 can be fit into 674 7 times, resulting in a remainder of 72.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 602 away from 674, we end up with 72.
Grab the next digit (2) from the dividend, add it to 72, then carry on: 722 / 86

Advancing to step 4:
86 can be fit into 722 8 times, resulting in a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
Subtract 688 from 722 to get 34.
Take the next digit (0) from the dividend and append it to 34, then repeat: 340 / 86

On to step 5:
The number 86 fits into 340 3 times, leaving a remainder of 82.
The next digit of our result is 3. 
Result so far: 783.0
Subtract 258 from 340 to get 82.
Fetch the next digit (2) from the dividend, attach it to 82 and continue: 822 / 86

On to step 6:
When dividing 822 by 86, we get 9 with a remainder of 48.
Put 9 as the next digit of the answer. 
Result so far: 7839.0
The remainder is 48 after subtracting 774 from 822.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 7:
86 goes into 480 5 times with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 7839.5
Subtract 430 from 480 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 8:
86 can be fit into 500 5 times, resulting in a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 7839.55
Deduct 430 from 500 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 7839.55 and a remainder of 0.07.
