Let's divide 674320 by 86
We want to divide 674320 by 86.

Going ahead to step 1:
6 divided by 86 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 86

Advancing to step 2:
When dividing 67 by 86, we get 0 with a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 67, we end up with 67.
Include the next digit (4) from the dividend after 67, then repeat: 674 / 86

Let's proceed to step 3:
The number 86 fits into 674 7 times, leaving a remainder of 72.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 602 from 674 and we're left with 72.
Bring next digit (3) of the dividend behind the 72 and repeat the process: 723 / 86

Advancing to step 4:
If we divide 723 by 86, we get 8 and a remainder of 35.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
Subtract 688 from 723 to get 35.
Take the next digit (2) from the dividend and append it to 35, then repeat: 352 / 86

Step 5:
If we divide 352 by 86, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 784.0
The remainder is 8 after subtracting 344 from 352.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 86

Advancing to step 6:
The number 86 fits into 80 0 times, leaving a remainder of 80.
The next digit of our result is 0. 
Result so far: 7840.0
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 7:
If we divide 800 by 86, we get 9 and a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 7840.9
If we subtract 774 from 800, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 8:
When dividing 260 by 86, we get 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 7840.93
If we take 258 away from 260, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
When dividing 20 by 86, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 7840.93
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
86 can be fit into 200 2 times, resulting in a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 7840.9302
If we take 172 away from 200, we end up with 28.
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 11:
The number 86 fits into 280 3 times, leaving a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 7840.93023
If we take 258 away from 280, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 12:
86 can be fit into 220 2 times, resulting in a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 7840.930232
Subtract 172 from 220 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 13:
86 can be fit into 480 5 times, resulting in a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 7840.9302325
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.

Moving on to step 14:
500 divided by 86 is 5 with a remainder of 70.
The next digit of our result is 5. 
Result so far: 7840.93023255
If we take 430 away from 500, we end up 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 7840.93023255 and a remainder of 7e-08.
