We're dividing 637139 by 86 
Let's see how many times 86 fits into 637139.

Advancing to step 1:
6 divided by 86 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 86

Moving on to step 2:
If we divide 63 by 86, we get 0 and a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Bring next digit (7) of the dividend behind the 63 and repeat the process: 637 / 86

Let's proceed to step 3:
637 divided by 86 is 7 with a remainder of 35.
The next digit of our result is 7. 
Result so far: 7.0
If we take 602 away from 637, we end up with 35.
Bring next digit (1) of the dividend behind the 35 and repeat the process: 351 / 86

On to step 4:
The number 86 fits into 351 4 times, leaving a remainder of 7.
The next digit of our result is 4. 
Result so far: 74.0
Subtract 344 from 351 to get 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 86

Let's proceed to step 5:
The number 86 fits into 73 0 times, leaving a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 740.0
Subtracting 0 from 73 leaves us with 73.
Append the next digit (9) from the dividend to 73 and continue with: 739 / 86

On to step 6:
If we divide 739 by 86, we get 8 and a remainder of 51.
The number 8 becomes the next digit in our result. 
Result so far: 7408.0
Deduct 688 from 739 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 7:
510 divided by 86 is 5 with a remainder of 80.
Write down 5 as next digit of the result. 
Result so far: 7408.5
Subtract 430 from 510 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 8:
86 can be fit into 800 9 times, resulting in a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 7408.59
Subtract 774 from 800 to 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.

On to step 9:
86 can be fit into 260 3 times, resulting in a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 7408.593
If we subtract 258 from 260, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
20 divided by 86 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 7408.593
Subtracting 0 from 20 leaves us 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.

Step 11:
200 divided by 86 is 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 7408.59302
If we subtract 172 from 200, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 12:
86 can be fit into 280 3 times, resulting in a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 7408.593023
Subtracting 258 from 280 leaves us 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.

Advancing to step 13:
When dividing 220 by 86, we get 2 with a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 7408.5930232
If we subtract 172 from 220, we 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.

Moving on to step 14:
When dividing 480 by 86, we get 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 7408.59302325
The remainder is 50 after subtracting 430 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 7408.59302325 with a remaining 5e-08.
