We look at the division of 630604 by 86 
Let's see how many times 86 fits into 630604.

Step 1:
6 divided by 86 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 86

Let's proceed to step 2:
86 goes into 63 0 times with a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Include the next digit (0) from the dividend after 63, then repeat: 630 / 86

Advancing to step 3:
When dividing 630 by 86, we get 7 with a remainder of 28.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 602 away from 630, we end up with 28.
Fetch the next digit (6) from the dividend, attach it to 28 and continue: 286 / 86

Let's proceed to step 4:
86 goes into 286 3 times with a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 73.0
Subtract 258 from 286 to get 28.
Bring next digit (0) of the dividend behind the 28 and repeat the process: 280 / 86

On to step 5:
280 divided by 86 is 3 with a remainder of 22.
The next digit of our result is 3. 
Result so far: 733.0
If we take 258 away from 280, we end up with 22.
Bring next digit (4) of the dividend behind the 22 and repeat the process: 224 / 86

Going ahead to step 6:
224 divided by 86 is 2 with a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 7332.0
Subtract 172 from 224 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 7:
520 divided by 86 is 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 7332.6
Subtracting 516 from 520 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
The number 86 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 7332.6
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
86 can be fit into 400 4 times, resulting in a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 7332.604
Deduct 344 from 400 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 10:
When dividing 560 by 86, we get 6 with a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 7332.6046
Subtract 516 from 560 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 11:
When dividing 440 by 86, we get 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 7332.60465
The remainder is 10 after subtracting 430 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
86 goes into 100 1 times with a remainder of 14.
The next digit of our result is 1. 
Result so far: 7332.604651
If we subtract 86 from 100, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 13:
When dividing 140 by 86, we get 1 with a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 7332.6046511
Subtracting 86 from 140 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

After the division, we end up with 7332.6046511 and a remainder of 5.4e-07.
