We look at the division of 730221 by 86 
We want to divide 730221 by 86.

Going ahead to step 1:
86 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 86

Let's proceed to step 2:
86 can be fit into 73 0 times, resulting in a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 73, we end up with 73.
Fetch the next digit (0) from the dividend, attach it to 73 and continue: 730 / 86

Advancing to step 3:
86 goes into 730 8 times with a remainder of 42.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 688 from 730, we get 42.
Fetch the next digit (2) from the dividend, attach it to 42 and continue: 422 / 86

On to step 4:
86 can be fit into 422 4 times, resulting in a remainder of 78.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
If we subtract 344 from 422, we get 78.
Fetch the next digit (2) from the dividend, attach it to 78 and continue: 782 / 86

Let's proceed to step 5:
782 divided by 86 is 9 with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 849.0
Subtracting 774 from 782 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 86

Advancing to step 6:
81 divided by 86 is 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 8490.0
If we subtract 0 from 81, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 7:
The number 86 fits into 810 9 times, leaving a remainder of 36.
Put 9 as the next digit of the answer. 
Result so far: 8490.9
If we subtract 774 from 810, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 8:
When dividing 360 by 86, we get 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 8490.94
Deduct 344 from 360 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
86 can be fit into 160 1 times, resulting in a remainder of 74.
Use 1 as the next digit of our solution. 
Result so far: 8490.941
If we subtract 86 from 160, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 10:
If we divide 740 by 86, we get 8 and a remainder of 52.
The next digit of our result is 8. 
Result so far: 8490.9418
The remainder is 52 after subtracting 688 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 11:
86 can be fit into 520 6 times, resulting in a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 8490.94186
If we take 516 away from 520, we end up 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.

Going ahead to step 12:
86 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 8490.94186
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 13:
The number 86 fits into 400 4 times, leaving a remainder of 56.
The next digit of our result is 4. 
Result so far: 8490.9418604
If we subtract 344 from 400, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 14:
If we divide 560 by 86, we get 6 and a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 8490.94186046
If we take 516 away from 560, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final result is 8490.94186046 with a remainder of 4.4e-08.
