We look at the division of 3930572 by 489 
We want to figure out the number of times 3930572 can be divided by 489.

Advancing to step 1:
489 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 489

Step 2:
When dividing 39 by 489, we get 0 with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Fetch the next digit (3) from the dividend, attach it to 39 and continue: 393 / 489

Going ahead to step 3:
The number 489 fits into 393 0 times, leaving a remainder of 393.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 393, we end up with 393.
Take the next digit (0) from the dividend and append it to 393, then repeat: 3930 / 489

On to step 4:
When dividing 3930 by 489, we get 8 with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 3912 from 3930 and we're left with 18.
Bring next digit (5) of the dividend behind the 18 and repeat the process: 185 / 489

Going ahead to step 5:
489 can be fit into 185 0 times, resulting in a remainder of 185.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
If we subtract 0 from 185, we get 185.
Grab the next digit (7) from the dividend, add it to 185, then carry on: 1857 / 489

Going ahead to step 6:
489 can be fit into 1857 3 times, resulting in a remainder of 390.
Record the quotient 3 as the next digit in the result. 
Result so far: 803.0
If we subtract 1467 from 1857, we get 390.
Fetch the next digit (2) from the dividend, attach it to 390 and continue: 3902 / 489

Advancing to step 7:
3902 divided by 489 is 7 with a remainder of 479.
Put 7 as the next digit of the answer. 
Result so far: 8037.0
The remainder is 479 after subtracting 3423 from 3902.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Step 8:
When dividing 4790 by 489, we get 9 with a remainder of 389.
Use 9 as the next digit of our solution. 
Result so far: 8037.9
Deduct 4401 from 4790 and we're left with 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Advancing to step 9:
489 goes into 3890 7 times with a remainder of 467.
Write down 7 as next digit of the result. 
Result so far: 8037.97
If we take 3423 away from 3890, we end up with 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

On to step 10:
If we divide 4670 by 489, we get 9 and a remainder of 269.
Use 9 as the next digit of our solution. 
Result so far: 8037.979
Subtracting 4401 from 4670 leaves us with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Step 11:
When dividing 2690 by 489, we get 5 with a remainder of 245.
The number 5 becomes the next digit in our result. 
Result so far: 8037.9795
The remainder is 245 after subtracting 2445 from 2690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

On to step 12:
489 can be fit into 2450 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 8037.97955
Subtract 2445 from 2450 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 8037.97955 and a remainder of 5e-06.
