We look at the division of 39225717 by 486 
We want to figure out the number of times 39225717 can be divided by 486.

Let's proceed to step 1:
When dividing 3 by 486, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 486

Advancing to step 2:
The number 486 fits into 39 0 times, leaving a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Fetch the next digit (2) from the dividend, attach it to 39 and continue: 392 / 486

Advancing to step 3:
The number 486 fits into 392 0 times, leaving a remainder of 392.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 392 after subtracting 0 from 392.
Take the next digit (2) from the dividend and append it to 392, then repeat: 3922 / 486

Going ahead to step 4:
3922 divided by 486 is 8 with a remainder of 34.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 34 after subtracting 3888 from 3922.
Take the next digit (5) from the dividend and append it to 34, then repeat: 345 / 486

Step 5:
The number 486 fits into 345 0 times, leaving a remainder of 345.
Put 0 as the next digit of the answer. 
Result so far: 80.0
Subtracting 0 from 345 leaves us with 345.
Grab the next digit (7) from the dividend, add it to 345, then carry on: 3457 / 486

On to step 6:
486 can be fit into 3457 7 times, resulting in a remainder of 55.
Put 7 as the next digit of the answer. 
Result so far: 807.0
Subtracting 3402 from 3457 leaves us with 55.
Fetch the next digit (1) from the dividend, attach it to 55 and continue: 551 / 486

Step 7:
486 can be fit into 551 1 times, resulting in a remainder of 65.
Put 1 as the next digit of the answer. 
Result so far: 8071.0
Deduct 486 from 551 and we're left with 65.
Take the next digit (7) from the dividend and append it to 65, then repeat: 657 / 486

Let's proceed to step 8:
486 goes into 657 1 times with a remainder of 171.
Record the quotient 1 as the next digit in the result. 
Result so far: 80711.0
If we take 486 away from 657, we end up with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Advancing to step 9:
486 can be fit into 1710 3 times, resulting in a remainder of 252.
The next digit of our result is 3. 
Result so far: 80711.3
The remainder is 252 after subtracting 1458 from 1710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Step 10:
2520 divided by 486 is 5 with a remainder of 90.
Use 5 as the next digit of our solution. 
Result so far: 80711.35
Deduct 2430 from 2520 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 11:
If we divide 900 by 486, we get 1 and a remainder of 414.
Record the quotient 1 as the next digit in the result. 
Result so far: 80711.351
If we take 486 away from 900, we end up with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

On to step 12:
The number 486 fits into 4140 8 times, leaving a remainder of 252.
Record the quotient 8 as the next digit in the result. 
Result so far: 80711.3518
If we subtract 3888 from 4140, we get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Advancing to step 13:
The number 486 fits into 2520 5 times, leaving a remainder of 90.
Write down 5 as next digit of the result. 
Result so far: 80711.35185
If we subtract 2430 from 2520, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 14:
The number 486 fits into 900 1 times, leaving a remainder of 414.
The number 1 becomes the next digit in our result. 
Result so far: 80711.351851
If we subtract 486 from 900, we get 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Going ahead to step 15:
The number 486 fits into 4140 8 times, leaving a remainder of 252.
Record the quotient 8 as the next digit in the result. 
Result so far: 80711.3518518
Deduct 3888 from 4140 and we're left with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

On to step 16:
2520 divided by 486 is 5 with a remainder of 90.
Use 5 as the next digit of our solution. 
Result so far: 80711.35185185
The remainder is 90 after subtracting 2430 from 2520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

The quotient of the division is 80711.35185185, and the remainder is 9e-08.
