We look at the division of 39702579 by 485 
We want to divide 39702579 by 485.

On to step 1:
485 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 485

Let's proceed to step 2:
485 can be fit into 39 0 times, resulting in a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Append the next digit (7) from the dividend to 39 and continue with: 397 / 485

On to step 3:
When dividing 397 by 485, we get 0 with a remainder of 397.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 397 to get 397.
Append the next digit (0) from the dividend to 397 and continue with: 3970 / 485

Moving on to step 4:
485 goes into 3970 8 times with a remainder of 90.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 3880 from 3970, we get 90.
Grab the next digit (2) from the dividend, add it to 90, then carry on: 902 / 485

Step 5:
When dividing 902 by 485, we get 1 with a remainder of 417.
Write down 1 as next digit of the result. 
Result so far: 81.0
If we subtract 485 from 902, we get 417.
Take the next digit (5) from the dividend and append it to 417, then repeat: 4175 / 485

Let's proceed to step 6:
When dividing 4175 by 485, we get 8 with a remainder of 295.
The number 8 becomes the next digit in our result. 
Result so far: 818.0
If we take 3880 away from 4175, we end up with 295.
Include the next digit (7) from the dividend after 295, then repeat: 2957 / 485

Advancing to step 7:
If we divide 2957 by 485, we get 6 and a remainder of 47.
Record the quotient 6 as the next digit in the result. 
Result so far: 8186.0
If we subtract 2910 from 2957, we get 47.
Append the next digit (9) from the dividend to 47 and continue with: 479 / 485

On to step 8:
485 goes into 479 0 times with a remainder of 479.
Put 0 as the next digit of the answer. 
Result so far: 81860.0
Deduct 0 from 479 and we're left with 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Step 9:
485 can be fit into 4790 9 times, resulting in a remainder of 425.
Write down 9 as next digit of the result. 
Result so far: 81860.9
Deduct 4365 from 4790 and we're left with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

On to step 10:
The number 485 fits into 4250 8 times, leaving a remainder of 370.
The number 8 becomes the next digit in our result. 
Result so far: 81860.98
If we subtract 3880 from 4250, we get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Let's proceed to step 11:
485 goes into 3700 7 times with a remainder of 305.
The number 7 becomes the next digit in our result. 
Result so far: 81860.987
Subtract 3395 from 3700 to get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Moving on to step 12:
The number 485 fits into 3050 6 times, leaving a remainder of 140.
The next digit of our result is 6. 
Result so far: 81860.9876
The remainder is 140 after subtracting 2910 from 3050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 13:
1400 divided by 485 is 2 with a remainder of 430.
The next digit of our result is 2. 
Result so far: 81860.98762
Subtracting 970 from 1400 leaves us with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Going ahead to step 14:
If we divide 4300 by 485, we get 8 and a remainder of 420.
The number 8 becomes the next digit in our result. 
Result so far: 81860.987628
Subtract 3880 from 4300 to get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 15:
4200 divided by 485 is 8 with a remainder of 320.
The next digit of our result is 8. 
Result so far: 81860.9876288
Subtracting 3880 from 4200 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The quotient of the division is 81860.9876288, and the remainder is 3.2e-06.
