We look at the division of 39870654 by 411 
Let's see how many times 411 fits into 39870654.

Step 1:
When dividing 3 by 411, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 411

Advancing to step 2:
When dividing 39 by 411, we get 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Append the next digit (8) from the dividend to 39 and continue with: 398 / 411

Advancing to step 3:
When dividing 398 by 411, we get 0 with a remainder of 398.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 398 to get 398.
Append the next digit (7) from the dividend to 398 and continue with: 3987 / 411

Going ahead to step 4:
411 can be fit into 3987 9 times, resulting in a remainder of 288.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 3699 away from 3987, we end up with 288.
Fetch the next digit (0) from the dividend, attach it to 288 and continue: 2880 / 411

Moving on to step 5:
When dividing 2880 by 411, we get 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 97.0
The remainder is 3 after subtracting 2877 from 2880.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 411

Advancing to step 6:
36 divided by 411 is 0 with a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 970.0
The remainder is 36 after subtracting 0 from 36.
Grab the next digit (5) from the dividend, add it to 36, then carry on: 365 / 411

Let's proceed to step 7:
If we divide 365 by 411, we get 0 and a remainder of 365.
The next digit of our result is 0. 
Result so far: 9700.0
If we take 0 away from 365, we end up with 365.
Append the next digit (4) from the dividend to 365 and continue with: 3654 / 411

Let's proceed to step 8:
411 goes into 3654 8 times with a remainder of 366.
Put 8 as the next digit of the answer. 
Result so far: 97008.0
The remainder is 366 after subtracting 3288 from 3654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Going ahead to step 9:
3660 divided by 411 is 8 with a remainder of 372.
Write down 8 as next digit of the result. 
Result so far: 97008.8
Deduct 3288 from 3660 and we're left with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Step 10:
411 can be fit into 3720 9 times, resulting in a remainder of 21.
The next digit of our result is 9. 
Result so far: 97008.89
The remainder is 21 after subtracting 3699 from 3720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 11:
If we divide 210 by 411, we get 0 and a remainder of 210.
The next digit of our result is 0. 
Result so far: 97008.89
Deduct 0 from 210 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 12:
2100 divided by 411 is 5 with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 97008.8905
The remainder is 45 after subtracting 2055 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 13:
If we divide 450 by 411, we get 1 and a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 97008.89051
The remainder is 39 after subtracting 411 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 14:
411 can be fit into 390 0 times, resulting in a remainder of 390.
Record the quotient 0 as the next digit in the result. 
Result so far: 97008.89051
Subtract 0 from 390 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 15:
If we divide 3900 by 411, we get 9 and a remainder of 201.
The number 9 becomes the next digit in our result. 
Result so far: 97008.8905109
If we subtract 3699 from 3900, we get 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Moving on to step 16:
If we divide 2010 by 411, we get 4 and a remainder of 366.
Write down 4 as next digit of the result. 
Result so far: 97008.89051094
Subtract 1644 from 2010 to get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

The final outcome is 97008.89051094, with a leftover of 3.66e-07.
