We're dividing 80569637 by 399 
Our goal is to divide 80569637 by 399.

Moving on to step 1:
The number 399 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 399

Step 2:
399 can be fit into 80 0 times, resulting in a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Append the next digit (5) from the dividend to 80 and continue with: 805 / 399

Moving on to step 3:
399 can be fit into 805 2 times, resulting in a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 798 away from 805, we end up with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 399

Moving on to step 4:
The number 399 fits into 76 0 times, leaving a remainder of 76.
The next digit of our result is 0. 
Result so far: 20.0
Deduct 0 from 76 and we're left with 76.
Take the next digit (9) from the dividend and append it to 76, then repeat: 769 / 399

On to step 5:
399 can be fit into 769 1 times, resulting in a remainder of 370.
Put 1 as the next digit of the answer. 
Result so far: 201.0
Subtract 399 from 769 to get 370.
Fetch the next digit (6) from the dividend, attach it to 370 and continue: 3706 / 399

Let's proceed to step 6:
399 goes into 3706 9 times with a remainder of 115.
The next digit of our result is 9. 
Result so far: 2019.0
If we take 3591 away from 3706, we end up with 115.
Grab the next digit (3) from the dividend, add it to 115, then carry on: 1153 / 399

Let's proceed to step 7:
1153 divided by 399 is 2 with a remainder of 355.
Record the quotient 2 as the next digit in the result. 
Result so far: 20192.0
If we subtract 798 from 1153, we get 355.
Append the next digit (7) from the dividend to 355 and continue with: 3557 / 399

Going ahead to step 8:
If we divide 3557 by 399, we get 8 and a remainder of 365.
Put 8 as the next digit of the answer. 
Result so far: 201928.0
Subtract 3192 from 3557 to get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Advancing to step 9:
When dividing 3650 by 399, we get 9 with a remainder of 59.
The number 9 becomes the next digit in our result. 
Result so far: 201928.9
If we take 3591 away from 3650, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 10:
399 can be fit into 590 1 times, resulting in a remainder of 191.
Record the quotient 1 as the next digit in the result. 
Result so far: 201928.91
Subtracting 399 from 590 leaves us with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

On to step 11:
399 can be fit into 1910 4 times, resulting in a remainder of 314.
The next digit of our result is 4. 
Result so far: 201928.914
Subtract 1596 from 1910 to get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Let's proceed to step 12:
3140 divided by 399 is 7 with a remainder of 347.
The next digit of our result is 7. 
Result so far: 201928.9147
Subtracting 2793 from 3140 leaves us with 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Moving on to step 13:
3470 divided by 399 is 8 with a remainder of 278.
Record the quotient 8 as the next digit in the result. 
Result so far: 201928.91478
If we take 3192 away from 3470, we end up with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Going ahead to step 14:
When dividing 2780 by 399, we get 6 with a remainder of 386.
Write down 6 as next digit of the result. 
Result so far: 201928.914786
If we subtract 2394 from 2780, we get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Step 15:
3860 divided by 399 is 9 with a remainder of 269.
Write down 9 as next digit of the result. 
Result so far: 201928.9147869
If we take 3591 away from 3860, we end up 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.

Let's proceed to step 16:
If we divide 2690 by 399, we get 6 and a remainder of 296.
Write down 6 as next digit of the result. 
Result so far: 201928.91478696
If we subtract 2394 from 2690, we get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

After the division, we end up with 201928.91478696 and a remainder of 2.96e-07.
