We're dividing 18735369 by 863 
Our goal is to divide 18735369 by 863.

Step 1:
1 divided by 863 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 863

Advancing to step 2:
863 can be fit into 18 0 times, resulting in a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Append the next digit (7) from the dividend to 18 and continue with: 187 / 863

Let's proceed to step 3:
The number 863 fits into 187 0 times, leaving a remainder of 187.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 187 and we're left with 187.
Include the next digit (3) from the dividend after 187, then repeat: 1873 / 863

Let's proceed to step 4:
When dividing 1873 by 863, we get 2 with a remainder of 147.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 1726 away from 1873, we end up with 147.
Fetch the next digit (5) from the dividend, attach it to 147 and continue: 1475 / 863

Let's proceed to step 5:
863 goes into 1475 1 times with a remainder of 612.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtract 863 from 1475 to get 612.
Include the next digit (3) from the dividend after 612, then repeat: 6123 / 863

Advancing to step 6:
If we divide 6123 by 863, we get 7 and a remainder of 82.
Use 7 as the next digit of our solution. 
Result so far: 217.0
Deduct 6041 from 6123 and we're left with 82.
Append the next digit (6) from the dividend to 82 and continue with: 826 / 863

Advancing to step 7:
826 divided by 863 is 0 with a remainder of 826.
Record the quotient 0 as the next digit in the result. 
Result so far: 2170.0
Subtracting 0 from 826 leaves us with 826.
Grab the next digit (9) from the dividend, add it to 826, then carry on: 8269 / 863

On to step 8:
If we divide 8269 by 863, we get 9 and a remainder of 502.
Use 9 as the next digit of our solution. 
Result so far: 21709.0
Subtract 7767 from 8269 to get 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Going ahead to step 9:
863 goes into 5020 5 times with a remainder of 705.
The next digit of our result is 5. 
Result so far: 21709.5
If we subtract 4315 from 5020, we get 705.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7050, and continue the process.

Step 10:
863 goes into 7050 8 times with a remainder of 146.
Write down 8 as next digit of the result. 
Result so far: 21709.58
If we subtract 6904 from 7050, we get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Moving on to step 11:
The number 863 fits into 1460 1 times, leaving a remainder of 597.
Use 1 as the next digit of our solution. 
Result so far: 21709.581
The remainder is 597 after subtracting 863 from 1460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5970, and continue the process.

Step 12:
If we divide 5970 by 863, we get 6 and a remainder of 792.
Use 6 as the next digit of our solution. 
Result so far: 21709.5816
Subtracting 5178 from 5970 leaves us with 792.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7920, and continue the process.

Going ahead to step 13:
863 can be fit into 7920 9 times, resulting in a remainder of 153.
Use 9 as the next digit of our solution. 
Result so far: 21709.58169
Deduct 7767 from 7920 and we're left with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

On to step 14:
1530 divided by 863 is 1 with a remainder of 667.
Put 1 as the next digit of the answer. 
Result so far: 21709.581691
The remainder is 667 after subtracting 863 from 1530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6670, and continue the process.

Going ahead to step 15:
863 goes into 6670 7 times with a remainder of 629.
The next digit of our result is 7. 
Result so far: 21709.5816917
Deduct 6041 from 6670 and we're left with 629.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6290, and continue the process.

On to step 16:
When dividing 6290 by 863, we get 7 with a remainder of 249.
The number 7 becomes the next digit in our result. 
Result so far: 21709.58169177
If we take 6041 away from 6290, we end up with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

After the division, we end up with 21709.58169177 and a remainder of 2.49e-07.
