42454172 divided by 863 
We want to divide 42454172 by 863.

Moving on to step 1:
The number 863 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 863

Advancing to step 2:
42 divided by 863 is 0 with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Append the next digit (4) from the dividend to 42 and continue with: 424 / 863

Step 3:
If we divide 424 by 863, we get 0 and a remainder of 424.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 424 to get 424.
Fetch the next digit (5) from the dividend, attach it to 424 and continue: 4245 / 863

Step 4:
When dividing 4245 by 863, we get 4 with a remainder of 793.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 3452 from 4245 leaves us with 793.
Grab the next digit (4) from the dividend, add it to 793, then carry on: 7934 / 863

Going ahead to step 5:
7934 divided by 863 is 9 with a remainder of 167.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
Deduct 7767 from 7934 and we're left with 167.
Include the next digit (1) from the dividend after 167, then repeat: 1671 / 863

Going ahead to step 6:
1671 divided by 863 is 1 with a remainder of 808.
Put 1 as the next digit of the answer. 
Result so far: 491.0
If we take 863 away from 1671, we end up with 808.
Append the next digit (7) from the dividend to 808 and continue with: 8087 / 863

Step 7:
When dividing 8087 by 863, we get 9 with a remainder of 320.
Use 9 as the next digit of our solution. 
Result so far: 4919.0
If we take 7767 away from 8087, we end up with 320.
Fetch the next digit (2) from the dividend, attach it to 320 and continue: 3202 / 863

Going ahead to step 8:
When dividing 3202 by 863, we get 3 with a remainder of 613.
Write down 3 as next digit of the result. 
Result so far: 49193.0
Subtracting 2589 from 3202 leaves us with 613.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6130, and continue the process.

On to step 9:
863 goes into 6130 7 times with a remainder of 89.
Put 7 as the next digit of the answer. 
Result so far: 49193.7
If we subtract 6041 from 6130, we get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Going ahead to step 10:
The number 863 fits into 890 1 times, leaving a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 49193.71
If we subtract 863 from 890, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 11:
If we divide 270 by 863, we get 0 and a remainder of 270.
Put 0 as the next digit of the answer. 
Result so far: 49193.71
The remainder is 270 after subtracting 0 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 12:
The number 863 fits into 2700 3 times, leaving a remainder of 111.
Write down 3 as next digit of the result. 
Result so far: 49193.7103
Subtracting 2589 from 2700 leaves us with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Moving on to step 13:
1110 divided by 863 is 1 with a remainder of 247.
The next digit of our result is 1. 
Result so far: 49193.71031
Subtract 863 from 1110 to get 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Moving on to step 14:
If we divide 2470 by 863, we get 2 and a remainder of 744.
Write down 2 as next digit of the result. 
Result so far: 49193.710312
If we subtract 1726 from 2470, we get 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

Step 15:
The number 863 fits into 7440 8 times, leaving a remainder of 536.
Put 8 as the next digit of the answer. 
Result so far: 49193.7103128
Deduct 6904 from 7440 and we're left with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Going ahead to step 16:
When dividing 5360 by 863, we get 6 with a remainder of 182.
Write down 6 as next digit of the result. 
Result so far: 49193.71031286
The remainder is 182 after subtracting 5178 from 5360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

The final result is 49193.71031286 with a remainder of 1.82e-07.
