We're dividing 54978648 by 863 
Our goal is to divide 54978648 by 863.

Moving on to step 1:
The number 863 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 863

Step 2:
863 can be fit into 54 0 times, resulting in a remainder of 54.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Grab the next digit (9) from the dividend, add it to 54, then carry on: 549 / 863

Advancing to step 3:
863 goes into 549 0 times with a remainder of 549.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 549 to get 549.
Bring next digit (7) of the dividend behind the 549 and repeat the process: 5497 / 863

Moving on to step 4:
If we divide 5497 by 863, we get 6 and a remainder of 319.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 5178 from 5497 leaves us with 319.
Bring next digit (8) of the dividend behind the 319 and repeat the process: 3198 / 863

Going ahead to step 5:
If we divide 3198 by 863, we get 3 and a remainder of 609.
Put 3 as the next digit of the answer. 
Result so far: 63.0
Subtract 2589 from 3198 to get 609.
Append the next digit (6) from the dividend to 609 and continue with: 6096 / 863

Let's proceed to step 6:
863 can be fit into 6096 7 times, resulting in a remainder of 55.
The next digit of our result is 7. 
Result so far: 637.0
The remainder is 55 after subtracting 6041 from 6096.
Grab the next digit (4) from the dividend, add it to 55, then carry on: 554 / 863

Advancing to step 7:
863 can be fit into 554 0 times, resulting in a remainder of 554.
The number 0 becomes the next digit in our result. 
Result so far: 6370.0
If we take 0 away from 554, we end up with 554.
Append the next digit (8) from the dividend to 554 and continue with: 5548 / 863

Advancing to step 8:
The number 863 fits into 5548 6 times, leaving a remainder of 370.
The number 6 becomes the next digit in our result. 
Result so far: 63706.0
If we subtract 5178 from 5548, 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.

Step 9:
The number 863 fits into 3700 4 times, leaving a remainder of 248.
Record the quotient 4 as the next digit in the result. 
Result so far: 63706.4
If we subtract 3452 from 3700, we get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Step 10:
863 goes into 2480 2 times with a remainder of 754.
The number 2 becomes the next digit in our result. 
Result so far: 63706.42
Deduct 1726 from 2480 and we're left with 754.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7540, and continue the process.

Going ahead to step 11:
7540 divided by 863 is 8 with a remainder of 636.
The next digit of our result is 8. 
Result so far: 63706.428
Subtract 6904 from 7540 to get 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Going ahead to step 12:
When dividing 6360 by 863, we get 7 with a remainder of 319.
The next digit of our result is 7. 
Result so far: 63706.4287
Subtracting 6041 from 6360 leaves us with 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Going ahead to step 13:
3190 divided by 863 is 3 with a remainder of 601.
Put 3 as the next digit of the answer. 
Result so far: 63706.42873
Deduct 2589 from 3190 and we're left with 601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

Advancing to step 14:
When dividing 6010 by 863, we get 6 with a remainder of 832.
Record the quotient 6 as the next digit in the result. 
Result so far: 63706.428736
Subtracting 5178 from 6010 leaves us with 832.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

Moving on to step 15:
The number 863 fits into 8320 9 times, leaving a remainder of 553.
The number 9 becomes the next digit in our result. 
Result so far: 63706.4287369
Subtracting 7767 from 8320 leaves us with 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

Step 16:
863 can be fit into 5530 6 times, resulting in a remainder of 352.
The number 6 becomes the next digit in our result. 
Result so far: 63706.42873696
If we subtract 5178 from 5530, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

The final result is 63706.42873696 with a remainder of 3.52e-07.
