54379968 ÷ 861 
We want to divide 54379968 by 861.

On to step 1:
861 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 861

Going ahead to step 2:
861 goes into 54 0 times with a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 54 after subtracting 0 from 54.
Grab the next digit (3) from the dividend, add it to 54, then carry on: 543 / 861

Moving on to step 3:
If we divide 543 by 861, we get 0 and a remainder of 543.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 543, we end up with 543.
Fetch the next digit (7) from the dividend, attach it to 543 and continue: 5437 / 861

Going ahead to step 4:
The number 861 fits into 5437 6 times, leaving a remainder of 271.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 5166 from 5437 leaves us with 271.
Include the next digit (9) from the dividend after 271, then repeat: 2719 / 861

Advancing to step 5:
If we divide 2719 by 861, we get 3 and a remainder of 136.
Use 3 as the next digit of our solution. 
Result so far: 63.0
If we subtract 2583 from 2719, we get 136.
Append the next digit (9) from the dividend to 136 and continue with: 1369 / 861

Going ahead to step 6:
If we divide 1369 by 861, we get 1 and a remainder of 508.
Put 1 as the next digit of the answer. 
Result so far: 631.0
If we take 861 away from 1369, we end up with 508.
Take the next digit (6) from the dividend and append it to 508, then repeat: 5086 / 861

Step 7:
861 can be fit into 5086 5 times, resulting in a remainder of 781.
Write down 5 as next digit of the result. 
Result so far: 6315.0
Subtracting 4305 from 5086 leaves us with 781.
Bring next digit (8) of the dividend behind the 781 and repeat the process: 7818 / 861

Advancing to step 8:
If we divide 7818 by 861, we get 9 and a remainder of 69.
Put 9 as the next digit of the answer. 
Result so far: 63159.0
If we take 7749 away from 7818, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 9:
When dividing 690 by 861, we get 0 with a remainder of 690.
Use 0 as the next digit of our solution. 
Result so far: 63159.0
Subtracting 0 from 690 leaves us with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Going ahead to step 10:
The number 861 fits into 6900 8 times, leaving a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 63159.08
Subtract 6888 from 6900 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
861 can be fit into 120 0 times, resulting in a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 63159.08
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 12:
861 goes into 1200 1 times with a remainder of 339.
Write down 1 as next digit of the result. 
Result so far: 63159.0801
If we subtract 861 from 1200, we get 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

On to step 13:
3390 divided by 861 is 3 with a remainder of 807.
The next digit of our result is 3. 
Result so far: 63159.08013
Subtract 2583 from 3390 to get 807.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8070, and continue the process.

Let's proceed to step 14:
861 can be fit into 8070 9 times, resulting in a remainder of 321.
Record the quotient 9 as the next digit in the result. 
Result so far: 63159.080139
Subtract 7749 from 8070 to get 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Moving on to step 15:
861 can be fit into 3210 3 times, resulting in a remainder of 627.
Use 3 as the next digit of our solution. 
Result so far: 63159.0801393
If we take 2583 away from 3210, we end up with 627.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6270, and continue the process.

Let's proceed to step 16:
861 goes into 6270 7 times with a remainder of 243.
Record the quotient 7 as the next digit in the result. 
Result so far: 63159.08013937
Subtracting 6027 from 6270 leaves us with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

The quotient of the division is 63159.08013937, and the remainder is 2.43e-07.
