54886371 divided by 840 
We want to divide 54886371 by 840.

Going ahead to step 1:
If we divide 5 by 840, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 840

Going ahead to step 2:
When dividing 54 by 840, we get 0 with a remainder of 54.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Include the next digit (8) from the dividend after 54, then repeat: 548 / 840

On to step 3:
If we divide 548 by 840, we get 0 and a remainder of 548.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 548 leaves us with 548.
Grab the next digit (8) from the dividend, add it to 548, then carry on: 5488 / 840

Let's proceed to step 4:
840 goes into 5488 6 times with a remainder of 448.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 5040 from 5488, we get 448.
Append the next digit (6) from the dividend to 448 and continue with: 4486 / 840

Let's proceed to step 5:
4486 divided by 840 is 5 with a remainder of 286.
Use 5 as the next digit of our solution. 
Result so far: 65.0
Deduct 4200 from 4486 and we're left with 286.
Include the next digit (3) from the dividend after 286, then repeat: 2863 / 840

Moving on to step 6:
840 goes into 2863 3 times with a remainder of 343.
Put 3 as the next digit of the answer. 
Result so far: 653.0
If we subtract 2520 from 2863, we get 343.
Grab the next digit (7) from the dividend, add it to 343, then carry on: 3437 / 840

On to step 7:
When dividing 3437 by 840, we get 4 with a remainder of 77.
The next digit of our result is 4. 
Result so far: 6534.0
Subtracting 3360 from 3437 leaves us with 77.
Bring next digit (1) of the dividend behind the 77 and repeat the process: 771 / 840

Let's proceed to step 8:
840 can be fit into 771 0 times, resulting in a remainder of 771.
The next digit of our result is 0. 
Result so far: 65340.0
If we take 0 away from 771, we end up with 771.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7710, and continue the process.

On to step 9:
When dividing 7710 by 840, we get 9 with a remainder of 150.
The number 9 becomes the next digit in our result. 
Result so far: 65340.9
The remainder is 150 after subtracting 7560 from 7710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 10:
840 can be fit into 1500 1 times, resulting in a remainder of 660.
Use 1 as the next digit of our solution. 
Result so far: 65340.91
Subtracting 840 from 1500 leaves us with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Advancing to step 11:
When dividing 6600 by 840, we get 7 with a remainder of 720.
Use 7 as the next digit of our solution. 
Result so far: 65340.917
Subtract 5880 from 6600 to get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Step 12:
840 can be fit into 7200 8 times, resulting in a remainder of 480.
Record the quotient 8 as the next digit in the result. 
Result so far: 65340.9178
If we take 6720 away from 7200, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 13:
840 goes into 4800 5 times with a remainder of 600.
The next digit of our result is 5. 
Result so far: 65340.91785
Subtract 4200 from 4800 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 14:
840 goes into 6000 7 times with a remainder of 120.
Put 7 as the next digit of the answer. 
Result so far: 65340.917857
If we subtract 5880 from 6000, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 15:
The number 840 fits into 1200 1 times, leaving a remainder of 360.
Use 1 as the next digit of our solution. 
Result so far: 65340.9178571
Subtract 840 from 1200 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 16:
The number 840 fits into 3600 4 times, leaving a remainder of 240.
Write down 4 as next digit of the result. 
Result so far: 65340.91785714
Subtract 3360 from 3600 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

After the division, we end up with 65340.91785714 and a remainder of 2.4e-07.
