We're dividing 55223946 by 840 
Let's see how many times 840 fits into 55223946.

On to step 1:
5 divided by 840 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 840

Let's proceed to step 2:
840 can be fit into 55 0 times, resulting in a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Fetch the next digit (2) from the dividend, attach it to 55 and continue: 552 / 840

On to step 3:
The number 840 fits into 552 0 times, leaving a remainder of 552.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 552 to get 552.
Grab the next digit (2) from the dividend, add it to 552, then carry on: 5522 / 840

Advancing to step 4:
840 can be fit into 5522 6 times, resulting in a remainder of 482.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 482 after subtracting 5040 from 5522.
Include the next digit (3) from the dividend after 482, then repeat: 4823 / 840

Advancing to step 5:
If we divide 4823 by 840, we get 5 and a remainder of 623.
The number 5 becomes the next digit in our result. 
Result so far: 65.0
Deduct 4200 from 4823 and we're left with 623.
Bring next digit (9) of the dividend behind the 623 and repeat the process: 6239 / 840

On to step 6:
If we divide 6239 by 840, we get 7 and a remainder of 359.
The next digit of our result is 7. 
Result so far: 657.0
The remainder is 359 after subtracting 5880 from 6239.
Include the next digit (4) from the dividend after 359, then repeat: 3594 / 840

Advancing to step 7:
3594 divided by 840 is 4 with a remainder of 234.
Put 4 as the next digit of the answer. 
Result so far: 6574.0
If we subtract 3360 from 3594, we get 234.
Take the next digit (6) from the dividend and append it to 234, then repeat: 2346 / 840

On to step 8:
840 can be fit into 2346 2 times, resulting in a remainder of 666.
Write down 2 as next digit of the result. 
Result so far: 65742.0
Subtracting 1680 from 2346 leaves us with 666.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6660, and continue the process.

Advancing to step 9:
When dividing 6660 by 840, we get 7 with a remainder of 780.
Use 7 as the next digit of our solution. 
Result so far: 65742.7
Subtract 5880 from 6660 to get 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Moving on to step 10:
840 goes into 7800 9 times with a remainder of 240.
Record the quotient 9 as the next digit in the result. 
Result so far: 65742.79
If we take 7560 away from 7800, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 11:
840 goes into 2400 2 times with a remainder of 720.
Record the quotient 2 as the next digit in the result. 
Result so far: 65742.792
Deduct 1680 from 2400 and we're left with 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:
If we divide 7200 by 840, we get 8 and a remainder of 480.
The number 8 becomes the next digit in our result. 
Result so far: 65742.7928
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.

Moving on to step 13:
If we divide 4800 by 840, we get 5 and a remainder of 600.
Record the quotient 5 as the next digit in the result. 
Result so far: 65742.79285
The remainder is 600 after subtracting 4200 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

On to step 14:
840 goes into 6000 7 times with a remainder of 120.
Record the quotient 7 as the next digit in the result. 
Result so far: 65742.792857
If we take 5880 away from 6000, we end up 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.

Moving on to step 15:
If we divide 1200 by 840, we get 1 and a remainder of 360.
The next digit of our result is 1. 
Result so far: 65742.7928571
Subtracting 840 from 1200 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 16:
If we divide 3600 by 840, we get 4 and a remainder of 240.
The number 4 becomes the next digit in our result. 
Result so far: 65742.79285714
Subtracting 3360 from 3600 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The final outcome is 65742.79285714, with a leftover of 2.4e-07.
