33921035 ÷ 840 
Our goal is to divide 33921035 by 840.

On to step 1:
When dividing 3 by 840, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 840

On to step 2:
840 can be fit into 33 0 times, resulting in a remainder of 33.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 33 and we're left with 33.
Bring next digit (9) of the dividend behind the 33 and repeat the process: 339 / 840

Going ahead to step 3:
When dividing 339 by 840, we get 0 with a remainder of 339.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 339 after subtracting 0 from 339.
Include the next digit (2) from the dividend after 339, then repeat: 3392 / 840

Advancing to step 4:
840 goes into 3392 4 times with a remainder of 32.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 3360 from 3392 and we're left with 32.
Append the next digit (1) from the dividend to 32 and continue with: 321 / 840

Going ahead to step 5:
321 divided by 840 is 0 with a remainder of 321.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Subtracting 0 from 321 leaves us with 321.
Grab the next digit (0) from the dividend, add it to 321, then carry on: 3210 / 840

On to step 6:
3210 divided by 840 is 3 with a remainder of 690.
Put 3 as the next digit of the answer. 
Result so far: 403.0
If we subtract 2520 from 3210, we get 690.
Fetch the next digit (3) from the dividend, attach it to 690 and continue: 6903 / 840

Advancing to step 7:
840 can be fit into 6903 8 times, resulting in a remainder of 183.
The next digit of our result is 8. 
Result so far: 4038.0
Deduct 6720 from 6903 and we're left with 183.
Take the next digit (5) from the dividend and append it to 183, then repeat: 1835 / 840

On to step 8:
840 goes into 1835 2 times with a remainder of 155.
The number 2 becomes the next digit in our result. 
Result so far: 40382.0
If we take 1680 away from 1835, we end up with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

On to step 9:
When dividing 1550 by 840, we get 1 with a remainder of 710.
The next digit of our result is 1. 
Result so far: 40382.1
The remainder is 710 after subtracting 840 from 1550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Going ahead to step 10:
840 goes into 7100 8 times with a remainder of 380.
Use 8 as the next digit of our solution. 
Result so far: 40382.18
If we take 6720 away from 7100, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Going ahead to step 11:
840 can be fit into 3800 4 times, resulting in a remainder of 440.
Record the quotient 4 as the next digit in the result. 
Result so far: 40382.184
If we take 3360 away from 3800, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 12:
840 can be fit into 4400 5 times, resulting in a remainder of 200.
The number 5 becomes the next digit in our result. 
Result so far: 40382.1845
Subtract 4200 from 4400 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 13:
If we divide 2000 by 840, we get 2 and a remainder of 320.
Record the quotient 2 as the next digit in the result. 
Result so far: 40382.18452
Subtracting 1680 from 2000 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 14:
3200 divided by 840 is 3 with a remainder of 680.
Use 3 as the next digit of our solution. 
Result so far: 40382.184523
Subtract 2520 from 3200 to get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Moving on to step 15:
If we divide 6800 by 840, we get 8 and a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 40382.1845238
If we subtract 6720 from 6800, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 16:
840 goes into 800 0 times with a remainder of 800.
Use 0 as the next digit of our solution. 
Result so far: 40382.1845238
If we subtract 0 from 800, we get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

The final outcome is 40382.1845238, with a leftover of 8e-07.
