Let's divide 53494034 by 840
Our goal is to divide 53494034 by 840.

Advancing to step 1:
The number 840 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 840

Going ahead to step 2:
The number 840 fits into 53 0 times, leaving a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Fetch the next digit (4) from the dividend, attach it to 53 and continue: 534 / 840

Moving on to step 3:
The number 840 fits into 534 0 times, leaving a remainder of 534.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 534, we end up with 534.
Fetch the next digit (9) from the dividend, attach it to 534 and continue: 5349 / 840

Going ahead to step 4:
840 goes into 5349 6 times with a remainder of 309.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 5040 away from 5349, we end up with 309.
Take the next digit (4) from the dividend and append it to 309, then repeat: 3094 / 840

On to step 5:
3094 divided by 840 is 3 with a remainder of 574.
Write down 3 as next digit of the result. 
Result so far: 63.0
If we subtract 2520 from 3094, we get 574.
Grab the next digit (0) from the dividend, add it to 574, then carry on: 5740 / 840

Advancing to step 6:
If we divide 5740 by 840, we get 6 and a remainder of 700.
Write down 6 as next digit of the result. 
Result so far: 636.0
If we subtract 5040 from 5740, we get 700.
Grab the next digit (3) from the dividend, add it to 700, then carry on: 7003 / 840

On to step 7:
840 can be fit into 7003 8 times, resulting in a remainder of 283.
Record the quotient 8 as the next digit in the result. 
Result so far: 6368.0
Subtracting 6720 from 7003 leaves us with 283.
Grab the next digit (4) from the dividend, add it to 283, then carry on: 2834 / 840

Moving on to step 8:
The number 840 fits into 2834 3 times, leaving a remainder of 314.
Write down 3 as next digit of the result. 
Result so far: 63683.0
Subtract 2520 from 2834 to get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Going ahead to step 9:
The number 840 fits into 3140 3 times, leaving a remainder of 620.
Put 3 as the next digit of the answer. 
Result so far: 63683.3
If we subtract 2520 from 3140, we get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Step 10:
6200 divided by 840 is 7 with a remainder of 320.
The next digit of our result is 7. 
Result so far: 63683.37
Deduct 5880 from 6200 and we're left 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.

Let's proceed to step 11:
840 goes into 3200 3 times with a remainder of 680.
Put 3 as the next digit of the answer. 
Result so far: 63683.373
Subtracting 2520 from 3200 leaves us with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Let's proceed to step 12:
840 can be fit into 6800 8 times, resulting in a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 63683.3738
Deduct 6720 from 6800 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 13:
800 divided by 840 is 0 with a remainder of 800.
Write down 0 as next digit of the result. 
Result so far: 63683.3738
The remainder is 800 after subtracting 0 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

On to step 14:
The number 840 fits into 8000 9 times, leaving a remainder of 440.
Record the quotient 9 as the next digit in the result. 
Result so far: 63683.373809
If we subtract 7560 from 8000, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 15:
840 can be fit into 4400 5 times, resulting in a remainder of 200.
The next digit of our result is 5. 
Result so far: 63683.3738095
The remainder is 200 after subtracting 4200 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 16:
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: 63683.37380952
Subtract 1680 from 2000 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The quotient of the division is 63683.37380952, and the remainder is 3.2e-07.
