We're dividing 3532370 by 840 
We want to divide 3532370 by 840.

Moving on to step 1:
If we divide 3 by 840, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 840

Going ahead to step 2:
840 can be fit into 35 0 times, resulting in a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Grab the next digit (3) from the dividend, add it to 35, then carry on: 353 / 840

On to step 3:
353 divided by 840 is 0 with a remainder of 353.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 353, we end up with 353.
Bring next digit (2) of the dividend behind the 353 and repeat the process: 3532 / 840

On to step 4:
The number 840 fits into 3532 4 times, leaving a remainder of 172.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 3360 from 3532 leaves us with 172.
Include the next digit (3) from the dividend after 172, then repeat: 1723 / 840

Advancing to step 5:
1723 divided by 840 is 2 with a remainder of 43.
Use 2 as the next digit of our solution. 
Result so far: 42.0
Deduct 1680 from 1723 and we're left with 43.
Include the next digit (7) from the dividend after 43, then repeat: 437 / 840

Moving on to step 6:
The number 840 fits into 437 0 times, leaving a remainder of 437.
Write down 0 as next digit of the result. 
Result so far: 420.0
Subtract 0 from 437 to get 437.
Take the next digit (0) from the dividend and append it to 437, then repeat: 4370 / 840

Step 7:
840 goes into 4370 5 times with a remainder of 170.
Write down 5 as next digit of the result. 
Result so far: 4205.0
If we subtract 4200 from 4370, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 8:
If we divide 1700 by 840, we get 2 and a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 4205.2
Subtracting 1680 from 1700 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
840 goes into 200 0 times with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 4205.2
If we subtract 0 from 200, we 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 10:
840 can be fit into 2000 2 times, resulting in a remainder of 320.
Record the quotient 2 as the next digit in the result. 
Result so far: 4205.202
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.

Step 11:
The number 840 fits into 3200 3 times, leaving a remainder of 680.
The number 3 becomes the next digit in our result. 
Result so far: 4205.2023
Deduct 2520 from 3200 and we're left 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.

Moving on to step 12:
840 goes into 6800 8 times with a remainder of 80.
The next digit of our result is 8. 
Result so far: 4205.20238
Subtract 6720 from 6800 to 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.

Going ahead to step 13:
The number 840 fits into 800 0 times, leaving a remainder of 800.
Put 0 as the next digit of the answer. 
Result so far: 4205.20238
Subtracting 0 from 800 leaves us with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Going ahead to step 14:
840 goes into 8000 9 times with a remainder of 440.
The number 9 becomes the next digit in our result. 
Result so far: 4205.2023809
If we take 7560 away from 8000, 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.

Advancing to step 15:
840 goes into 4400 5 times with a remainder of 200.
Record the quotient 5 as the next digit in the result. 
Result so far: 4205.20238095
Subtracting 4200 from 4400 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

After the division, we end up with 4205.20238095 and a remainder of 2e-07.
