Let's divide 321240 by 70
We want to divide 321240 by 70.

On to step 1:
70 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 70

Advancing to step 2:
The number 70 fits into 32 0 times, leaving a remainder of 32.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 32 leaves us with 32.
Append the next digit (1) from the dividend to 32 and continue with: 321 / 70

Step 3:
The number 70 fits into 321 4 times, leaving a remainder of 41.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 280 from 321 leaves us with 41.
Append the next digit (2) from the dividend to 41 and continue with: 412 / 70

Moving on to step 4:
412 divided by 70 is 5 with a remainder of 62.
The next digit of our result is 5. 
Result so far: 45.0
If we take 350 away from 412, we end up with 62.
Fetch the next digit (4) from the dividend, attach it to 62 and continue: 624 / 70

Going ahead to step 5:
The number 70 fits into 624 8 times, leaving a remainder of 64.
The next digit of our result is 8. 
Result so far: 458.0
Subtracting 560 from 624 leaves us with 64.
Append the next digit (0) from the dividend to 64 and continue with: 640 / 70

Advancing to step 6:
The number 70 fits into 640 9 times, leaving a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 4589.0
The remainder is 10 after subtracting 630 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
The number 70 fits into 100 1 times, leaving a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 4589.1
The remainder is 30 after subtracting 70 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
70 goes into 300 4 times with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 4589.14
The remainder is 20 after subtracting 280 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
If we divide 200 by 70, we get 2 and a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 4589.142
Subtract 140 from 200 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 10:
The number 70 fits into 600 8 times, leaving a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 4589.1428
Deduct 560 from 600 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
70 can be fit into 400 5 times, resulting in a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 4589.14285
Subtracting 350 from 400 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 12:
When dividing 500 by 70, we get 7 with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 4589.142857
Deduct 490 from 500 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
100 divided by 70 is 1 with a remainder of 30.
The next digit of our result is 1. 
Result so far: 4589.1428571
Deduct 70 from 100 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 14:
300 divided by 70 is 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 4589.14285714
Subtract 280 from 300 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 4589.14285714, and the remainder is 2e-08.
