Let's divide 210960 by 70
We want to figure out the number of times 210960 can be divided by 70.

Step 1:
2 divided by 70 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 70

Advancing to step 2:
When dividing 21 by 70, we get 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Take the next digit (0) from the dividend and append it to 21, then repeat: 210 / 70

Advancing to step 3:
If we divide 210 by 70, we get 3 and a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 210 away from 210, we end up with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 70

Advancing to step 4:
When dividing 9 by 70, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 30.0
If we subtract 0 from 9, we get 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 70

Advancing to step 5:
70 goes into 96 1 times with a remainder of 26.
The next digit of our result is 1. 
Result so far: 301.0
The remainder is 26 after subtracting 70 from 96.
Bring next digit (0) of the dividend behind the 26 and repeat the process: 260 / 70

Going ahead to step 6:
260 divided by 70 is 3 with a remainder of 50.
Put 3 as the next digit of the answer. 
Result so far: 3013.0
If we subtract 210 from 260, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 7:
If we divide 500 by 70, we get 7 and a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 3013.7
The remainder is 10 after subtracting 490 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
When dividing 100 by 70, we get 1 with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 3013.71
If we subtract 70 from 100, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
The number 70 fits into 300 4 times, leaving a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 3013.714
Deduct 280 from 300 and we're left 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.

Moving on to step 10:
200 divided by 70 is 2 with a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 3013.7142
If we take 140 away from 200, we end up with 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 11:
70 can be fit into 600 8 times, resulting in a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 3013.71428
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.

Going ahead to step 12:
70 goes into 400 5 times with a remainder of 50.
The next digit of our result is 5. 
Result so far: 3013.714285
If we subtract 350 from 400, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 13:
If we divide 500 by 70, we get 7 and a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 3013.7142857
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.

Moving on to step 14:
If we divide 100 by 70, we get 1 and a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 3013.71428571
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.

The final outcome is 3013.71428571, with a leftover of 3e-08.
