Let's divide 216123 by 70
Our goal is to divide 216123 by 70.

Let's proceed to step 1:
If we divide 2 by 70, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 70

Advancing to step 2:
70 can be fit into 21 0 times, resulting in a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 70

Let's proceed to step 3:
If we divide 216 by 70, we get 3 and a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 210 away from 216, we end up with 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 70

Advancing to step 4:
61 divided by 70 is 0 with a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
If we take 0 away from 61, we end up with 61.
Include the next digit (2) from the dividend after 61, then repeat: 612 / 70

Moving on to step 5:
70 can be fit into 612 8 times, resulting in a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 308.0
If we subtract 560 from 612, we get 52.
Grab the next digit (3) from the dividend, add it to 52, then carry on: 523 / 70

Let's proceed to step 6:
523 divided by 70 is 7 with a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 3087.0
The remainder is 33 after subtracting 490 from 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 7:
The number 70 fits into 330 4 times, leaving a remainder of 50.
The next digit of our result is 4. 
Result so far: 3087.4
Deduct 280 from 330 and we're left 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.

Step 8:
70 goes into 500 7 times with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 3087.47
Subtract 490 from 500 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
70 goes into 100 1 times with a remainder of 30.
The next digit of our result is 1. 
Result so far: 3087.471
Subtracting 70 from 100 leaves us 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.

Let's proceed to step 10:
70 goes into 300 4 times with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 3087.4714
If we subtract 280 from 300, we 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.

Going ahead to step 11:
200 divided by 70 is 2 with a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 3087.47142
If we subtract 140 from 200, we 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.

Let's proceed to step 12:
The number 70 fits into 600 8 times, leaving a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 3087.471428
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 13:
400 divided by 70 is 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 3087.4714285
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.

Advancing to step 14:
When dividing 500 by 70, we get 7 with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 3087.47142857
If we take 490 away from 500, we end up 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.

The final outcome is 3087.47142857, with a leftover of 1e-08.
