We look at the division of 20561 by 70 
We want to figure out the number of times 20561 can be divided by 70.

On to step 1:
70 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 70

Step 2:
70 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Append the next digit (5) from the dividend to 20 and continue with: 205 / 70

On to step 3:
70 can be fit into 205 2 times, resulting in a remainder of 65.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 140 away from 205, we end up with 65.
Fetch the next digit (6) from the dividend, attach it to 65 and continue: 656 / 70

Let's proceed to step 4:
70 can be fit into 656 9 times, resulting in a remainder of 26.
The next digit of our result is 9. 
Result so far: 29.0
Subtract 630 from 656 to get 26.
Fetch the next digit (1) from the dividend, attach it to 26 and continue: 261 / 70

Moving on to step 5:
When dividing 261 by 70, we get 3 with a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 293.0
If we subtract 210 from 261, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 6:
70 can be fit into 510 7 times, resulting in a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 293.7
If we subtract 490 from 510, 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.

Let's proceed to step 7:
200 divided by 70 is 2 with a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 293.72
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.

Advancing to step 8:
70 goes into 600 8 times with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 293.728
Subtracting 560 from 600 leaves us 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.

Let's proceed to step 9:
400 divided by 70 is 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 293.7285
If we take 350 away from 400, we end up 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 10:
The number 70 fits into 500 7 times, leaving a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 293.72857
Subtracting 490 from 500 leaves us 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.

On to step 11:
If we divide 100 by 70, we get 1 and a remainder of 30.
The next digit of our result is 1. 
Result so far: 293.728571
Subtract 70 from 100 to 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.

Going ahead to step 12:
When dividing 300 by 70, we get 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 293.7285714
If we take 280 away from 300, we end up 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.

On to step 13:
200 divided by 70 is 2 with a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 293.72857142
Deduct 140 from 200 and we're left 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.

In conclusion, the division gives 293.72857142 with a balance of 6e-08.
