We look at the division of 20879604 by 231 
We want to divide 20879604 by 231.

Let's proceed to step 1:
If we divide 2 by 231, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 231

Advancing to step 2:
231 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Include the next digit (8) from the dividend after 20, then repeat: 208 / 231

Step 3:
231 goes into 208 0 times with a remainder of 208.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 208, we get 208.
Append the next digit (7) from the dividend to 208 and continue with: 2087 / 231

Step 4:
When dividing 2087 by 231, we get 9 with a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 2079 away from 2087, we end up with 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 231

Advancing to step 5:
When dividing 89 by 231, we get 0 with a remainder of 89.
Use 0 as the next digit of our solution. 
Result so far: 90.0
The remainder is 89 after subtracting 0 from 89.
Include the next digit (6) from the dividend after 89, then repeat: 896 / 231

Going ahead to step 6:
896 divided by 231 is 3 with a remainder of 203.
Put 3 as the next digit of the answer. 
Result so far: 903.0
Subtracting 693 from 896 leaves us with 203.
Append the next digit (0) from the dividend to 203 and continue with: 2030 / 231

Step 7:
The number 231 fits into 2030 8 times, leaving a remainder of 182.
Use 8 as the next digit of our solution. 
Result so far: 9038.0
The remainder is 182 after subtracting 1848 from 2030.
Include the next digit (4) from the dividend after 182, then repeat: 1824 / 231

On to step 8:
231 goes into 1824 7 times with a remainder of 207.
Record the quotient 7 as the next digit in the result. 
Result so far: 90387.0
If we subtract 1617 from 1824, we get 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

On to step 9:
If we divide 2070 by 231, we get 8 and a remainder of 222.
Use 8 as the next digit of our solution. 
Result so far: 90387.8
If we subtract 1848 from 2070, we get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Let's proceed to step 10:
231 goes into 2220 9 times with a remainder of 141.
Put 9 as the next digit of the answer. 
Result so far: 90387.89
If we subtract 2079 from 2220, we get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Moving on to step 11:
When dividing 1410 by 231, we get 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 90387.896
The remainder is 24 after subtracting 1386 from 1410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 12:
The number 231 fits into 240 1 times, leaving a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 90387.8961
If we take 231 away from 240, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 13:
The number 231 fits into 90 0 times, leaving a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 90387.8961
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 14:
When dividing 900 by 231, we get 3 with a remainder of 207.
Record the quotient 3 as the next digit in the result. 
Result so far: 90387.896103
If we take 693 away from 900, we end up with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Step 15:
2070 divided by 231 is 8 with a remainder of 222.
Put 8 as the next digit of the answer. 
Result so far: 90387.8961038
Deduct 1848 from 2070 and we're left with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

On to step 16:
231 goes into 2220 9 times with a remainder of 141.
Put 9 as the next digit of the answer. 
Result so far: 90387.89610389
Deduct 2079 from 2220 and we're left with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

The final result is 90387.89610389 with a remainder of 1.41e-07.
