We're dividing 20988101 by 215 
We want to divide 20988101 by 215.

On to step 1:
When dividing 2 by 215, we get 0 with 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.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 215

Moving on to step 2:
The number 215 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 215

Let's proceed to step 3:
The number 215 fits into 209 0 times, leaving a remainder of 209.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 209, we get 209.
Append the next digit (8) from the dividend to 209 and continue with: 2098 / 215

Advancing to step 4:
2098 divided by 215 is 9 with a remainder of 163.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 1935 from 2098 to get 163.
Take the next digit (8) from the dividend and append it to 163, then repeat: 1638 / 215

Let's proceed to step 5:
The number 215 fits into 1638 7 times, leaving a remainder of 133.
Put 7 as the next digit of the answer. 
Result so far: 97.0
Subtract 1505 from 1638 to get 133.
Take the next digit (1) from the dividend and append it to 133, then repeat: 1331 / 215

On to step 6:
1331 divided by 215 is 6 with a remainder of 41.
Record the quotient 6 as the next digit in the result. 
Result so far: 976.0
The remainder is 41 after subtracting 1290 from 1331.
Append the next digit (0) from the dividend to 41 and continue with: 410 / 215

Let's proceed to step 7:
When dividing 410 by 215, we get 1 with a remainder of 195.
The next digit of our result is 1. 
Result so far: 9761.0
If we subtract 215 from 410, we get 195.
Include the next digit (1) from the dividend after 195, then repeat: 1951 / 215

Moving on to step 8:
215 can be fit into 1951 9 times, resulting in a remainder of 16.
Record the quotient 9 as the next digit in the result. 
Result so far: 97619.0
If we take 1935 away from 1951, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
160 divided by 215 is 0 with a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 97619.0
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 10:
If we divide 1600 by 215, we get 7 and a remainder of 95.
Record the quotient 7 as the next digit in the result. 
Result so far: 97619.07
The remainder is 95 after subtracting 1505 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Let's proceed to step 11:
215 goes into 950 4 times with a remainder of 90.
The number 4 becomes the next digit in our result. 
Result so far: 97619.074
Subtracting 860 from 950 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.

Advancing to step 12:
215 goes into 900 4 times with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 97619.0744
If we take 860 away from 900, we end up 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.

In conclusion, the division gives 97619.0744 with a balance of 0.0004.
