Let's divide 21097640 by 212
Let's see how many times 212 fits into 21097640.

Moving on to step 1:
2 divided by 212 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 212

On to step 2:
If we divide 21 by 212, we get 0 and a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Take the next digit (0) from the dividend and append it to 21, then repeat: 210 / 212

Let's proceed to step 3:
212 goes into 210 0 times with a remainder of 210.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 210, we get 210.
Append the next digit (9) from the dividend to 210 and continue with: 2109 / 212

Moving on to step 4:
When dividing 2109 by 212, we get 9 with a remainder of 201.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 1908 from 2109 to get 201.
Append the next digit (7) from the dividend to 201 and continue with: 2017 / 212

On to step 5:
If we divide 2017 by 212, we get 9 and a remainder of 109.
Use 9 as the next digit of our solution. 
Result so far: 99.0
Subtracting 1908 from 2017 leaves us with 109.
Fetch the next digit (6) from the dividend, attach it to 109 and continue: 1096 / 212

Step 6:
If we divide 1096 by 212, we get 5 and a remainder of 36.
The next digit of our result is 5. 
Result so far: 995.0
If we take 1060 away from 1096, we end up with 36.
Include the next digit (4) from the dividend after 36, then repeat: 364 / 212

Let's proceed to step 7:
When dividing 364 by 212, we get 1 with a remainder of 152.
The number 1 becomes the next digit in our result. 
Result so far: 9951.0
Deduct 212 from 364 and we're left with 152.
Fetch the next digit (0) from the dividend, attach it to 152 and continue: 1520 / 212

Advancing to step 8:
212 goes into 1520 7 times with a remainder of 36.
The next digit of our result is 7. 
Result so far: 99517.0
Subtract 1484 from 1520 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 9:
212 goes into 360 1 times with a remainder of 148.
The next digit of our result is 1. 
Result so far: 99517.1
The remainder is 148 after subtracting 212 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 10:
212 can be fit into 1480 6 times, resulting in a remainder of 208.
Write down 6 as next digit of the result. 
Result so far: 99517.16
Subtract 1272 from 1480 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 11:
212 can be fit into 2080 9 times, resulting in a remainder of 172.
The number 9 becomes the next digit in our result. 
Result so far: 99517.169
The remainder is 172 after subtracting 1908 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Going ahead to step 12:
If we divide 1720 by 212, we get 8 and a remainder of 24.
The next digit of our result is 8. 
Result so far: 99517.1698
Subtract 1696 from 1720 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 13:
The number 212 fits into 240 1 times, leaving a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 99517.16981
Subtract 212 from 240 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 14:
If we divide 280 by 212, we get 1 and a remainder of 68.
The next digit of our result is 1. 
Result so far: 99517.169811
Subtracting 212 from 280 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Our division results in 99517.169811 with a remaining 6.8e-06.
