We're dividing 88721290 by 212 
The aim is to understand the frequency of 212 in 88721290.

Going ahead to step 1:
212 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 212

Step 2:
If we divide 88 by 212, we get 0 and a remainder of 88.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 88 after subtracting 0 from 88.
Append the next digit (7) from the dividend to 88 and continue with: 887 / 212

Step 3:
212 goes into 887 4 times with a remainder of 39.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 39 after subtracting 848 from 887.
Take the next digit (2) from the dividend and append it to 39, then repeat: 392 / 212

Going ahead to step 4:
If we divide 392 by 212, we get 1 and a remainder of 180.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
Subtract 212 from 392 to get 180.
Include the next digit (1) from the dividend after 180, then repeat: 1801 / 212

Advancing to step 5:
212 can be fit into 1801 8 times, resulting in a remainder of 105.
Use 8 as the next digit of our solution. 
Result so far: 418.0
If we subtract 1696 from 1801, we get 105.
Take the next digit (2) from the dividend and append it to 105, then repeat: 1052 / 212

Moving on to step 6:
212 can be fit into 1052 4 times, resulting in a remainder of 204.
Write down 4 as next digit of the result. 
Result so far: 4184.0
Deduct 848 from 1052 and we're left with 204.
Fetch the next digit (9) from the dividend, attach it to 204 and continue: 2049 / 212

Let's proceed to step 7:
212 can be fit into 2049 9 times, resulting in a remainder of 141.
Put 9 as the next digit of the answer. 
Result so far: 41849.0
Deduct 1908 from 2049 and we're left with 141.
Bring next digit (0) of the dividend behind the 141 and repeat the process: 1410 / 212

Moving on to step 8:
If we divide 1410 by 212, we get 6 and a remainder of 138.
Put 6 as the next digit of the answer. 
Result so far: 418496.0
If we subtract 1272 from 1410, we get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Going ahead to step 9:
The number 212 fits into 1380 6 times, leaving a remainder of 108.
The number 6 becomes the next digit in our result. 
Result so far: 418496.6
If we subtract 1272 from 1380, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 10:
If we divide 1080 by 212, we get 5 and a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 418496.65
Subtract 1060 from 1080 to 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:
If we divide 200 by 212, we get 0 and a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 418496.65
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 12:
If we divide 2000 by 212, we get 9 and a remainder of 92.
Write down 9 as next digit of the result. 
Result so far: 418496.6509
Subtract 1908 from 2000 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 13:
If we divide 920 by 212, we get 4 and a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 418496.65094
The remainder is 72 after subtracting 848 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 14:
If we divide 720 by 212, we get 3 and a remainder of 84.
Record the quotient 3 as the next digit in the result. 
Result so far: 418496.650943
If we subtract 636 from 720, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 15:
When dividing 840 by 212, we get 3 with a remainder of 204.
Put 3 as the next digit of the answer. 
Result so far: 418496.6509433
Subtract 636 from 840 to get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Our division results in 418496.6509433 with a remaining 2.04e-06.
