We're dividing 21721149 by 34 
The aim is to understand the frequency of 34 in 21721149.

On to step 1:
If we divide 2 by 34, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 34

Let's proceed to step 2:
34 goes into 21 0 times with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Include the next digit (7) from the dividend after 21, then repeat: 217 / 34

Advancing to step 3:
When dividing 217 by 34, we get 6 with a remainder of 13.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 13 after subtracting 204 from 217.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 34

Step 4:
132 divided by 34 is 3 with a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
Subtracting 102 from 132 leaves us with 30.
Grab the next digit (1) from the dividend, add it to 30, then carry on: 301 / 34

Going ahead to step 5:
34 goes into 301 8 times with a remainder of 29.
Record the quotient 8 as the next digit in the result. 
Result so far: 638.0
If we subtract 272 from 301, we get 29.
Fetch the next digit (1) from the dividend, attach it to 29 and continue: 291 / 34

On to step 6:
The number 34 fits into 291 8 times, leaving a remainder of 19.
The next digit of our result is 8. 
Result so far: 6388.0
The remainder is 19 after subtracting 272 from 291.
Fetch the next digit (4) from the dividend, attach it to 19 and continue: 194 / 34

Moving on to step 7:
When dividing 194 by 34, we get 5 with a remainder of 24.
The next digit of our result is 5. 
Result so far: 63885.0
If we subtract 170 from 194, we get 24.
Include the next digit (9) from the dividend after 24, then repeat: 249 / 34

Advancing to step 8:
34 can be fit into 249 7 times, resulting in a remainder of 11.
The next digit of our result is 7. 
Result so far: 638857.0
Deduct 238 from 249 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 9:
110 divided by 34 is 3 with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 638857.3
Deduct 102 from 110 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
34 goes into 80 2 times with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 638857.32
Subtracting 68 from 80 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 11:
34 can be fit into 120 3 times, resulting in a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 638857.323
If we take 102 away from 120, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 12:
180 divided by 34 is 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 638857.3235
If we take 170 away from 180, we end up 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.

Going ahead to step 13:
34 goes into 100 2 times with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 638857.32352
If we subtract 68 from 100, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 14:
When dividing 320 by 34, we get 9 with a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 638857.323529
Subtracting 306 from 320 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 15:
34 can be fit into 140 4 times, resulting in a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 638857.3235294
Subtract 136 from 140 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 16:
40 divided by 34 is 1 with a remainder of 6.
The next digit of our result is 1. 
Result so far: 638857.32352941
Deduct 34 from 40 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

After the division, we end up with 638857.32352941 and a remainder of 6e-09.
