We look at the division of 95060657 by 21 
The aim is to understand the frequency of 21 in 95060657.

On to step 1:
21 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 21

On to step 2:
When dividing 95 by 21, we get 4 with a remainder of 11.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 84 from 95 to get 11.
Bring next digit (0) of the dividend behind the 11 and repeat the process: 110 / 21

Moving on to step 3:
21 can be fit into 110 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
Subtracting 105 from 110 leaves us with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 21

Going ahead to step 4:
56 divided by 21 is 2 with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 452.0
If we subtract 42 from 56, we get 14.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 21

Let's proceed to step 5:
The number 21 fits into 140 6 times, leaving a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 4526.0
Deduct 126 from 140 and we're left with 14.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 21

Going ahead to step 6:
21 goes into 146 6 times with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 45266.0
Deduct 126 from 146 and we're left with 20.
Append the next digit (5) from the dividend to 20 and continue with: 205 / 21

Step 7:
The number 21 fits into 205 9 times, leaving a remainder of 16.
The next digit of our result is 9. 
Result so far: 452669.0
The remainder is 16 after subtracting 189 from 205.
Include the next digit (7) from the dividend after 16, then repeat: 167 / 21

Step 8:
167 divided by 21 is 7 with a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 4526697.0
The remainder is 20 after subtracting 147 from 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
21 can be fit into 200 9 times, resulting in a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 4526697.9
The remainder is 11 after subtracting 189 from 200.
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 10:
The number 21 fits into 110 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 4526697.95
Subtracting 105 from 110 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 11:
21 goes into 50 2 times with a remainder of 8.
The next digit of our result is 2. 
Result so far: 4526697.952
The remainder is 8 after subtracting 42 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
The number 21 fits into 80 3 times, leaving a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 4526697.9523
Subtract 63 from 80 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 13:
The number 21 fits into 170 8 times, leaving a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 4526697.95238
The remainder is 2 after subtracting 168 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 14:
The number 21 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 4526697.95238
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 15:
If we divide 200 by 21, we get 9 and a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 4526697.9523809
The remainder is 11 after subtracting 189 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 16:
The number 21 fits into 110 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 4526697.95238095
Subtracting 105 from 110 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 4526697.95238095, with a leftover of 5e-09.
