We look at the division of 26215620 by 214 
The aim is to understand the frequency of 214 in 26215620.

Advancing to step 1:
When dividing 2 by 214, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 214

Advancing to step 2:
The number 214 fits into 26 0 times, leaving a remainder of 26.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 26, we get 26.
Fetch the next digit (2) from the dividend, attach it to 26 and continue: 262 / 214

On to step 3:
When dividing 262 by 214, we get 1 with a remainder of 48.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 214 away from 262, we end up with 48.
Take the next digit (1) from the dividend and append it to 48, then repeat: 481 / 214

Let's proceed to step 4:
214 can be fit into 481 2 times, resulting in a remainder of 53.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 428 from 481 to get 53.
Take the next digit (5) from the dividend and append it to 53, then repeat: 535 / 214

Advancing to step 5:
214 can be fit into 535 2 times, resulting in a remainder of 107.
Write down 2 as next digit of the result. 
Result so far: 122.0
The remainder is 107 after subtracting 428 from 535.
Take the next digit (6) from the dividend and append it to 107, then repeat: 1076 / 214

Moving on to step 6:
214 can be fit into 1076 5 times, resulting in a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 1225.0
Subtract 1070 from 1076 to get 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 214

Moving on to step 7:
214 goes into 62 0 times with a remainder of 62.
The next digit of our result is 0. 
Result so far: 12250.0
Deduct 0 from 62 and we're left with 62.
Bring next digit (0) of the dividend behind the 62 and repeat the process: 620 / 214

On to step 8:
214 goes into 620 2 times with a remainder of 192.
The next digit of our result is 2. 
Result so far: 122502.0
Deduct 428 from 620 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 9:
1920 divided by 214 is 8 with a remainder of 208.
The number 8 becomes the next digit in our result. 
Result so far: 122502.8
Deduct 1712 from 1920 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Let's proceed to step 10:
The number 214 fits into 2080 9 times, leaving a remainder of 154.
Put 9 as the next digit of the answer. 
Result so far: 122502.89
Deduct 1926 from 2080 and we're left with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Advancing to step 11:
The number 214 fits into 1540 7 times, leaving a remainder of 42.
Use 7 as the next digit of our solution. 
Result so far: 122502.897
Subtracting 1498 from 1540 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 12:
214 can be fit into 420 1 times, resulting in a remainder of 206.
The number 1 becomes the next digit in our result. 
Result so far: 122502.8971
Subtracting 214 from 420 leaves us with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

On to step 13:
The number 214 fits into 2060 9 times, leaving a remainder of 134.
Record the quotient 9 as the next digit in the result. 
Result so far: 122502.89719
The remainder is 134 after subtracting 1926 from 2060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Let's proceed to step 14:
The number 214 fits into 1340 6 times, leaving a remainder of 56.
The next digit of our result is 6. 
Result so far: 122502.897196
Deduct 1284 from 1340 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 15:
If we divide 560 by 214, we get 2 and a remainder of 132.
Write down 2 as next digit of the result. 
Result so far: 122502.8971962
If we subtract 428 from 560, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

On to step 16:
214 can be fit into 1320 6 times, resulting in a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 122502.89719626
If we take 1284 away from 1320, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

In conclusion, the division gives 122502.89719626 with a balance of 3.6e-08.
