21005682 divided by 214 
The aim is to understand the frequency of 214 in 21005682.

Advancing to step 1:
214 can be fit into 2 0 times, resulting in 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.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 214

Let's proceed to step 2:
When dividing 21 by 214, we get 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Grab the next digit (0) from the dividend, add it to 21, then carry on: 210 / 214

On to step 3:
214 can be fit into 210 0 times, resulting in a remainder of 210.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 210 after subtracting 0 from 210.
Include the next digit (0) from the dividend after 210, then repeat: 2100 / 214

Let's proceed to step 4:
When dividing 2100 by 214, we get 9 with a remainder of 174.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 1926 from 2100 and we're left with 174.
Take the next digit (5) from the dividend and append it to 174, then repeat: 1745 / 214

Let's proceed to step 5:
If we divide 1745 by 214, we get 8 and a remainder of 33.
The next digit of our result is 8. 
Result so far: 98.0
Subtracting 1712 from 1745 leaves us with 33.
Take the next digit (6) from the dividend and append it to 33, then repeat: 336 / 214

On to step 6:
When dividing 336 by 214, we get 1 with a remainder of 122.
The next digit of our result is 1. 
Result so far: 981.0
Deduct 214 from 336 and we're left with 122.
Take the next digit (8) from the dividend and append it to 122, then repeat: 1228 / 214

Moving on to step 7:
214 goes into 1228 5 times with a remainder of 158.
Use 5 as the next digit of our solution. 
Result so far: 9815.0
The remainder is 158 after subtracting 1070 from 1228.
Fetch the next digit (2) from the dividend, attach it to 158 and continue: 1582 / 214

On to step 8:
214 goes into 1582 7 times with a remainder of 84.
The number 7 becomes the next digit in our result. 
Result so far: 98157.0
Deduct 1498 from 1582 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 9:
214 goes into 840 3 times with a remainder of 198.
Record the quotient 3 as the next digit in the result. 
Result so far: 98157.3
If we take 642 away from 840, we end up with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Advancing to step 10:
If we divide 1980 by 214, we get 9 and a remainder of 54.
Use 9 as the next digit of our solution. 
Result so far: 98157.39
Deduct 1926 from 1980 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 11:
214 can be fit into 540 2 times, resulting in a remainder of 112.
Put 2 as the next digit of the answer. 
Result so far: 98157.392
If we take 428 away from 540, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 12:
214 goes into 1120 5 times with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 98157.3925
Deduct 1070 from 1120 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 13:
214 goes into 500 2 times with a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 98157.39252
If we subtract 428 from 500, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 14:
If we divide 720 by 214, we get 3 and a remainder of 78.
The next digit of our result is 3. 
Result so far: 98157.392523
Deduct 642 from 720 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 15:
The number 214 fits into 780 3 times, leaving a remainder of 138.
Put 3 as the next digit of the answer. 
Result so far: 98157.3925233
Deduct 642 from 780 and we're left with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

The final outcome is 98157.3925233, with a leftover of 1.38e-06.
