We look at the division of 21701005 by 444 
The aim is to understand the frequency of 444 in 21701005.

On to step 1:
2 divided by 444 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 444

On to step 2:
444 can be fit into 21 0 times, resulting in a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Take the next digit (7) from the dividend and append it to 21, then repeat: 217 / 444

On to step 3:
444 can be fit into 217 0 times, resulting in a remainder of 217.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 217 and we're left with 217.
Fetch the next digit (0) from the dividend, attach it to 217 and continue: 2170 / 444

Step 4:
444 can be fit into 2170 4 times, resulting in a remainder of 394.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 1776 from 2170 to get 394.
Bring next digit (1) of the dividend behind the 394 and repeat the process: 3941 / 444

Moving on to step 5:
444 can be fit into 3941 8 times, resulting in a remainder of 389.
Put 8 as the next digit of the answer. 
Result so far: 48.0
The remainder is 389 after subtracting 3552 from 3941.
Include the next digit (0) from the dividend after 389, then repeat: 3890 / 444

Step 6:
The number 444 fits into 3890 8 times, leaving a remainder of 338.
Use 8 as the next digit of our solution. 
Result so far: 488.0
Deduct 3552 from 3890 and we're left with 338.
Take the next digit (0) from the dividend and append it to 338, then repeat: 3380 / 444

Going ahead to step 7:
The number 444 fits into 3380 7 times, leaving a remainder of 272.
Record the quotient 7 as the next digit in the result. 
Result so far: 4887.0
The remainder is 272 after subtracting 3108 from 3380.
Include the next digit (5) from the dividend after 272, then repeat: 2725 / 444

Advancing to step 8:
If we divide 2725 by 444, we get 6 and a remainder of 61.
Put 6 as the next digit of the answer. 
Result so far: 48876.0
The remainder is 61 after subtracting 2664 from 2725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 9:
The number 444 fits into 610 1 times, leaving a remainder of 166.
Record the quotient 1 as the next digit in the result. 
Result so far: 48876.1
If we subtract 444 from 610, we get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Going ahead to step 10:
If we divide 1660 by 444, we get 3 and a remainder of 328.
Write down 3 as next digit of the result. 
Result so far: 48876.13
The remainder is 328 after subtracting 1332 from 1660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Step 11:
If we divide 3280 by 444, we get 7 and a remainder of 172.
Use 7 as the next digit of our solution. 
Result so far: 48876.137
If we take 3108 away from 3280, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 12:
1720 divided by 444 is 3 with a remainder of 388.
Put 3 as the next digit of the answer. 
Result so far: 48876.1373
If we take 1332 away from 1720, we end up with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Advancing to step 13:
If we divide 3880 by 444, we get 8 and a remainder of 328.
The next digit of our result is 8. 
Result so far: 48876.13738
Subtract 3552 from 3880 to get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Step 14:
When dividing 3280 by 444, we get 7 with a remainder of 172.
The number 7 becomes the next digit in our result. 
Result so far: 48876.137387
Subtract 3108 from 3280 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

On to step 15:
444 goes into 1720 3 times with a remainder of 388.
Put 3 as the next digit of the answer. 
Result so far: 48876.1373873
Subtract 1332 from 1720 to get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Step 16:
3880 divided by 444 is 8 with a remainder of 328.
The next digit of our result is 8. 
Result so far: 48876.13738738
Subtract 3552 from 3880 to get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

In conclusion, the division gives 48876.13738738 with a balance of 3.28e-07.
