21055929 ÷ 152 
The aim is to understand the frequency of 152 in 21055929.

Let's proceed to step 1:
152 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 take 0 away from 2, we end up with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 152

Moving on to step 2:
If we divide 21 by 152, we get 0 and a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Bring next digit (0) of the dividend behind the 21 and repeat the process: 210 / 152

Going ahead to step 3:
If we divide 210 by 152, we get 1 and a remainder of 58.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 152 from 210 to get 58.
Take the next digit (5) from the dividend and append it to 58, then repeat: 585 / 152

Let's proceed to step 4:
The number 152 fits into 585 3 times, leaving a remainder of 129.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 129 after subtracting 456 from 585.
Bring next digit (5) of the dividend behind the 129 and repeat the process: 1295 / 152

Moving on to step 5:
152 goes into 1295 8 times with a remainder of 79.
Record the quotient 8 as the next digit in the result. 
Result so far: 138.0
If we take 1216 away from 1295, we end up with 79.
Bring next digit (9) of the dividend behind the 79 and repeat the process: 799 / 152

Step 6:
The number 152 fits into 799 5 times, leaving a remainder of 39.
Record the quotient 5 as the next digit in the result. 
Result so far: 1385.0
Subtracting 760 from 799 leaves us with 39.
Grab the next digit (2) from the dividend, add it to 39, then carry on: 392 / 152

On to step 7:
The number 152 fits into 392 2 times, leaving a remainder of 88.
Put 2 as the next digit of the answer. 
Result so far: 13852.0
Subtracting 304 from 392 leaves us with 88.
Grab the next digit (9) from the dividend, add it to 88, then carry on: 889 / 152

Advancing to step 8:
The number 152 fits into 889 5 times, leaving a remainder of 129.
The next digit of our result is 5. 
Result so far: 138525.0
Subtracting 760 from 889 leaves us with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Moving on to step 9:
If we divide 1290 by 152, we get 8 and a remainder of 74.
Use 8 as the next digit of our solution. 
Result so far: 138525.8
Deduct 1216 from 1290 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 10:
152 goes into 740 4 times with a remainder of 132.
Use 4 as the next digit of our solution. 
Result so far: 138525.84
The remainder is 132 after subtracting 608 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Advancing to step 11:
152 goes into 1320 8 times with a remainder of 104.
Use 8 as the next digit of our solution. 
Result so far: 138525.848
Deduct 1216 from 1320 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 12:
If we divide 1040 by 152, we get 6 and a remainder of 128.
Record the quotient 6 as the next digit in the result. 
Result so far: 138525.8486
If we take 912 away from 1040, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 13:
The number 152 fits into 1280 8 times, leaving a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 138525.84868
Deduct 1216 from 1280 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 14:
When dividing 640 by 152, we get 4 with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 138525.848684
Subtracting 608 from 640 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 15:
320 divided by 152 is 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 138525.8486842
If we take 304 away from 320, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 16:
160 divided by 152 is 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 138525.84868421
Deduct 152 from 160 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.

The final outcome is 138525.84868421, with a leftover of 8e-09.
