Let's divide 22905431 by 138
The aim is to understand the frequency of 138 in 22905431.

On to step 1:
If we divide 2 by 138, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 138

Moving on to step 2:
When dividing 22 by 138, we get 0 with a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 22, we end up with 22.
Bring next digit (9) of the dividend behind the 22 and repeat the process: 229 / 138

Let's proceed to step 3:
138 goes into 229 1 times with a remainder of 91.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 138 from 229, we get 91.
Bring next digit (0) of the dividend behind the 91 and repeat the process: 910 / 138

Step 4:
If we divide 910 by 138, we get 6 and a remainder of 82.
The next digit of our result is 6. 
Result so far: 16.0
The remainder is 82 after subtracting 828 from 910.
Take the next digit (5) from the dividend and append it to 82, then repeat: 825 / 138

Going ahead to step 5:
If we divide 825 by 138, we get 5 and a remainder of 135.
The number 5 becomes the next digit in our result. 
Result so far: 165.0
If we take 690 away from 825, we end up with 135.
Grab the next digit (4) from the dividend, add it to 135, then carry on: 1354 / 138

Let's proceed to step 6:
The number 138 fits into 1354 9 times, leaving a remainder of 112.
Put 9 as the next digit of the answer. 
Result so far: 1659.0
If we subtract 1242 from 1354, we get 112.
Fetch the next digit (3) from the dividend, attach it to 112 and continue: 1123 / 138

Step 7:
1123 divided by 138 is 8 with a remainder of 19.
Record the quotient 8 as the next digit in the result. 
Result so far: 16598.0
Subtracting 1104 from 1123 leaves us with 19.
Bring next digit (1) of the dividend behind the 19 and repeat the process: 191 / 138

Moving on to step 8:
If we divide 191 by 138, we get 1 and a remainder of 53.
The number 1 becomes the next digit in our result. 
Result so far: 165981.0
Deduct 138 from 191 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 9:
530 divided by 138 is 3 with a remainder of 116.
The number 3 becomes the next digit in our result. 
Result so far: 165981.3
The remainder is 116 after subtracting 414 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 10:
138 goes into 1160 8 times with a remainder of 56.
The next digit of our result is 8. 
Result so far: 165981.38
Subtracting 1104 from 1160 leaves us 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 11:
When dividing 560 by 138, we get 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 165981.384
Subtracting 552 from 560 leaves us 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.

Advancing to step 12:
When dividing 80 by 138, we get 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 165981.384
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 13:
138 can be fit into 800 5 times, resulting in a remainder of 110.
Put 5 as the next digit of the answer. 
Result so far: 165981.38405
Subtract 690 from 800 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 14:
The number 138 fits into 1100 7 times, leaving a remainder of 134.
Write down 7 as next digit of the result. 
Result so far: 165981.384057
If we take 966 away from 1100, we end up with 134.
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 15:
If we divide 1340 by 138, we get 9 and a remainder of 98.
Put 9 as the next digit of the answer. 
Result so far: 165981.3840579
The remainder is 98 after subtracting 1242 from 1340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Advancing to step 16:
When dividing 980 by 138, we get 7 with a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 165981.38405797
Subtracting 966 from 980 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 165981.38405797, with a leftover of 1.4e-08.
