We look at the division of 69971507 by 138 
The aim is to understand the frequency of 138 in 69971507.

Going ahead to step 1:
138 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 138

On to step 2:
138 goes into 69 0 times with a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 69, we get 69.
Include the next digit (9) from the dividend after 69, then repeat: 699 / 138

Advancing to step 3:
If we divide 699 by 138, we get 5 and a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 690 from 699 to get 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 138

On to step 4:
138 can be fit into 97 0 times, resulting in a remainder of 97.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
If we take 0 away from 97, we end up with 97.
Append the next digit (1) from the dividend to 97 and continue with: 971 / 138

Going ahead to step 5:
The number 138 fits into 971 7 times, leaving a remainder of 5.
The next digit of our result is 7. 
Result so far: 507.0
Deduct 966 from 971 and we're left with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 138

Step 6:
When dividing 55 by 138, we get 0 with a remainder of 55.
The next digit of our result is 0. 
Result so far: 5070.0
The remainder is 55 after subtracting 0 from 55.
Append the next digit (0) from the dividend to 55 and continue with: 550 / 138

Step 7:
When dividing 550 by 138, we get 3 with a remainder of 136.
The next digit of our result is 3. 
Result so far: 50703.0
Subtract 414 from 550 to get 136.
Bring next digit (7) of the dividend behind the 136 and repeat the process: 1367 / 138

Moving on to step 8:
138 goes into 1367 9 times with a remainder of 125.
The next digit of our result is 9. 
Result so far: 507039.0
Deduct 1242 from 1367 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 9:
The number 138 fits into 1250 9 times, leaving a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 507039.9
Subtracting 1242 from 1250 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 10:
138 goes into 80 0 times with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 507039.9
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 11:
800 divided by 138 is 5 with a remainder of 110.
Write down 5 as next digit of the result. 
Result so far: 507039.905
The remainder is 110 after subtracting 690 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 12:
When dividing 1100 by 138, we get 7 with a remainder of 134.
Write down 7 as next digit of the result. 
Result so far: 507039.9057
Subtract 966 from 1100 to get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

On to step 13:
The number 138 fits into 1340 9 times, leaving a remainder of 98.
Record the quotient 9 as the next digit in the result. 
Result so far: 507039.90579
Subtracting 1242 from 1340 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 14:
When dividing 980 by 138, we get 7 with a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 507039.905797
If we take 966 away from 980, we end up 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.

Advancing to step 15:
138 can be fit into 140 1 times, resulting in a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 507039.9057971
If we subtract 138 from 140, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 16:
138 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 507039.9057971
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 507039.9057971 with a remaining 2e-08.
