71550769 divided by 138 
The aim is to understand the frequency of 138 in 71550769.

Step 1:
138 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 138

Going ahead to step 2:
If we divide 71 by 138, we get 0 and a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Take the next digit (5) from the dividend and append it to 71, then repeat: 715 / 138

Moving on to step 3:
The number 138 fits into 715 5 times, leaving a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 690 from 715 to get 25.
Include the next digit (5) from the dividend after 25, then repeat: 255 / 138

Advancing to step 4:
When dividing 255 by 138, we get 1 with a remainder of 117.
Use 1 as the next digit of our solution. 
Result so far: 51.0
If we take 138 away from 255, we end up with 117.
Grab the next digit (0) from the dividend, add it to 117, then carry on: 1170 / 138

Going ahead to step 5:
138 can be fit into 1170 8 times, resulting in a remainder of 66.
The next digit of our result is 8. 
Result so far: 518.0
Subtracting 1104 from 1170 leaves us with 66.
Append the next digit (7) from the dividend to 66 and continue with: 667 / 138

On to step 6:
667 divided by 138 is 4 with a remainder of 115.
The next digit of our result is 4. 
Result so far: 5184.0
If we take 552 away from 667, we end up with 115.
Take the next digit (6) from the dividend and append it to 115, then repeat: 1156 / 138

Let's proceed to step 7:
The number 138 fits into 1156 8 times, leaving a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 51848.0
Deduct 1104 from 1156 and we're left with 52.
Take the next digit (9) from the dividend and append it to 52, then repeat: 529 / 138

Moving on to step 8:
The number 138 fits into 529 3 times, leaving a remainder of 115.
Use 3 as the next digit of our solution. 
Result so far: 518483.0
Subtract 414 from 529 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Moving on to step 9:
1150 divided by 138 is 8 with a remainder of 46.
Put 8 as the next digit of the answer. 
Result so far: 518483.8
Subtract 1104 from 1150 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 10:
If we divide 460 by 138, we get 3 and a remainder of 46.
The next digit of our result is 3. 
Result so far: 518483.83
Subtracting 414 from 460 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 11:
138 goes into 460 3 times with a remainder of 46.
Write down 3 as next digit of the result. 
Result so far: 518483.833
Subtract 414 from 460 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Our division results in 518483.833 with a remaining 0.0046.
