76242848 ÷ 138 
The aim is to understand the frequency of 138 in 76242848.

Advancing to step 1:
If we divide 7 by 138, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 138

Going ahead to step 2:
The number 138 fits into 76 0 times, leaving a remainder of 76.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 76 after subtracting 0 from 76.
Take the next digit (2) from the dividend and append it to 76, then repeat: 762 / 138

Step 3:
When dividing 762 by 138, we get 5 with a remainder of 72.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 690 away from 762, we end up with 72.
Fetch the next digit (4) from the dividend, attach it to 72 and continue: 724 / 138

Let's proceed to step 4:
If we divide 724 by 138, we get 5 and a remainder of 34.
Write down 5 as next digit of the result. 
Result so far: 55.0
If we take 690 away from 724, we end up with 34.
Grab the next digit (2) from the dividend, add it to 34, then carry on: 342 / 138

Step 5:
138 can be fit into 342 2 times, resulting in a remainder of 66.
Write down 2 as next digit of the result. 
Result so far: 552.0
If we subtract 276 from 342, we get 66.
Bring next digit (8) of the dividend behind the 66 and repeat the process: 668 / 138

Going ahead to step 6:
668 divided by 138 is 4 with a remainder of 116.
The number 4 becomes the next digit in our result. 
Result so far: 5524.0
The remainder is 116 after subtracting 552 from 668.
Fetch the next digit (4) from the dividend, attach it to 116 and continue: 1164 / 138

Advancing to step 7:
If we divide 1164 by 138, we get 8 and a remainder of 60.
Use 8 as the next digit of our solution. 
Result so far: 55248.0
If we take 1104 away from 1164, we end up with 60.
Fetch the next digit (8) from the dividend, attach it to 60 and continue: 608 / 138

On to step 8:
The number 138 fits into 608 4 times, leaving a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 552484.0
Deduct 552 from 608 and we're left 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.

On to step 9:
138 goes into 560 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 552484.4
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.

Going ahead to step 10:
If we divide 80 by 138, we get 0 and a remainder of 80.
The next digit of our result is 0. 
Result so far: 552484.4
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 11:
When dividing 800 by 138, we get 5 with a remainder of 110.
Record the quotient 5 as the next digit in the result. 
Result so far: 552484.405
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.

Advancing to step 12:
138 can be fit into 1100 7 times, resulting in a remainder of 134.
Use 7 as the next digit of our solution. 
Result so far: 552484.4057
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.

Advancing to step 13:
1340 divided by 138 is 9 with a remainder of 98.
Use 9 as the next digit of our solution. 
Result so far: 552484.40579
Subtract 1242 from 1340 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 14:
When dividing 980 by 138, we get 7 with a remainder of 14.
The next digit of our result is 7. 
Result so far: 552484.405797
Subtract 966 from 980 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 15:
140 divided by 138 is 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 552484.4057971
Subtract 138 from 140 to 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.

Let's proceed to step 16:
138 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 552484.4057971
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 552484.4057971 and a remainder of 2e-08.
