We're dividing 76278814 by 139 
The aim is to understand the frequency of 139 in 76278814.

On to step 1:
When dividing 7 by 139, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 139

On to step 2:
When dividing 76 by 139, we get 0 with 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.
Bring next digit (2) of the dividend behind the 76 and repeat the process: 762 / 139

Moving on to step 3:
When dividing 762 by 139, we get 5 with a remainder of 67.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 695 from 762, we get 67.
Take the next digit (7) from the dividend and append it to 67, then repeat: 677 / 139

Moving on to step 4:
139 can be fit into 677 4 times, resulting in a remainder of 121.
Put 4 as the next digit of the answer. 
Result so far: 54.0
If we subtract 556 from 677, we get 121.
Include the next digit (8) from the dividend after 121, then repeat: 1218 / 139

Let's proceed to step 5:
1218 divided by 139 is 8 with a remainder of 106.
Record the quotient 8 as the next digit in the result. 
Result so far: 548.0
Subtracting 1112 from 1218 leaves us with 106.
Fetch the next digit (8) from the dividend, attach it to 106 and continue: 1068 / 139

Advancing to step 6:
139 goes into 1068 7 times with a remainder of 95.
Write down 7 as next digit of the result. 
Result so far: 5487.0
Subtracting 973 from 1068 leaves us with 95.
Take the next digit (1) from the dividend and append it to 95, then repeat: 951 / 139

Going ahead to step 7:
139 goes into 951 6 times with a remainder of 117.
The next digit of our result is 6. 
Result so far: 54876.0
If we subtract 834 from 951, we get 117.
Append the next digit (4) from the dividend to 117 and continue with: 1174 / 139

On to step 8:
The number 139 fits into 1174 8 times, leaving a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 548768.0
If we subtract 1112 from 1174, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 9:
If we divide 620 by 139, we get 4 and a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 548768.4
Subtract 556 from 620 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 10:
139 can be fit into 640 4 times, resulting in a remainder of 84.
The number 4 becomes the next digit in our result. 
Result so far: 548768.44
If we subtract 556 from 640, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The quotient of the division is 548768.44, and the remainder is 0.084.
