We look at the division of 29078444 by 139 
The aim is to understand the frequency of 139 in 29078444.

Going ahead to step 1:
If we divide 2 by 139, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 139

Going ahead to step 2:
139 goes into 29 0 times with a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 29 and we're left with 29.
Grab the next digit (0) from the dividend, add it to 29, then carry on: 290 / 139

Let's proceed to step 3:
139 can be fit into 290 2 times, resulting in a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 12 after subtracting 278 from 290.
Grab the next digit (7) from the dividend, add it to 12, then carry on: 127 / 139

Let's proceed to step 4:
If we divide 127 by 139, we get 0 and a remainder of 127.
The next digit of our result is 0. 
Result so far: 20.0
Subtract 0 from 127 to get 127.
Include the next digit (8) from the dividend after 127, then repeat: 1278 / 139

Let's proceed to step 5:
If we divide 1278 by 139, we get 9 and a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 209.0
The remainder is 27 after subtracting 1251 from 1278.
Take the next digit (4) from the dividend and append it to 27, then repeat: 274 / 139

Going ahead to step 6:
139 goes into 274 1 times with a remainder of 135.
The next digit of our result is 1. 
Result so far: 2091.0
If we take 139 away from 274, we end up with 135.
Append the next digit (4) from the dividend to 135 and continue with: 1354 / 139

Going ahead to step 7:
If we divide 1354 by 139, we get 9 and a remainder of 103.
Use 9 as the next digit of our solution. 
Result so far: 20919.0
The remainder is 103 after subtracting 1251 from 1354.
Take the next digit (4) from the dividend and append it to 103, then repeat: 1034 / 139

On to step 8:
139 goes into 1034 7 times with a remainder of 61.
The next digit of our result is 7. 
Result so far: 209197.0
Subtracting 973 from 1034 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 9:
610 divided by 139 is 4 with a remainder of 54.
Record the quotient 4 as the next digit in the result. 
Result so far: 209197.4
If we subtract 556 from 610, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 10:
The number 139 fits into 540 3 times, leaving a remainder of 123.
Put 3 as the next digit of the answer. 
Result so far: 209197.43
Subtract 417 from 540 to get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

On to step 11:
1230 divided by 139 is 8 with a remainder of 118.
Record the quotient 8 as the next digit in the result. 
Result so far: 209197.438
Subtract 1112 from 1230 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Advancing to step 12:
If we divide 1180 by 139, we get 8 and a remainder of 68.
Write down 8 as next digit of the result. 
Result so far: 209197.4388
Subtracting 1112 from 1180 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

After the division, we end up with 209197.4388 and a remainder of 0.00068.
