54374854 ÷ 139 
The aim is to understand the frequency of 139 in 54374854.

Going ahead to step 1:
If we divide 5 by 139, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 139

Moving on to step 2:
The number 139 fits into 54 0 times, leaving a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Bring next digit (3) of the dividend behind the 54 and repeat the process: 543 / 139

Let's proceed to step 3:
543 divided by 139 is 3 with a remainder of 126.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 417 from 543 and we're left with 126.
Grab the next digit (7) from the dividend, add it to 126, then carry on: 1267 / 139

Step 4:
139 can be fit into 1267 9 times, resulting in a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 39.0
Subtracting 1251 from 1267 leaves us with 16.
Bring next digit (4) of the dividend behind the 16 and repeat the process: 164 / 139

Advancing to step 5:
When dividing 164 by 139, we get 1 with a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 391.0
Deduct 139 from 164 and we're left with 25.
Include the next digit (8) from the dividend after 25, then repeat: 258 / 139

Advancing to step 6:
139 can be fit into 258 1 times, resulting in a remainder of 119.
Record the quotient 1 as the next digit in the result. 
Result so far: 3911.0
Subtract 139 from 258 to get 119.
Take the next digit (5) from the dividend and append it to 119, then repeat: 1195 / 139

Moving on to step 7:
139 can be fit into 1195 8 times, resulting in a remainder of 83.
The next digit of our result is 8. 
Result so far: 39118.0
The remainder is 83 after subtracting 1112 from 1195.
Bring next digit (4) of the dividend behind the 83 and repeat the process: 834 / 139

On to step 8:
139 goes into 834 6 times with a remainder of 0.
The next digit of our result is 6. 
Result so far: 391186.0
Deduct 834 from 834 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
The number 139 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 391186.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
139 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 391186.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 391186.0, and the remainder is 0.0.
