We look at the division of 78265123 by 148 
The aim is to understand the frequency of 148 in 78265123.

Step 1:
When dividing 7 by 148, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 148

Let's proceed to step 2:
The number 148 fits into 78 0 times, leaving a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Fetch the next digit (2) from the dividend, attach it to 78 and continue: 782 / 148

Advancing to step 3:
When dividing 782 by 148, we get 5 with a remainder of 42.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 740 from 782, we get 42.
Append the next digit (6) from the dividend to 42 and continue with: 426 / 148

On to step 4:
When dividing 426 by 148, we get 2 with a remainder of 130.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
If we subtract 296 from 426, we get 130.
Grab the next digit (5) from the dividend, add it to 130, then carry on: 1305 / 148

Let's proceed to step 5:
The number 148 fits into 1305 8 times, leaving a remainder of 121.
The next digit of our result is 8. 
Result so far: 528.0
If we take 1184 away from 1305, we end up with 121.
Include the next digit (1) from the dividend after 121, then repeat: 1211 / 148

Step 6:
If we divide 1211 by 148, we get 8 and a remainder of 27.
The next digit of our result is 8. 
Result so far: 5288.0
If we subtract 1184 from 1211, we get 27.
Bring next digit (2) of the dividend behind the 27 and repeat the process: 272 / 148

Let's proceed to step 7:
When dividing 272 by 148, we get 1 with a remainder of 124.
The next digit of our result is 1. 
Result so far: 52881.0
Subtracting 148 from 272 leaves us with 124.
Fetch the next digit (3) from the dividend, attach it to 124 and continue: 1243 / 148

Let's proceed to step 8:
When dividing 1243 by 148, we get 8 with a remainder of 59.
Write down 8 as next digit of the result. 
Result so far: 528818.0
Deduct 1184 from 1243 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 9:
When dividing 590 by 148, we get 3 with a remainder of 146.
The number 3 becomes the next digit in our result. 
Result so far: 528818.3
Deduct 444 from 590 and we're left with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

On to step 10:
1460 divided by 148 is 9 with a remainder of 128.
Write down 9 as next digit of the result. 
Result so far: 528818.39
Subtracting 1332 from 1460 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 11:
The number 148 fits into 1280 8 times, leaving a remainder of 96.
Put 8 as the next digit of the answer. 
Result so far: 528818.398
Subtracting 1184 from 1280 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 12:
960 divided by 148 is 6 with a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 528818.3986
Subtract 888 from 960 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 13:
148 goes into 720 4 times with a remainder of 128.
Record the quotient 4 as the next digit in the result. 
Result so far: 528818.39864
If we subtract 592 from 720, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 14:
148 can be fit into 1280 8 times, resulting in a remainder of 96.
Write down 8 as next digit of the result. 
Result so far: 528818.398648
Subtract 1184 from 1280 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 15:
148 can be fit into 960 6 times, resulting in a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 528818.3986486
The remainder is 72 after subtracting 888 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 16:
148 can be fit into 720 4 times, resulting in a remainder of 128.
The number 4 becomes the next digit in our result. 
Result so far: 528818.39864864
If we take 592 away from 720, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The final outcome is 528818.39864864, with a leftover of 1.28e-07.
