We look at the division of 19399487 by 148 
The aim is to understand the frequency of 148 in 19399487.

Let's proceed to step 1:
1 divided by 148 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 148

Advancing to step 2:
148 can be fit into 19 0 times, resulting in a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Bring next digit (3) of the dividend behind the 19 and repeat the process: 193 / 148

Let's proceed to step 3:
193 divided by 148 is 1 with a remainder of 45.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 148 from 193 to get 45.
Grab the next digit (9) from the dividend, add it to 45, then carry on: 459 / 148

Going ahead to step 4:
459 divided by 148 is 3 with a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 13.0
The remainder is 15 after subtracting 444 from 459.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 148

Step 5:
148 can be fit into 159 1 times, resulting in a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 131.0
Subtracting 148 from 159 leaves us with 11.
Fetch the next digit (4) from the dividend, attach it to 11 and continue: 114 / 148

On to step 6:
148 goes into 114 0 times with a remainder of 114.
The next digit of our result is 0. 
Result so far: 1310.0
If we take 0 away from 114, we end up with 114.
Grab the next digit (8) from the dividend, add it to 114, then carry on: 1148 / 148

Moving on to step 7:
The number 148 fits into 1148 7 times, leaving a remainder of 112.
Use 7 as the next digit of our solution. 
Result so far: 13107.0
Deduct 1036 from 1148 and we're left with 112.
Grab the next digit (7) from the dividend, add it to 112, then carry on: 1127 / 148

Moving on to step 8:
148 can be fit into 1127 7 times, resulting in a remainder of 91.
Write down 7 as next digit of the result. 
Result so far: 131077.0
Deduct 1036 from 1127 and we're left with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Step 9:
148 can be fit into 910 6 times, resulting in a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 131077.6
Subtracting 888 from 910 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 10:
If we divide 220 by 148, we get 1 and a remainder of 72.
The next digit of our result is 1. 
Result so far: 131077.61
If we take 148 away from 220, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 11:
148 can be fit into 720 4 times, resulting in a remainder of 128.
Write down 4 as next digit of the result. 
Result so far: 131077.614
Subtracting 592 from 720 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.

Moving on to step 12:
The number 148 fits into 1280 8 times, leaving a remainder of 96.
The next digit of our result is 8. 
Result so far: 131077.6148
Deduct 1184 from 1280 and we're left 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.

Let's proceed to step 13:
960 divided by 148 is 6 with a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 131077.61486
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 14:
If we divide 720 by 148, we get 4 and a remainder of 128.
Write down 4 as next digit of the result. 
Result so far: 131077.614864
Deduct 592 from 720 and we're left 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.

Step 15:
148 goes into 1280 8 times with a remainder of 96.
Record the quotient 8 as the next digit in the result. 
Result so far: 131077.6148648
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 16:
148 goes into 960 6 times with a remainder of 72.
The next digit of our result is 6. 
Result so far: 131077.61486486
Deduct 888 from 960 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

After the division, we end up with 131077.61486486 and a remainder of 7.2e-08.
