We look at the division of 89396171 by 148 
The aim is to understand the frequency of 148 in 89396171.

On to step 1:
8 divided by 148 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 148

On to step 2:
When dividing 89 by 148, we get 0 with a remainder of 89.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 89, we end up with 89.
Include the next digit (3) from the dividend after 89, then repeat: 893 / 148

Step 3:
893 divided by 148 is 6 with a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 888 from 893 leaves us with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 148

Moving on to step 4:
148 can be fit into 59 0 times, resulting in a remainder of 59.
Put 0 as the next digit of the answer. 
Result so far: 60.0
Deduct 0 from 59 and we're left with 59.
Take the next digit (6) from the dividend and append it to 59, then repeat: 596 / 148

Moving on to step 5:
When dividing 596 by 148, we get 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 604.0
If we subtract 592 from 596, we get 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 148

On to step 6:
41 divided by 148 is 0 with a remainder of 41.
Write down 0 as next digit of the result. 
Result so far: 6040.0
If we take 0 away from 41, we end up with 41.
Grab the next digit (7) from the dividend, add it to 41, then carry on: 417 / 148

Step 7:
If we divide 417 by 148, we get 2 and a remainder of 121.
The next digit of our result is 2. 
Result so far: 60402.0
Subtract 296 from 417 to get 121.
Bring next digit (1) of the dividend behind the 121 and repeat the process: 1211 / 148

Step 8:
The number 148 fits into 1211 8 times, leaving a remainder of 27.
Record the quotient 8 as the next digit in the result. 
Result so far: 604028.0
Subtracting 1184 from 1211 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 9:
When dividing 270 by 148, we get 1 with a remainder of 122.
Write down 1 as next digit of the result. 
Result so far: 604028.1
If we take 148 away from 270, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Step 10:
If we divide 1220 by 148, we get 8 and a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 604028.18
Subtract 1184 from 1220 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 11:
The number 148 fits into 360 2 times, leaving a remainder of 64.
The next digit of our result is 2. 
Result so far: 604028.182
The remainder is 64 after subtracting 296 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 12:
When dividing 640 by 148, we get 4 with a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 604028.1824
Deduct 592 from 640 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 13:
If we divide 480 by 148, we get 3 and a remainder of 36.
The number 3 becomes the next digit in our result. 
Result so far: 604028.18243
If we subtract 444 from 480, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 14:
The number 148 fits into 360 2 times, leaving a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 604028.182432
If we take 296 away from 360, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 15:
The number 148 fits into 640 4 times, leaving a remainder of 48.
The next digit of our result is 4. 
Result so far: 604028.1824324
Subtract 592 from 640 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 16:
480 divided by 148 is 3 with a remainder of 36.
Write down 3 as next digit of the result. 
Result so far: 604028.18243243
If we subtract 444 from 480, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 604028.18243243 and a remainder of 3.6e-08.
