Let's divide 990144 by 148
The aim is to understand the frequency of 148 in 990144.

Going ahead to step 1:
148 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 148

Let's proceed to step 2:
When dividing 99 by 148, we get 0 with a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 99 to get 99.
Take the next digit (0) from the dividend and append it to 99, then repeat: 990 / 148

Step 3:
148 can be fit into 990 6 times, resulting in a remainder of 102.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 888 from 990 and we're left with 102.
Fetch the next digit (1) from the dividend, attach it to 102 and continue: 1021 / 148

Moving on to step 4:
When dividing 1021 by 148, we get 6 with a remainder of 133.
Put 6 as the next digit of the answer. 
Result so far: 66.0
Deduct 888 from 1021 and we're left with 133.
Grab the next digit (4) from the dividend, add it to 133, then carry on: 1334 / 148

Let's proceed to step 5:
If we divide 1334 by 148, we get 9 and a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 669.0
If we take 1332 away from 1334, we end up with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 148

Advancing to step 6:
24 divided by 148 is 0 with a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 6690.0
Subtract 0 from 24 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 7:
If we divide 240 by 148, we get 1 and a remainder of 92.
Write down 1 as next digit of the result. 
Result so far: 6690.1
Subtracting 148 from 240 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 8:
If we divide 920 by 148, we get 6 and a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 6690.16
If we subtract 888 from 920, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 9:
When dividing 320 by 148, we get 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 6690.162
The remainder is 24 after subtracting 296 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
If we divide 240 by 148, we get 1 and a remainder of 92.
Write down 1 as next digit of the result. 
Result so far: 6690.1621
If we take 148 away from 240, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 11:
When dividing 920 by 148, we get 6 with a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 6690.16216
If we take 888 away from 920, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 12:
320 divided by 148 is 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 6690.162162
If we subtract 296 from 320, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 13:
When dividing 240 by 148, we get 1 with a remainder of 92.
Record the quotient 1 as the next digit in the result. 
Result so far: 6690.1621621
Subtract 148 from 240 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 14:
920 divided by 148 is 6 with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 6690.16216216
If we take 888 away from 920, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 6690.16216216 with a balance of 3.2e-08.
