We look at the division of 6550999 by 145 
The aim is to understand the frequency of 145 in 6550999.

Going ahead to step 1:
145 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 145

Advancing to step 2:
If we divide 65 by 145, we get 0 and a remainder of 65.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 65, we end up with 65.
Take the next digit (5) from the dividend and append it to 65, then repeat: 655 / 145

Moving on to step 3:
145 can be fit into 655 4 times, resulting in a remainder of 75.
The next digit of our result is 4. 
Result so far: 4.0
If we take 580 away from 655, we end up with 75.
Bring next digit (0) of the dividend behind the 75 and repeat the process: 750 / 145

Going ahead to step 4:
When dividing 750 by 145, we get 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 45.0
If we subtract 725 from 750, we get 25.
Grab the next digit (9) from the dividend, add it to 25, then carry on: 259 / 145

Going ahead to step 5:
145 can be fit into 259 1 times, resulting in a remainder of 114.
Put 1 as the next digit of the answer. 
Result so far: 451.0
If we subtract 145 from 259, we get 114.
Bring next digit (9) of the dividend behind the 114 and repeat the process: 1149 / 145

Going ahead to step 6:
145 can be fit into 1149 7 times, resulting in a remainder of 134.
The next digit of our result is 7. 
Result so far: 4517.0
The remainder is 134 after subtracting 1015 from 1149.
Grab the next digit (9) from the dividend, add it to 134, then carry on: 1349 / 145

Moving on to step 7:
145 can be fit into 1349 9 times, resulting in a remainder of 44.
Write down 9 as next digit of the result. 
Result so far: 45179.0
If we take 1305 away from 1349, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 8:
145 goes into 440 3 times with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 45179.3
If we subtract 435 from 440, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
145 goes into 50 0 times with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 45179.3
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 10:
The number 145 fits into 500 3 times, leaving a remainder of 65.
The number 3 becomes the next digit in our result. 
Result so far: 45179.303
Deduct 435 from 500 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 11:
The number 145 fits into 650 4 times, leaving a remainder of 70.
Put 4 as the next digit of the answer. 
Result so far: 45179.3034
If we subtract 580 from 650, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 12:
The number 145 fits into 700 4 times, leaving a remainder of 120.
The number 4 becomes the next digit in our result. 
Result so far: 45179.30344
Deduct 580 from 700 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

In conclusion, the division gives 45179.30344 with a balance of 0.00012.
