55043693 ÷ 145 
The aim is to understand the frequency of 145 in 55043693.

Step 1:
145 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 145

Advancing to step 2:
145 goes into 55 0 times with a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Take the next digit (0) from the dividend and append it to 55, then repeat: 550 / 145

Going ahead to step 3:
If we divide 550 by 145, we get 3 and a remainder of 115.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 435 from 550 to get 115.
Include the next digit (4) from the dividend after 115, then repeat: 1154 / 145

Going ahead to step 4:
145 goes into 1154 7 times with a remainder of 139.
The next digit of our result is 7. 
Result so far: 37.0
Subtracting 1015 from 1154 leaves us with 139.
Append the next digit (3) from the dividend to 139 and continue with: 1393 / 145

Step 5:
145 can be fit into 1393 9 times, resulting in a remainder of 88.
The next digit of our result is 9. 
Result so far: 379.0
Subtracting 1305 from 1393 leaves us with 88.
Grab the next digit (6) from the dividend, add it to 88, then carry on: 886 / 145

On to step 6:
145 can be fit into 886 6 times, resulting in a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 3796.0
If we take 870 away from 886, we end up with 16.
Grab the next digit (9) from the dividend, add it to 16, then carry on: 169 / 145

Step 7:
If we divide 169 by 145, we get 1 and a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 37961.0
If we subtract 145 from 169, we get 24.
Include the next digit (3) from the dividend after 24, then repeat: 243 / 145

Step 8:
145 goes into 243 1 times with a remainder of 98.
Use 1 as the next digit of our solution. 
Result so far: 379611.0
If we subtract 145 from 243, we get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Going ahead to step 9:
980 divided by 145 is 6 with a remainder of 110.
Record the quotient 6 as the next digit in the result. 
Result so far: 379611.6
If we take 870 away from 980, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 10:
1100 divided by 145 is 7 with a remainder of 85.
Use 7 as the next digit of our solution. 
Result so far: 379611.67
Subtract 1015 from 1100 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 11:
145 can be fit into 850 5 times, resulting in a remainder of 125.
The next digit of our result is 5. 
Result so far: 379611.675
Deduct 725 from 850 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Step 12:
1250 divided by 145 is 8 with a remainder of 90.
Put 8 as the next digit of the answer. 
Result so far: 379611.6758
Subtract 1160 from 1250 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 13:
145 goes into 900 6 times with a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 379611.67586
If we take 870 away from 900, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 14:
The number 145 fits into 300 2 times, leaving a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 379611.675862
The remainder is 10 after subtracting 290 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 15:
The number 145 fits into 100 0 times, leaving a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 379611.675862
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 16:
When dividing 1000 by 145, we get 6 with a remainder of 130.
Use 6 as the next digit of our solution. 
Result so far: 379611.67586206
The remainder is 130 after subtracting 870 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

In conclusion, the division gives 379611.67586206 with a balance of 1.3e-07.
