57245575 divided by 145 
The aim is to understand the frequency of 145 in 57245575.

Moving on to step 1:
5 divided by 145 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 145

On to step 2:
145 can be fit into 57 0 times, resulting in a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Take the next digit (2) from the dividend and append it to 57, then repeat: 572 / 145

Moving on to step 3:
145 can be fit into 572 3 times, resulting in a remainder of 137.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 435 away from 572, we end up with 137.
Include the next digit (4) from the dividend after 137, then repeat: 1374 / 145

Advancing to step 4:
1374 divided by 145 is 9 with a remainder of 69.
The next digit of our result is 9. 
Result so far: 39.0
The remainder is 69 after subtracting 1305 from 1374.
Grab the next digit (5) from the dividend, add it to 69, then carry on: 695 / 145

Advancing to step 5:
145 can be fit into 695 4 times, resulting in a remainder of 115.
Use 4 as the next digit of our solution. 
Result so far: 394.0
The remainder is 115 after subtracting 580 from 695.
Include the next digit (5) from the dividend after 115, then repeat: 1155 / 145

Moving on to step 6:
The number 145 fits into 1155 7 times, leaving a remainder of 140.
Write down 7 as next digit of the result. 
Result so far: 3947.0
Subtract 1015 from 1155 to get 140.
Fetch the next digit (7) from the dividend, attach it to 140 and continue: 1407 / 145

On to step 7:
145 goes into 1407 9 times with a remainder of 102.
Put 9 as the next digit of the answer. 
Result so far: 39479.0
Deduct 1305 from 1407 and we're left with 102.
Take the next digit (5) from the dividend and append it to 102, then repeat: 1025 / 145

Let's proceed to step 8:
If we divide 1025 by 145, we get 7 and a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 394797.0
If we subtract 1015 from 1025, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
If we divide 100 by 145, we get 0 and a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 394797.0
Subtracting 0 from 100 leaves us 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.

Going ahead to step 10:
145 can be fit into 1000 6 times, resulting in a remainder of 130.
Put 6 as the next digit of the answer. 
Result so far: 394797.06
If we subtract 870 from 1000, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 11:
145 goes into 1300 8 times with a remainder of 140.
The next digit of our result is 8. 
Result so far: 394797.068
The remainder is 140 after subtracting 1160 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 12:
145 can be fit into 1400 9 times, resulting in a remainder of 95.
Write down 9 as next digit of the result. 
Result so far: 394797.0689
The remainder is 95 after subtracting 1305 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Step 13:
If we divide 950 by 145, we get 6 and a remainder of 80.
Write down 6 as next digit of the result. 
Result so far: 394797.06896
If we subtract 870 from 950, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 14:
145 goes into 800 5 times with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 394797.068965
If we take 725 away from 800, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 15:
When dividing 750 by 145, we get 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 394797.0689655
Deduct 725 from 750 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

In conclusion, the division gives 394797.0689655 with a balance of 2.5e-07.
