We're dividing 81443503 by 597 
The aim is to understand the frequency of 597 in 81443503.

On to step 1:
597 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 597

Advancing to step 2:
81 divided by 597 is 0 with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Take the next digit (4) from the dividend and append it to 81, then repeat: 814 / 597

Let's proceed to step 3:
814 divided by 597 is 1 with a remainder of 217.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 217 after subtracting 597 from 814.
Grab the next digit (4) from the dividend, add it to 217, then carry on: 2174 / 597

On to step 4:
2174 divided by 597 is 3 with a remainder of 383.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 1791 from 2174 leaves us with 383.
Fetch the next digit (3) from the dividend, attach it to 383 and continue: 3833 / 597

Advancing to step 5:
597 goes into 3833 6 times with a remainder of 251.
The next digit of our result is 6. 
Result so far: 136.0
If we take 3582 away from 3833, we end up with 251.
Bring next digit (5) of the dividend behind the 251 and repeat the process: 2515 / 597

Advancing to step 6:
The number 597 fits into 2515 4 times, leaving a remainder of 127.
Use 4 as the next digit of our solution. 
Result so far: 1364.0
Subtracting 2388 from 2515 leaves us with 127.
Fetch the next digit (0) from the dividend, attach it to 127 and continue: 1270 / 597

Step 7:
The number 597 fits into 1270 2 times, leaving a remainder of 76.
Write down 2 as next digit of the result. 
Result so far: 13642.0
If we take 1194 away from 1270, we end up with 76.
Grab the next digit (3) from the dividend, add it to 76, then carry on: 763 / 597

Advancing to step 8:
597 goes into 763 1 times with a remainder of 166.
Record the quotient 1 as the next digit in the result. 
Result so far: 136421.0
Deduct 597 from 763 and we're left with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

On to step 9:
When dividing 1660 by 597, we get 2 with a remainder of 466.
Use 2 as the next digit of our solution. 
Result so far: 136421.2
Subtracting 1194 from 1660 leaves us with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Moving on to step 10:
597 can be fit into 4660 7 times, resulting in a remainder of 481.
The next digit of our result is 7. 
Result so far: 136421.27
If we subtract 4179 from 4660, we get 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

Step 11:
597 goes into 4810 8 times with a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 136421.278
Subtract 4776 from 4810 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 12:
597 goes into 340 0 times with a remainder of 340.
Record the quotient 0 as the next digit in the result. 
Result so far: 136421.278
If we subtract 0 from 340, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 13:
597 can be fit into 3400 5 times, resulting in a remainder of 415.
The next digit of our result is 5. 
Result so far: 136421.27805
Deduct 2985 from 3400 and we're left with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Moving on to step 14:
If we divide 4150 by 597, we get 6 and a remainder of 568.
Write down 6 as next digit of the result. 
Result so far: 136421.278056
Deduct 3582 from 4150 and we're left with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Moving on to step 15:
597 goes into 5680 9 times with a remainder of 307.
Put 9 as the next digit of the answer. 
Result so far: 136421.2780569
Subtracting 5373 from 5680 leaves us with 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Step 16:
The number 597 fits into 3070 5 times, leaving a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 136421.27805695
If we take 2985 away from 3070, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

In conclusion, the division gives 136421.27805695 with a balance of 8.5e-08.
