We look at the division of 64458557 by 597 
The aim is to understand the frequency of 597 in 64458557.

Advancing to step 1:
6 divided by 597 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 597

Moving on to step 2:
597 goes into 64 0 times with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Include the next digit (4) from the dividend after 64, then repeat: 644 / 597

Going ahead to step 3:
597 goes into 644 1 times with a remainder of 47.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 597 from 644 to get 47.
Append the next digit (5) from the dividend to 47 and continue with: 475 / 597

Step 4:
597 goes into 475 0 times with a remainder of 475.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 475, we end up with 475.
Take the next digit (8) from the dividend and append it to 475, then repeat: 4758 / 597

Advancing to step 5:
597 goes into 4758 7 times with a remainder of 579.
Write down 7 as next digit of the result. 
Result so far: 107.0
The remainder is 579 after subtracting 4179 from 4758.
Take the next digit (5) from the dividend and append it to 579, then repeat: 5795 / 597

Let's proceed to step 6:
597 can be fit into 5795 9 times, resulting in a remainder of 422.
Write down 9 as next digit of the result. 
Result so far: 1079.0
Deduct 5373 from 5795 and we're left with 422.
Grab the next digit (5) from the dividend, add it to 422, then carry on: 4225 / 597

Step 7:
If we divide 4225 by 597, we get 7 and a remainder of 46.
Put 7 as the next digit of the answer. 
Result so far: 10797.0
Subtracting 4179 from 4225 leaves us with 46.
Fetch the next digit (7) from the dividend, attach it to 46 and continue: 467 / 597

Let's proceed to step 8:
When dividing 467 by 597, we get 0 with a remainder of 467.
The number 0 becomes the next digit in our result. 
Result so far: 107970.0
If we subtract 0 from 467, we get 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Moving on to step 9:
597 can be fit into 4670 7 times, resulting in a remainder of 491.
Record the quotient 7 as the next digit in the result. 
Result so far: 107970.7
If we subtract 4179 from 4670, we get 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Moving on to step 10:
597 goes into 4910 8 times with a remainder of 134.
Put 8 as the next digit of the answer. 
Result so far: 107970.78
Deduct 4776 from 4910 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

On to step 11:
597 goes into 1340 2 times with a remainder of 146.
Write down 2 as next digit of the result. 
Result so far: 107970.782
The remainder is 146 after subtracting 1194 from 1340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Moving on to step 12:
If we divide 1460 by 597, we get 2 and a remainder of 266.
Write down 2 as next digit of the result. 
Result so far: 107970.7822
Subtract 1194 from 1460 to get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

The quotient of the division is 107970.7822, and the remainder is 0.00266.
