We look at the division of 57529817 by 598 
The aim is to understand the frequency of 598 in 57529817.

On to step 1:
5 divided by 598 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 598

Moving on to step 2:
If we divide 57 by 598, we get 0 and a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Grab the next digit (5) from the dividend, add it to 57, then carry on: 575 / 598

On to step 3:
If we divide 575 by 598, we get 0 and a remainder of 575.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 575, we end up with 575.
Append the next digit (2) from the dividend to 575 and continue with: 5752 / 598

Moving on to step 4:
5752 divided by 598 is 9 with a remainder of 370.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 5382 from 5752, we get 370.
Grab the next digit (9) from the dividend, add it to 370, then carry on: 3709 / 598

Advancing to step 5:
3709 divided by 598 is 6 with a remainder of 121.
The next digit of our result is 6. 
Result so far: 96.0
Subtract 3588 from 3709 to get 121.
Fetch the next digit (8) from the dividend, attach it to 121 and continue: 1218 / 598

Moving on to step 6:
The number 598 fits into 1218 2 times, leaving a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 962.0
Subtract 1196 from 1218 to get 22.
Take the next digit (1) from the dividend and append it to 22, then repeat: 221 / 598

Moving on to step 7:
The number 598 fits into 221 0 times, leaving a remainder of 221.
Record the quotient 0 as the next digit in the result. 
Result so far: 9620.0
Subtracting 0 from 221 leaves us with 221.
Include the next digit (7) from the dividend after 221, then repeat: 2217 / 598

Let's proceed to step 8:
The number 598 fits into 2217 3 times, leaving a remainder of 423.
The number 3 becomes the next digit in our result. 
Result so far: 96203.0
Subtract 1794 from 2217 to get 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Going ahead to step 9:
598 goes into 4230 7 times with a remainder of 44.
Use 7 as the next digit of our solution. 
Result so far: 96203.7
If we take 4186 away from 4230, 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.

Let's proceed to step 10:
When dividing 440 by 598, we get 0 with a remainder of 440.
Write down 0 as next digit of the result. 
Result so far: 96203.7
If we subtract 0 from 440, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 11:
598 can be fit into 4400 7 times, resulting in a remainder of 214.
The number 7 becomes the next digit in our result. 
Result so far: 96203.707
Deduct 4186 from 4400 and we're left with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Advancing to step 12:
598 can be fit into 2140 3 times, resulting in a remainder of 346.
Record the quotient 3 as the next digit in the result. 
Result so far: 96203.7073
Deduct 1794 from 2140 and we're left with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Advancing to step 13:
If we divide 3460 by 598, we get 5 and a remainder of 470.
The next digit of our result is 5. 
Result so far: 96203.70735
If we take 2990 away from 3460, we end up with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Advancing to step 14:
When dividing 4700 by 598, we get 7 with a remainder of 514.
Record the quotient 7 as the next digit in the result. 
Result so far: 96203.707357
If we subtract 4186 from 4700, we get 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Advancing to step 15:
5140 divided by 598 is 8 with a remainder of 356.
Put 8 as the next digit of the answer. 
Result so far: 96203.7073578
Deduct 4784 from 5140 and we're left with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Let's proceed to step 16:
When dividing 3560 by 598, we get 5 with a remainder of 570.
Record the quotient 5 as the next digit in the result. 
Result so far: 96203.70735785
Deduct 2990 from 3560 and we're left with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

After the division, we end up with 96203.70735785 and a remainder of 5.7e-07.
