We look at the division of 27399718 by 598 
The aim is to understand the frequency of 598 in 27399718.

On to step 1:
598 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 598

Going ahead to step 2:
27 divided by 598 is 0 with a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 27, we end up with 27.
Bring next digit (3) of the dividend behind the 27 and repeat the process: 273 / 598

On to step 3:
598 goes into 273 0 times with a remainder of 273.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 273, we get 273.
Include the next digit (9) from the dividend after 273, then repeat: 2739 / 598

Let's proceed to step 4:
When dividing 2739 by 598, we get 4 with a remainder of 347.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 347 after subtracting 2392 from 2739.
Include the next digit (9) from the dividend after 347, then repeat: 3479 / 598

Going ahead to step 5:
The number 598 fits into 3479 5 times, leaving a remainder of 489.
Put 5 as the next digit of the answer. 
Result so far: 45.0
If we take 2990 away from 3479, we end up with 489.
Bring next digit (7) of the dividend behind the 489 and repeat the process: 4897 / 598

On to step 6:
4897 divided by 598 is 8 with a remainder of 113.
Write down 8 as next digit of the result. 
Result so far: 458.0
The remainder is 113 after subtracting 4784 from 4897.
Take the next digit (1) from the dividend and append it to 113, then repeat: 1131 / 598

Moving on to step 7:
598 can be fit into 1131 1 times, resulting in a remainder of 533.
Use 1 as the next digit of our solution. 
Result so far: 4581.0
If we subtract 598 from 1131, we get 533.
Grab the next digit (8) from the dividend, add it to 533, then carry on: 5338 / 598

On to step 8:
598 goes into 5338 8 times with a remainder of 554.
Write down 8 as next digit of the result. 
Result so far: 45818.0
Subtracting 4784 from 5338 leaves us with 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

On to step 9:
The number 598 fits into 5540 9 times, leaving a remainder of 158.
Put 9 as the next digit of the answer. 
Result so far: 45818.9
If we subtract 5382 from 5540, we get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Advancing to step 10:
598 goes into 1580 2 times with a remainder of 384.
Write down 2 as next digit of the result. 
Result so far: 45818.92
Deduct 1196 from 1580 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 11:
When dividing 3840 by 598, we get 6 with a remainder of 252.
The number 6 becomes the next digit in our result. 
Result so far: 45818.926
Subtracting 3588 from 3840 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Going ahead to step 12:
If we divide 2520 by 598, we get 4 and a remainder of 128.
The next digit of our result is 4. 
Result so far: 45818.9264
Subtracting 2392 from 2520 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 13:
1280 divided by 598 is 2 with a remainder of 84.
Put 2 as the next digit of the answer. 
Result so far: 45818.92642
If we take 1196 away from 1280, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 14:
840 divided by 598 is 1 with a remainder of 242.
Write down 1 as next digit of the result. 
Result so far: 45818.926421
If we subtract 598 from 840, we get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

On to step 15:
If we divide 2420 by 598, we get 4 and a remainder of 28.
The next digit of our result is 4. 
Result so far: 45818.9264214
If we take 2392 away from 2420, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 16:
280 divided by 598 is 0 with a remainder of 280.
The next digit of our result is 0. 
Result so far: 45818.9264214
The remainder is 280 after subtracting 0 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The final outcome is 45818.9264214, with a leftover of 2.8e-07.
