30978372 divided by 598 
The aim is to understand the frequency of 598 in 30978372.

Let's proceed to step 1:
If we divide 3 by 598, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 598

Moving on to step 2:
When dividing 30 by 598, we get 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Grab the next digit (9) from the dividend, add it to 30, then carry on: 309 / 598

Moving on to step 3:
If we divide 309 by 598, we get 0 and a remainder of 309.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 309 after subtracting 0 from 309.
Grab the next digit (7) from the dividend, add it to 309, then carry on: 3097 / 598

On to step 4:
If we divide 3097 by 598, we get 5 and a remainder of 107.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 107 after subtracting 2990 from 3097.
Bring next digit (8) of the dividend behind the 107 and repeat the process: 1078 / 598

Let's proceed to step 5:
598 can be fit into 1078 1 times, resulting in a remainder of 480.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Subtracting 598 from 1078 leaves us with 480.
Grab the next digit (3) from the dividend, add it to 480, then carry on: 4803 / 598

On to step 6:
4803 divided by 598 is 8 with a remainder of 19.
The number 8 becomes the next digit in our result. 
Result so far: 518.0
Subtracting 4784 from 4803 leaves us with 19.
Bring next digit (7) of the dividend behind the 19 and repeat the process: 197 / 598

Let's proceed to step 7:
197 divided by 598 is 0 with a remainder of 197.
The next digit of our result is 0. 
Result so far: 5180.0
The remainder is 197 after subtracting 0 from 197.
Bring next digit (2) of the dividend behind the 197 and repeat the process: 1972 / 598

Moving on to step 8:
1972 divided by 598 is 3 with a remainder of 178.
Record the quotient 3 as the next digit in the result. 
Result so far: 51803.0
If we subtract 1794 from 1972, we get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Advancing to step 9:
598 goes into 1780 2 times with a remainder of 584.
Write down 2 as next digit of the result. 
Result so far: 51803.2
Deduct 1196 from 1780 and we're left with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

On to step 10:
598 can be fit into 5840 9 times, resulting in a remainder of 458.
Use 9 as the next digit of our solution. 
Result so far: 51803.29
Subtracting 5382 from 5840 leaves us with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

On to step 11:
4580 divided by 598 is 7 with a remainder of 394.
Record the quotient 7 as the next digit in the result. 
Result so far: 51803.297
If we subtract 4186 from 4580, we get 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Going ahead to step 12:
If we divide 3940 by 598, we get 6 and a remainder of 352.
Write down 6 as next digit of the result. 
Result so far: 51803.2976
If we take 3588 away from 3940, we end up with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Let's proceed to step 13:
When dividing 3520 by 598, we get 5 with a remainder of 530.
Write down 5 as next digit of the result. 
Result so far: 51803.29765
The remainder is 530 after subtracting 2990 from 3520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Step 14:
If we divide 5300 by 598, we get 8 and a remainder of 516.
Put 8 as the next digit of the answer. 
Result so far: 51803.297658
Subtracting 4784 from 5300 leaves us with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Moving on to step 15:
When dividing 5160 by 598, we get 8 with a remainder of 376.
Use 8 as the next digit of our solution. 
Result so far: 51803.2976588
The remainder is 376 after subtracting 4784 from 5160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Our division results in 51803.2976588 with a remaining 3.76e-06.
