We look at the division of 598338 by 70 
The aim is to understand the frequency of 70 in 598338.

Advancing to step 1:
The number 70 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 70

Let's proceed to step 2:
If we divide 59 by 70, we get 0 and a remainder of 59.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 59 after subtracting 0 from 59.
Bring next digit (8) of the dividend behind the 59 and repeat the process: 598 / 70

Advancing to step 3:
70 can be fit into 598 8 times, resulting in a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 560 from 598 and we're left with 38.
Fetch the next digit (3) from the dividend, attach it to 38 and continue: 383 / 70

Let's proceed to step 4:
If we divide 383 by 70, we get 5 and a remainder of 33.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
If we take 350 away from 383, we end up with 33.
Take the next digit (3) from the dividend and append it to 33, then repeat: 333 / 70

Step 5:
333 divided by 70 is 4 with a remainder of 53.
Record the quotient 4 as the next digit in the result. 
Result so far: 854.0
The remainder is 53 after subtracting 280 from 333.
Fetch the next digit (8) from the dividend, attach it to 53 and continue: 538 / 70

On to step 6:
70 goes into 538 7 times with a remainder of 48.
Record the quotient 7 as the next digit in the result. 
Result so far: 8547.0
Deduct 490 from 538 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 7:
70 goes into 480 6 times with a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 8547.6
If we take 420 away from 480, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 8:
70 can be fit into 600 8 times, resulting in a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 8547.68
Deduct 560 from 600 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
If we divide 400 by 70, we get 5 and a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 8547.685
Subtracting 350 from 400 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
70 goes into 500 7 times with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 8547.6857
Deduct 490 from 500 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 11:
If we divide 100 by 70, we get 1 and a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 8547.68571
Subtract 70 from 100 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 12:
The number 70 fits into 300 4 times, leaving a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 8547.685714
If we take 280 away from 300, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 13:
The number 70 fits into 200 2 times, leaving a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 8547.6857142
If we subtract 140 from 200, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 14:
600 divided by 70 is 8 with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 8547.68571428
If we subtract 560 from 600, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 8547.68571428, with a leftover of 4e-08.
