We're dividing 398593 by 70 
The aim is to understand the frequency of 70 in 398593.

On to step 1:
The number 70 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 70

On to step 2:
70 goes into 39 0 times with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Grab the next digit (8) from the dividend, add it to 39, then carry on: 398 / 70

Let's proceed to step 3:
70 goes into 398 5 times with a remainder of 48.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 350 from 398 and we're left with 48.
Bring next digit (5) of the dividend behind the 48 and repeat the process: 485 / 70

Going ahead to step 4:
70 can be fit into 485 6 times, resulting in a remainder of 65.
The next digit of our result is 6. 
Result so far: 56.0
Subtracting 420 from 485 leaves us with 65.
Append the next digit (9) from the dividend to 65 and continue with: 659 / 70

Advancing to step 5:
If we divide 659 by 70, we get 9 and a remainder of 29.
The next digit of our result is 9. 
Result so far: 569.0
Deduct 630 from 659 and we're left with 29.
Bring next digit (3) of the dividend behind the 29 and repeat the process: 293 / 70

On to step 6:
70 goes into 293 4 times with a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 5694.0
Subtract 280 from 293 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
70 goes into 130 1 times with a remainder of 60.
The number 1 becomes the next digit in our result. 
Result so far: 5694.1
Subtracting 70 from 130 leaves us 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.

Let's proceed to step 8:
When dividing 600 by 70, we get 8 with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 5694.18
Subtracting 560 from 600 leaves us 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.

Let's proceed to step 9:
When dividing 400 by 70, we get 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 5694.185
If we subtract 350 from 400, we get 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 can be fit into 500 7 times, resulting in a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 5694.1857
The remainder is 10 after subtracting 490 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
If we divide 100 by 70, we get 1 and a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 5694.18571
Deduct 70 from 100 and we're left with 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:
300 divided by 70 is 4 with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 5694.185714
If we subtract 280 from 300, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 13:
The number 70 fits into 200 2 times, leaving a remainder of 60.
The next digit of our result is 2. 
Result so far: 5694.1857142
Deduct 140 from 200 and we're left 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.

Moving on to step 14:
70 goes into 600 8 times with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 5694.18571428
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.

In conclusion, the division gives 5694.18571428 with a balance of 4e-08.
