398239 divided by 70 
The aim is to understand the frequency of 70 in 398239.

Step 1:
70 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 70

Advancing to step 2:
When dividing 39 by 70, we get 0 with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Fetch the next digit (8) from the dividend, attach it to 39 and continue: 398 / 70

Advancing to step 3:
If we divide 398 by 70, we get 5 and a remainder of 48.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 350 from 398 leaves us with 48.
Grab the next digit (2) from the dividend, add it to 48, then carry on: 482 / 70

Advancing to step 4:
70 goes into 482 6 times with a remainder of 62.
Write down 6 as next digit of the result. 
Result so far: 56.0
The remainder is 62 after subtracting 420 from 482.
Take the next digit (3) from the dividend and append it to 62, then repeat: 623 / 70

Going ahead to step 5:
70 can be fit into 623 8 times, resulting in a remainder of 63.
Record the quotient 8 as the next digit in the result. 
Result so far: 568.0
If we take 560 away from 623, we end up with 63.
Fetch the next digit (9) from the dividend, attach it to 63 and continue: 639 / 70

Let's proceed to step 6:
639 divided by 70 is 9 with a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 5689.0
If we subtract 630 from 639, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
If we divide 90 by 70, we get 1 and a remainder of 20.
The next digit of our result is 1. 
Result so far: 5689.1
Deduct 70 from 90 and we're left 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.

Let's proceed to step 8:
If we divide 200 by 70, we get 2 and a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 5689.12
Subtract 140 from 200 to 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 9:
70 can be fit into 600 8 times, resulting in a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 5689.128
If we take 560 away from 600, we end up 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.

Moving on to step 10:
70 can be fit into 400 5 times, resulting in a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 5689.1285
The remainder is 50 after subtracting 350 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 11:
The number 70 fits into 500 7 times, leaving a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 5689.12857
Subtracting 490 from 500 leaves us 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.

Step 12:
100 divided by 70 is 1 with a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 5689.128571
If we subtract 70 from 100, we 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.

Moving on to step 13:
The number 70 fits into 300 4 times, leaving a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 5689.1285714
The remainder is 20 after subtracting 280 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 14:
70 goes into 200 2 times with a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 5689.12857142
If we take 140 away from 200, 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.

In conclusion, the division gives 5689.12857142 with a balance of 6e-08.
