We're dividing 683678 by 70 
The aim is to understand the frequency of 70 in 683678.

On to step 1:
70 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 70

Advancing to step 2:
70 goes into 68 0 times with a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Grab the next digit (3) from the dividend, add it to 68, then carry on: 683 / 70

On to step 3:
683 divided by 70 is 9 with a remainder of 53.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 630 from 683 and we're left with 53.
Grab the next digit (6) from the dividend, add it to 53, then carry on: 536 / 70

Let's proceed to step 4:
70 can be fit into 536 7 times, resulting in a remainder of 46.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
The remainder is 46 after subtracting 490 from 536.
Grab the next digit (7) from the dividend, add it to 46, then carry on: 467 / 70

Step 5:
If we divide 467 by 70, we get 6 and a remainder of 47.
Record the quotient 6 as the next digit in the result. 
Result so far: 976.0
Deduct 420 from 467 and we're left with 47.
Fetch the next digit (8) from the dividend, attach it to 47 and continue: 478 / 70

Let's proceed to step 6:
478 divided by 70 is 6 with a remainder of 58.
Record the quotient 6 as the next digit in the result. 
Result so far: 9766.0
The remainder is 58 after subtracting 420 from 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 7:
The number 70 fits into 580 8 times, leaving a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 9766.8
Subtract 560 from 580 to 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.

Going ahead to step 8:
70 goes into 200 2 times with a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 9766.82
The remainder is 60 after subtracting 140 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 9:
600 divided by 70 is 8 with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 9766.828
Subtract 560 from 600 to 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.

Going ahead to step 10:
The number 70 fits into 400 5 times, leaving a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 9766.8285
Deduct 350 from 400 and we're left 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.

Let's proceed to step 11:
The number 70 fits into 500 7 times, leaving a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 9766.82857
Subtract 490 from 500 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
When dividing 100 by 70, we get 1 with a remainder of 30.
The next digit of our result is 1. 
Result so far: 9766.828571
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 13:
If we divide 300 by 70, we get 4 and a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 9766.8285714
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.

Moving on to step 14:
200 divided by 70 is 2 with a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 9766.82857142
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.

The final result is 9766.82857142 with a remainder of 6e-08.
