We're dividing 620960 by 70 
The aim is to understand the frequency of 70 in 620960.

On to step 1:
When dividing 6 by 70, we get 0 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.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 70

Advancing to step 2:
The number 70 fits into 62 0 times, leaving a remainder of 62.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 62 to get 62.
Grab the next digit (0) from the dividend, add it to 62, then carry on: 620 / 70

Moving on to step 3:
The number 70 fits into 620 8 times, leaving a remainder of 60.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 60 after subtracting 560 from 620.
Grab the next digit (9) from the dividend, add it to 60, then carry on: 609 / 70

Moving on to step 4:
70 goes into 609 8 times with a remainder of 49.
The next digit of our result is 8. 
Result so far: 88.0
If we take 560 away from 609, we end up with 49.
Grab the next digit (6) from the dividend, add it to 49, then carry on: 496 / 70

Step 5:
496 divided by 70 is 7 with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 887.0
Subtracting 490 from 496 leaves us with 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 70

Advancing to step 6:
When dividing 60 by 70, we get 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 8870.0
The remainder is 60 after subtracting 0 from 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 7:
If we divide 600 by 70, we get 8 and a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 8870.8
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.

Step 8:
70 can be fit into 400 5 times, resulting in a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 8870.85
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.

Step 9:
70 goes into 500 7 times with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 8870.857
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.

On to step 10:
70 goes into 100 1 times with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 8870.8571
The remainder is 30 after subtracting 70 from 100.
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 11:
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: 8870.85714
Deduct 280 from 300 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 12:
70 goes into 200 2 times with a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 8870.857142
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.

On to step 13:
The number 70 fits into 600 8 times, leaving a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 8870.8571428
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.

Going ahead to step 14:
70 goes into 400 5 times with a remainder of 50.
The next digit of our result is 5. 
Result so far: 8870.85714285
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.

In conclusion, the division gives 8870.85714285 with a balance of 5e-08.
