We're dividing 840670 by 70 
The aim is to understand the frequency of 70 in 840670.

Advancing to step 1:
The number 70 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 70

Moving on to step 2:
When dividing 84 by 70, we get 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 70 from 84 and we're left with 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 70

Moving on to step 3:
The number 70 fits into 140 2 times, leaving a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 0 after subtracting 140 from 140.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 70

Moving on to step 4:
70 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 120.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 70

Moving on to step 5:
67 divided by 70 is 0 with a remainder of 67.
The number 0 becomes the next digit in our result. 
Result so far: 1200.0
If we subtract 0 from 67, we get 67.
Bring next digit (0) of the dividend behind the 67 and repeat the process: 670 / 70

On to step 6:
When dividing 670 by 70, we get 9 with a remainder of 40.
Put 9 as the next digit of the answer. 
Result so far: 12009.0
The remainder is 40 after subtracting 630 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 7:
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: 12009.5
Subtract 350 from 400 to 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 8:
500 divided by 70 is 7 with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 12009.57
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 9:
70 can be fit into 100 1 times, resulting in a remainder of 30.
The next digit of our result is 1. 
Result so far: 12009.571
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.

Going ahead to step 10:
When dividing 300 by 70, we get 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 12009.5714
Subtracting 280 from 300 leaves us 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 11:
70 goes into 200 2 times with a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 12009.57142
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.

On to step 12:
600 divided by 70 is 8 with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 12009.571428
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.

On to step 13:
70 goes into 400 5 times with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 12009.5714285
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.

Going ahead to step 14:
500 divided by 70 is 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 12009.57142857
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.

The quotient of the division is 12009.57142857, and the remainder is 1e-08.
