215941 ÷ 70 
The aim is to understand the frequency of 70 in 215941.

On to step 1:
2 divided by 70 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 70

Advancing to step 2:
21 divided by 70 is 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 70

Advancing to step 3:
70 goes into 215 3 times with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 210 from 215 and we're left with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 70

Going ahead to step 4:
The number 70 fits into 59 0 times, leaving a remainder of 59.
Use 0 as the next digit of our solution. 
Result so far: 30.0
Deduct 0 from 59 and we're left with 59.
Take the next digit (4) from the dividend and append it to 59, then repeat: 594 / 70

Step 5:
70 goes into 594 8 times with a remainder of 34.
Record the quotient 8 as the next digit in the result. 
Result so far: 308.0
If we take 560 away from 594, we end up with 34.
Include the next digit (1) from the dividend after 34, then repeat: 341 / 70

Going ahead to step 6:
The number 70 fits into 341 4 times, leaving a remainder of 61.
The next digit of our result is 4. 
Result so far: 3084.0
If we subtract 280 from 341, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 7:
70 goes into 610 8 times with a remainder of 50.
Write down 8 as next digit of the result. 
Result so far: 3084.8
Subtract 560 from 610 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:
70 goes into 500 7 times with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 3084.87
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.

Let's proceed to step 9:
The number 70 fits into 100 1 times, leaving a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 3084.871
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.

Moving on to step 10:
If we divide 300 by 70, we get 4 and a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 3084.8714
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.

On to step 11:
The number 70 fits into 200 2 times, leaving a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 3084.87142
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.

Advancing to step 12:
600 divided by 70 is 8 with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 3084.871428
The remainder is 40 after subtracting 560 from 600.
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 13:
When dividing 400 by 70, we get 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 3084.8714285
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.

Let's proceed to step 14:
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: 3084.87142857
If we subtract 490 from 500, we 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.

After the division, we end up with 3084.87142857 and a remainder of 1e-08.
