210675 ÷ 70 
The aim is to understand the frequency of 70 in 210675.

Let's proceed to step 1:
The number 70 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 70

Moving on to step 2:
When dividing 21 by 70, we get 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Take the next digit (0) from the dividend and append it to 21, then repeat: 210 / 70

Going ahead to step 3:
The number 70 fits into 210 3 times, leaving a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 210 away from 210, we end up with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 70

Step 4:
The number 70 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 30.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 70

Moving on to step 5:
70 can be fit into 67 0 times, resulting in a remainder of 67.
The next digit of our result is 0. 
Result so far: 300.0
If we take 0 away from 67, we end up with 67.
Grab the next digit (5) from the dividend, add it to 67, then carry on: 675 / 70

Going ahead to step 6:
675 divided by 70 is 9 with a remainder of 45.
Put 9 as the next digit of the answer. 
Result so far: 3009.0
The remainder is 45 after subtracting 630 from 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 7:
When dividing 450 by 70, we get 6 with a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 3009.6
Subtracting 420 from 450 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
The number 70 fits into 300 4 times, leaving a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 3009.64
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 9:
70 goes into 200 2 times with a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 3009.642
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.

On to step 10:
600 divided by 70 is 8 with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 3009.6428
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.

Going ahead to step 11:
The number 70 fits into 400 5 times, leaving a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 3009.64285
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.

Step 12:
70 can be fit into 500 7 times, resulting in a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 3009.642857
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.

Step 13:
The number 70 fits into 100 1 times, leaving a remainder of 30.
The next digit of our result is 1. 
Result so far: 3009.6428571
Deduct 70 from 100 and we're left with 30.
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 14:
300 divided by 70 is 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 3009.64285714
Subtract 280 from 300 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.

The quotient of the division is 3009.64285714, and the remainder is 2e-08.
