786942 ÷ 70 
The aim is to understand the frequency of 70 in 786942.

Going ahead to step 1:
When dividing 7 by 70, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 70

Advancing to step 2:
The number 70 fits into 78 1 times, leaving a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 70 from 78 and we're left with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 70

On to step 3:
The number 70 fits into 86 1 times, leaving a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 70 away from 86, we end up with 16.
Append the next digit (9) from the dividend to 16 and continue with: 169 / 70

Step 4:
The number 70 fits into 169 2 times, leaving a remainder of 29.
Record the quotient 2 as the next digit in the result. 
Result so far: 112.0
Deduct 140 from 169 and we're left with 29.
Include the next digit (4) from the dividend after 29, then repeat: 294 / 70

Advancing to step 5:
70 goes into 294 4 times with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 1124.0
If we take 280 away from 294, we end up with 14.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 70

Advancing to step 6:
When dividing 142 by 70, we get 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 11242.0
If we subtract 140 from 142, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
20 divided by 70 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 11242.0
Deduct 0 from 20 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 8:
70 goes into 200 2 times with a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 11242.02
Subtract 140 from 200 to 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.

Step 9:
The number 70 fits into 600 8 times, leaving a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 11242.028
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.

Advancing 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: 11242.0285
If we take 350 away from 400, we end up 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.

Moving on to step 11:
70 can be fit into 500 7 times, resulting in a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 11242.02857
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:
100 divided by 70 is 1 with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 11242.028571
Subtracting 70 from 100 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 13:
70 can be fit into 300 4 times, resulting in a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 11242.0285714
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.

Going ahead to step 14:
The number 70 fits into 200 2 times, leaving a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 11242.02857142
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.

After the division, we end up with 11242.02857142 and a remainder of 6e-08.
