We're dividing 287673 by 70 
The aim is to understand the frequency of 70 in 287673.

On to step 1:
If we divide 2 by 70, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 70

Moving on to step 2:
The number 70 fits into 28 0 times, leaving a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Grab the next digit (7) from the dividend, add it to 28, then carry on: 287 / 70

Step 3:
70 can be fit into 287 4 times, resulting in a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 280 from 287 to get 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 70

Advancing to step 4:
If we divide 76 by 70, we get 1 and a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 41.0
The remainder is 6 after subtracting 70 from 76.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 70

On to step 5:
If we divide 67 by 70, we get 0 and a remainder of 67.
The number 0 becomes the next digit in our result. 
Result so far: 410.0
Subtracting 0 from 67 leaves us with 67.
Include the next digit (3) from the dividend after 67, then repeat: 673 / 70

Going ahead to step 6:
If we divide 673 by 70, we get 9 and a remainder of 43.
Write down 9 as next digit of the result. 
Result so far: 4109.0
The remainder is 43 after subtracting 630 from 673.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 7:
430 divided by 70 is 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 4109.6
Deduct 420 from 430 and we're left 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.

Step 8:
If we divide 100 by 70, we get 1 and a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 4109.61
If we subtract 70 from 100, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
300 divided by 70 is 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 4109.614
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.

Moving on to step 10:
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: 4109.6142
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.

Going ahead to step 11:
When dividing 600 by 70, we get 8 with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 4109.61428
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 12:
70 can be fit into 400 5 times, resulting in a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 4109.614285
The remainder is 50 after subtracting 350 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 13:
The number 70 fits into 500 7 times, leaving a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 4109.6142857
If we take 490 away from 500, we end up 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.

Moving on to step 14:
When dividing 100 by 70, we get 1 with a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 4109.61428571
If we take 70 away from 100, we end up 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.

The quotient of the division is 4109.61428571, and the remainder is 3e-08.
