We divide 286603 by 70
The aim is to understand the frequency of 70 in 286603.

Step 1:
If we divide 2 by 70, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 70

Let's proceed to step 2:
When dividing 28 by 70, we get 0 with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Grab the next digit (6) from the dividend, add it to 28, then carry on: 286 / 70

Step 3:
70 can be fit into 286 4 times, resulting in a remainder of 6.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 280 from 286, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 70

Step 4:
The number 70 fits into 66 0 times, leaving a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
Subtract 0 from 66 to get 66.
Include the next digit (0) from the dividend after 66, then repeat: 660 / 70

On to step 5:
When dividing 660 by 70, we get 9 with a remainder of 30.
The next digit of our result is 9. 
Result so far: 409.0
Deduct 630 from 660 and we're left with 30.
Bring next digit (3) of the dividend behind the 30 and repeat the process: 303 / 70

Advancing to step 6:
If we divide 303 by 70, we get 4 and a remainder of 23.
Write down 4 as next digit of the result. 
Result so far: 4094.0
Deduct 280 from 303 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 7:
If we divide 230 by 70, we get 3 and a remainder of 20.
The next digit of our result is 3. 
Result so far: 4094.3
If we subtract 210 from 230, we 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.

Going ahead to step 8:
70 goes into 200 2 times with a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 4094.32
Subtracting 140 from 200 leaves us 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.

Step 9:
The number 70 fits into 600 8 times, leaving a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 4094.328
Deduct 560 from 600 and we're left 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.

Going ahead to step 10:
400 divided by 70 is 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 4094.3285
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.

Advancing to step 11:
70 can be fit into 500 7 times, resulting in a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 4094.32857
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.

Moving on to step 12:
If we divide 100 by 70, we get 1 and a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 4094.328571
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.

Going ahead to step 13:
300 divided by 70 is 4 with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 4094.3285714
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.

Let's proceed to step 14:
When dividing 200 by 70, we get 2 with a remainder of 60.
The next digit of our result is 2. 
Result so far: 4094.32857142
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.

In conclusion, the division gives 4094.32857142 with a balance of 6e-08.
