858512 divided by 70 
The aim is to understand the frequency of 70 in 858512.

On to step 1:
8 divided by 70 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 70

Let's proceed to step 2:
The number 70 fits into 85 1 times, leaving a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 70 from 85 and we're left with 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 70

On to step 3:
158 divided by 70 is 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 18 after subtracting 140 from 158.
Take the next digit (5) from the dividend and append it to 18, then repeat: 185 / 70

Let's proceed to step 4:
70 can be fit into 185 2 times, resulting in a remainder of 45.
The number 2 becomes the next digit in our result. 
Result so far: 122.0
The remainder is 45 after subtracting 140 from 185.
Grab the next digit (1) from the dividend, add it to 45, then carry on: 451 / 70

Let's proceed to step 5:
When dividing 451 by 70, we get 6 with a remainder of 31.
Record the quotient 6 as the next digit in the result. 
Result so far: 1226.0
The remainder is 31 after subtracting 420 from 451.
Append the next digit (2) from the dividend to 31 and continue with: 312 / 70

Advancing to step 6:
When dividing 312 by 70, we get 4 with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 12264.0
Subtract 280 from 312 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 7:
320 divided by 70 is 4 with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 12264.4
Deduct 280 from 320 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 8:
70 goes into 400 5 times with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 12264.45
If we subtract 350 from 400, we 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 9:
If we divide 500 by 70, we get 7 and a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 12264.457
Deduct 490 from 500 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.

Moving on to step 10:
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: 12264.4571
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.

Going ahead to step 11:
70 goes into 300 4 times with a remainder of 20.
The next digit of our result is 4. 
Result so far: 12264.45714
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.

Moving on to step 12:
70 goes into 200 2 times with a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 12264.457142
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.

Let's proceed to step 13:
When dividing 600 by 70, we get 8 with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 12264.4571428
Subtracting 560 from 600 leaves us 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 14:
When dividing 400 by 70, we get 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 12264.45714285
Subtract 350 from 400 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.

The final result is 12264.45714285 with a remainder of 5e-08.
