We're dividing 840316 by 70 
The aim is to understand the frequency of 70 in 840316.

On to step 1:
If we divide 8 by 70, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 70

Advancing to step 2:
If we divide 84 by 70, we get 1 and a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 70 away from 84, we end up with 14.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 70

Going ahead to step 3:
140 divided by 70 is 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 140 from 140, we get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 70

Let's proceed to step 4:
70 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 120.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 70

Advancing to step 5:
31 divided by 70 is 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 1200.0
If we subtract 0 from 31, we get 31.
Append the next digit (6) from the dividend to 31 and continue with: 316 / 70

Moving on to step 6:
If we divide 316 by 70, we get 4 and a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 12004.0
Subtracting 280 from 316 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 7:
360 divided by 70 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 12004.5
The remainder is 10 after subtracting 350 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
When dividing 100 by 70, we get 1 with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 12004.51
The remainder is 30 after subtracting 70 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
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: 12004.514
If we subtract 280 from 300, 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.

Step 10:
70 goes into 200 2 times with a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 12004.5142
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.

Let's proceed to step 11:
600 divided by 70 is 8 with a remainder of 40.
The next digit of our result is 8. 
Result so far: 12004.51428
Subtract 560 from 600 to 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.

Let's proceed to step 12:
If we divide 400 by 70, we get 5 and a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 12004.514285
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.

Advancing to step 13:
If we divide 500 by 70, we get 7 and a remainder of 10.
The next digit of our result is 7. 
Result so far: 12004.5142857
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.

Step 14:
When dividing 100 by 70, we get 1 with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 12004.51428571
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.

After the division, we end up with 12004.51428571 and a remainder of 3e-08.
