874171 ÷ 70 
The aim is to understand the frequency of 70 in 874171.

On to step 1:
When dividing 8 by 70, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 70

Step 2:
70 can be fit into 87 1 times, resulting in a remainder of 17.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 70 from 87 leaves us with 17.
Include the next digit (4) from the dividend after 17, then repeat: 174 / 70

Moving on to step 3:
70 can be fit into 174 2 times, resulting in a remainder of 34.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 140 from 174 leaves us with 34.
Grab the next digit (1) from the dividend, add it to 34, then carry on: 341 / 70

Going ahead to step 4:
70 can be fit into 341 4 times, resulting in a remainder of 61.
Write down 4 as next digit of the result. 
Result so far: 124.0
The remainder is 61 after subtracting 280 from 341.
Grab the next digit (7) from the dividend, add it to 61, then carry on: 617 / 70

Going ahead to step 5:
The number 70 fits into 617 8 times, leaving a remainder of 57.
Record the quotient 8 as the next digit in the result. 
Result so far: 1248.0
Deduct 560 from 617 and we're left with 57.
Include the next digit (1) from the dividend after 57, then repeat: 571 / 70

Let's proceed to step 6:
The number 70 fits into 571 8 times, leaving a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 12488.0
Deduct 560 from 571 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
If we divide 110 by 70, we get 1 and a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 12488.1
Subtracting 70 from 110 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.

Step 8:
70 goes into 400 5 times with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 12488.15
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.

Going ahead to step 9:
70 goes into 500 7 times with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 12488.157
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.

Let's proceed to step 10:
The number 70 fits into 100 1 times, leaving a remainder of 30.
The next digit of our result is 1. 
Result so far: 12488.1571
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 11:
If we divide 300 by 70, we get 4 and a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 12488.15714
Subtract 280 from 300 to 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.

Let's proceed to step 12:
If we divide 200 by 70, we get 2 and a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 12488.157142
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 13:
70 can be fit into 600 8 times, resulting in a remainder of 40.
The next digit of our result is 8. 
Result so far: 12488.1571428
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.

Let's proceed to step 14:
70 goes into 400 5 times with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 12488.15714285
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.

The final outcome is 12488.15714285, with a leftover of 5e-08.
