515276 ÷ 70 
The aim is to understand the frequency of 70 in 515276.

Step 1:
If we divide 5 by 70, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 70

On to step 2:
51 divided by 70 is 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Grab the next digit (5) from the dividend, add it to 51, then carry on: 515 / 70

Let's proceed to step 3:
515 divided by 70 is 7 with a remainder of 25.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 490 from 515, we get 25.
Append the next digit (2) from the dividend to 25 and continue with: 252 / 70

Let's proceed to step 4:
70 goes into 252 3 times with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 73.0
If we take 210 away from 252, we end up with 42.
Take the next digit (7) from the dividend and append it to 42, then repeat: 427 / 70

On to step 5:
70 can be fit into 427 6 times, resulting in a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 736.0
Deduct 420 from 427 and we're left with 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 70

Step 6:
76 divided by 70 is 1 with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 7361.0
If we take 70 away from 76, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
The number 70 fits into 60 0 times, leaving a remainder of 60.
The next digit of our result is 0. 
Result so far: 7361.0
Deduct 0 from 60 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.

Step 8:
600 divided by 70 is 8 with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 7361.08
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.

Let's proceed to step 9:
If we divide 400 by 70, we get 5 and a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 7361.085
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.

Step 10:
70 can be fit into 500 7 times, resulting in a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 7361.0857
If we subtract 490 from 500, we 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.

Step 11:
70 goes into 100 1 times with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 7361.08571
Deduct 70 from 100 and we're left 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.

Step 12:
If we divide 300 by 70, we get 4 and a remainder of 20.
The next digit of our result is 4. 
Result so far: 7361.085714
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 13:
200 divided by 70 is 2 with a remainder of 60.
The next digit of our result is 2. 
Result so far: 7361.0857142
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.

Advancing to step 14:
70 goes into 600 8 times with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 7361.08571428
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.

The quotient of the division is 7361.08571428, and the remainder is 4e-08.
