We look at the division of 157373 by 70 
The aim is to understand the frequency of 70 in 157373.

Moving on to step 1:
If we divide 1 by 70, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 70

Step 2:
70 goes into 15 0 times with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Fetch the next digit (7) from the dividend, attach it to 15 and continue: 157 / 70

On to step 3:
157 divided by 70 is 2 with a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 140 from 157, we get 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 70

On to step 4:
70 goes into 173 2 times with a remainder of 33.
Write down 2 as next digit of the result. 
Result so far: 22.0
Deduct 140 from 173 and we're left with 33.
Grab the next digit (7) from the dividend, add it to 33, then carry on: 337 / 70

Moving on to step 5:
70 can be fit into 337 4 times, resulting in a remainder of 57.
The next digit of our result is 4. 
Result so far: 224.0
Subtract 280 from 337 to get 57.
Grab the next digit (3) from the dividend, add it to 57, then carry on: 573 / 70

Advancing to step 6:
573 divided by 70 is 8 with a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 2248.0
Subtracting 560 from 573 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
If we divide 130 by 70, we get 1 and a remainder of 60.
The next digit of our result is 1. 
Result so far: 2248.1
If we subtract 70 from 130, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 8:
600 divided by 70 is 8 with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 2248.18
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 9:
70 can be fit into 400 5 times, resulting in a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 2248.185
Deduct 350 from 400 and we're left 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.

On to step 10:
When dividing 500 by 70, we get 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 2248.1857
Subtracting 490 from 500 leaves us 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 11:
100 divided by 70 is 1 with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 2248.18571
If we take 70 away from 100, we end up 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.

Advancing to step 12:
70 can be fit into 300 4 times, resulting in a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 2248.185714
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.

Moving on to step 13:
70 can be fit into 200 2 times, resulting in a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 2248.1857142
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.

Advancing to step 14:
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: 2248.18571428
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.

The quotient of the division is 2248.18571428, and the remainder is 4e-08.
