We look at the division of 156988 by 70 
The aim is to understand the frequency of 70 in 156988.

Step 1:
1 divided by 70 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 70

Moving on to step 2:
70 goes into 15 0 times with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Bring next digit (6) of the dividend behind the 15 and repeat the process: 156 / 70

Step 3:
The number 70 fits into 156 2 times, leaving a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 140 from 156 to get 16.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 70

Advancing to step 4:
70 can be fit into 169 2 times, resulting in a remainder of 29.
Use 2 as the next digit of our solution. 
Result so far: 22.0
If we take 140 away from 169, we end up with 29.
Take the next digit (8) from the dividend and append it to 29, then repeat: 298 / 70

Going ahead to step 5:
If we divide 298 by 70, we get 4 and a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 224.0
If we subtract 280 from 298, we get 18.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 70

Advancing to step 6:
70 goes into 188 2 times with a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 2242.0
Subtract 140 from 188 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 7:
If we divide 480 by 70, we get 6 and a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 2242.6
If we subtract 420 from 480, 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.

Step 8:
If we divide 600 by 70, we get 8 and a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 2242.68
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
The number 70 fits into 400 5 times, leaving a remainder of 50.
The next digit of our result is 5. 
Result so far: 2242.685
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.
Put 7 as the next digit of the answer. 
Result so far: 2242.6857
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.

Going ahead to step 11:
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: 2242.68571
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.

Moving on 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: 2242.685714
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.

On to step 13:
70 can be fit into 200 2 times, resulting in a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 2242.6857142
Deduct 140 from 200 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.

Going ahead to step 14:
600 divided by 70 is 8 with a remainder of 40.
The next digit of our result is 8. 
Result so far: 2242.68571428
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.

After the division, we end up with 2242.68571428 and a remainder of 4e-08.
