We divide 350116 by 20
The aim is to understand the frequency of 20 in 350116.

Let's proceed to step 1:
3 divided by 20 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 20

On to step 2:
20 can be fit into 35 1 times, resulting in a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 20 from 35 to get 15.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 20

Let's proceed to step 3:
20 goes into 150 7 times with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 17.0
Deduct 140 from 150 and we're left with 10.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 20

Advancing to step 4:
If we divide 101 by 20, we get 5 and a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 175.0
If we subtract 100 from 101, we get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 20

On to step 5:
When dividing 11 by 20, we get 0 with a remainder of 11.
The next digit of our result is 0. 
Result so far: 1750.0
If we subtract 0 from 11, we get 11.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 20

Going ahead to step 6:
20 goes into 116 5 times with a remainder of 16.
Record the quotient 5 as the next digit in the result. 
Result so far: 17505.0
Deduct 100 from 116 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 7:
20 goes into 160 8 times with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 17505.8
Subtract 160 from 160 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 17505.8
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 17505.8
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 17505.8, with a leftover of 0.0.
