Let's divide 98020307 by 350
The aim is to understand the frequency of 350 in 98020307.

Going ahead to step 1:
350 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 350

Moving on to step 2:
If we divide 98 by 350, we get 0 and a remainder of 98.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 98 after subtracting 0 from 98.
Take the next digit (0) from the dividend and append it to 98, then repeat: 980 / 350

Going ahead to step 3:
If we divide 980 by 350, we get 2 and a remainder of 280.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 700 from 980 to get 280.
Append the next digit (2) from the dividend to 280 and continue with: 2802 / 350

Going ahead to step 4:
The number 350 fits into 2802 8 times, leaving a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
If we take 2800 away from 2802, we end up with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 350

Going ahead to step 5:
350 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 280.0
Subtracting 0 from 20 leaves us with 20.
Append the next digit (3) from the dividend to 20 and continue with: 203 / 350

On to step 6:
350 can be fit into 203 0 times, resulting in a remainder of 203.
The number 0 becomes the next digit in our result. 
Result so far: 2800.0
If we take 0 away from 203, we end up with 203.
Bring next digit (0) of the dividend behind the 203 and repeat the process: 2030 / 350

On to step 7:
350 can be fit into 2030 5 times, resulting in a remainder of 280.
The number 5 becomes the next digit in our result. 
Result so far: 28005.0
The remainder is 280 after subtracting 1750 from 2030.
Include the next digit (7) from the dividend after 280, then repeat: 2807 / 350

Advancing to step 8:
If we divide 2807 by 350, we get 8 and a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 280058.0
Subtracting 2800 from 2807 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
70 divided by 350 is 0 with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 280058.0
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 10:
When dividing 700 by 350, we get 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 280058.02
If we take 700 away from 700, 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.

Advancing to step 11:
If we divide 0 by 350, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 280058.02
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.

Going ahead to step 12:
If we divide 0 by 350, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 280058.02
Subtract 0 from 0 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.

After the division, we end up with 280058.02 and a remainder of 0.0.
