Let's divide 72101273 by 350
The aim is to understand the frequency of 350 in 72101273.

On to step 1:
7 divided by 350 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 350

On to step 2:
350 goes into 72 0 times with a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Append the next digit (1) from the dividend to 72 and continue with: 721 / 350

Advancing to step 3:
350 goes into 721 2 times with a remainder of 21.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 700 from 721, we get 21.
Fetch the next digit (0) from the dividend, attach it to 21 and continue: 210 / 350

On to step 4:
350 can be fit into 210 0 times, resulting in a remainder of 210.
The next digit of our result is 0. 
Result so far: 20.0
The remainder is 210 after subtracting 0 from 210.
Fetch the next digit (1) from the dividend, attach it to 210 and continue: 2101 / 350

On to step 5:
If we divide 2101 by 350, we get 6 and a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 206.0
The remainder is 1 after subtracting 2100 from 2101.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 350

Advancing to step 6:
The number 350 fits into 12 0 times, leaving a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 2060.0
If we take 0 away from 12, we end up with 12.
Fetch the next digit (7) from the dividend, attach it to 12 and continue: 127 / 350

Let's proceed to step 7:
The number 350 fits into 127 0 times, leaving a remainder of 127.
Put 0 as the next digit of the answer. 
Result so far: 20600.0
The remainder is 127 after subtracting 0 from 127.
Bring next digit (3) of the dividend behind the 127 and repeat the process: 1273 / 350

Advancing to step 8:
When dividing 1273 by 350, we get 3 with a remainder of 223.
Write down 3 as next digit of the result. 
Result so far: 206003.0
Subtracting 1050 from 1273 leaves us with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Step 9:
350 can be fit into 2230 6 times, resulting in a remainder of 130.
The number 6 becomes the next digit in our result. 
Result so far: 206003.6
The remainder is 130 after subtracting 2100 from 2230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 10:
When dividing 1300 by 350, we get 3 with a remainder of 250.
Use 3 as the next digit of our solution. 
Result so far: 206003.63
If we subtract 1050 from 1300, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 11:
350 goes into 2500 7 times with a remainder of 50.
The number 7 becomes the next digit in our result. 
Result so far: 206003.637
Subtract 2450 from 2500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 12:
When dividing 500 by 350, we get 1 with a remainder of 150.
Put 1 as the next digit of the answer. 
Result so far: 206003.6371
The remainder is 150 after subtracting 350 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 13:
If we divide 1500 by 350, we get 4 and a remainder of 100.
Write down 4 as next digit of the result. 
Result so far: 206003.63714
Subtracting 1400 from 1500 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 14:
350 can be fit into 1000 2 times, resulting in a remainder of 300.
The next digit of our result is 2. 
Result so far: 206003.637142
Subtract 700 from 1000 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 15:
350 goes into 3000 8 times with a remainder of 200.
Use 8 as the next digit of our solution. 
Result so far: 206003.6371428
If we subtract 2800 from 3000, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 16:
350 can be fit into 2000 5 times, resulting in a remainder of 250.
Use 5 as the next digit of our solution. 
Result so far: 206003.63714285
Subtracting 1750 from 2000 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

The final result is 206003.63714285 with a remainder of 2.5e-07.
