We look at the division of 38833639 by 350 
The aim is to understand the frequency of 350 in 38833639.

Step 1:
3 divided by 350 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 350

Step 2:
350 can be fit into 38 0 times, resulting in a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Append the next digit (8) from the dividend to 38 and continue with: 388 / 350

Let's proceed to step 3:
The number 350 fits into 388 1 times, leaving a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 350 from 388 and we're left with 38.
Grab the next digit (3) from the dividend, add it to 38, then carry on: 383 / 350

Going ahead to step 4:
383 divided by 350 is 1 with a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we subtract 350 from 383, we get 33.
Include the next digit (3) from the dividend after 33, then repeat: 333 / 350

Step 5:
333 divided by 350 is 0 with a remainder of 333.
Use 0 as the next digit of our solution. 
Result so far: 110.0
If we subtract 0 from 333, we get 333.
Grab the next digit (6) from the dividend, add it to 333, then carry on: 3336 / 350

Step 6:
The number 350 fits into 3336 9 times, leaving a remainder of 186.
Record the quotient 9 as the next digit in the result. 
Result so far: 1109.0
Subtracting 3150 from 3336 leaves us with 186.
Include the next digit (3) from the dividend after 186, then repeat: 1863 / 350

Moving on to step 7:
The number 350 fits into 1863 5 times, leaving a remainder of 113.
The number 5 becomes the next digit in our result. 
Result so far: 11095.0
Deduct 1750 from 1863 and we're left with 113.
Take the next digit (9) from the dividend and append it to 113, then repeat: 1139 / 350

Moving on to step 8:
When dividing 1139 by 350, we get 3 with a remainder of 89.
The number 3 becomes the next digit in our result. 
Result so far: 110953.0
Subtract 1050 from 1139 to get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Moving on to step 9:
If we divide 890 by 350, we get 2 and a remainder of 190.
Use 2 as the next digit of our solution. 
Result so far: 110953.2
Subtracting 700 from 890 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 10:
350 goes into 1900 5 times with a remainder of 150.
The number 5 becomes the next digit in our result. 
Result so far: 110953.25
If we subtract 1750 from 1900, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 11:
1500 divided by 350 is 4 with a remainder of 100.
The number 4 becomes the next digit in our result. 
Result so far: 110953.254
If we take 1400 away from 1500, we end up 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.

Advancing to step 12:
When dividing 1000 by 350, we get 2 with a remainder of 300.
Use 2 as the next digit of our solution. 
Result so far: 110953.2542
Deduct 700 from 1000 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 13:
The number 350 fits into 3000 8 times, leaving a remainder of 200.
The number 8 becomes the next digit in our result. 
Result so far: 110953.25428
The remainder is 200 after subtracting 2800 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 14:
350 goes into 2000 5 times with a remainder of 250.
Put 5 as the next digit of the answer. 
Result so far: 110953.254285
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.

Step 15:
If we divide 2500 by 350, we get 7 and a remainder of 50.
The next digit of our result is 7. 
Result so far: 110953.2542857
If we subtract 2450 from 2500, we 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.

On to step 16:
500 divided by 350 is 1 with a remainder of 150.
The number 1 becomes the next digit in our result. 
Result so far: 110953.25428571
If we subtract 350 from 500, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

The final result is 110953.25428571 with a remainder of 1.5e-07.
