81164125 ÷ 350 
The aim is to understand the frequency of 350 in 81164125.

Moving on to step 1:
8 divided by 350 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 350

Moving on to step 2:
When dividing 81 by 350, we get 0 with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Take the next digit (1) from the dividend and append it to 81, then repeat: 811 / 350

Moving on to step 3:
When dividing 811 by 350, we get 2 with a remainder of 111.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 700 away from 811, we end up with 111.
Grab the next digit (6) from the dividend, add it to 111, then carry on: 1116 / 350

On to step 4:
1116 divided by 350 is 3 with a remainder of 66.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
If we take 1050 away from 1116, we end up with 66.
Fetch the next digit (4) from the dividend, attach it to 66 and continue: 664 / 350

On to step 5:
When dividing 664 by 350, we get 1 with a remainder of 314.
The next digit of our result is 1. 
Result so far: 231.0
Subtracting 350 from 664 leaves us with 314.
Grab the next digit (1) from the dividend, add it to 314, then carry on: 3141 / 350

Moving on to step 6:
3141 divided by 350 is 8 with a remainder of 341.
Use 8 as the next digit of our solution. 
Result so far: 2318.0
If we subtract 2800 from 3141, we get 341.
Include the next digit (2) from the dividend after 341, then repeat: 3412 / 350

On to step 7:
If we divide 3412 by 350, we get 9 and a remainder of 262.
Write down 9 as next digit of the result. 
Result so far: 23189.0
The remainder is 262 after subtracting 3150 from 3412.
Take the next digit (5) from the dividend and append it to 262, then repeat: 2625 / 350

Moving on to step 8:
2625 divided by 350 is 7 with a remainder of 175.
Use 7 as the next digit of our solution. 
Result so far: 231897.0
The remainder is 175 after subtracting 2450 from 2625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 9:
350 can be fit into 1750 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 231897.5
If we take 1750 away from 1750, 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 10:
350 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 231897.5
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.

Step 11:
When dividing 0 by 350, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 231897.5
If we subtract 0 from 0, we 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.

In conclusion, the division gives 231897.5 with a balance of 0.0.
