87406875 ÷ 350 
The aim is to understand the frequency of 350 in 87406875.

Moving on to step 1:
The number 350 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 350

Let's proceed to step 2:
350 can be fit into 87 0 times, resulting in a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Include the next digit (4) from the dividend after 87, then repeat: 874 / 350

Going ahead to step 3:
350 can be fit into 874 2 times, resulting in a remainder of 174.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 700 from 874 to get 174.
Append the next digit (0) from the dividend to 174 and continue with: 1740 / 350

Going ahead to step 4:
350 goes into 1740 4 times with a remainder of 340.
Write down 4 as next digit of the result. 
Result so far: 24.0
If we take 1400 away from 1740, we end up with 340.
Bring next digit (6) of the dividend behind the 340 and repeat the process: 3406 / 350

Going ahead to step 5:
3406 divided by 350 is 9 with a remainder of 256.
Use 9 as the next digit of our solution. 
Result so far: 249.0
If we take 3150 away from 3406, we end up with 256.
Take the next digit (8) from the dividend and append it to 256, then repeat: 2568 / 350

On to step 6:
350 can be fit into 2568 7 times, resulting in a remainder of 118.
Record the quotient 7 as the next digit in the result. 
Result so far: 2497.0
Subtracting 2450 from 2568 leaves us with 118.
Append the next digit (7) from the dividend to 118 and continue with: 1187 / 350

Going ahead to step 7:
If we divide 1187 by 350, we get 3 and a remainder of 137.
Use 3 as the next digit of our solution. 
Result so far: 24973.0
If we take 1050 away from 1187, we end up with 137.
Bring next digit (5) of the dividend behind the 137 and repeat the process: 1375 / 350

Step 8:
If we divide 1375 by 350, we get 3 and a remainder of 325.
The next digit of our result is 3. 
Result so far: 249733.0
Subtracting 1050 from 1375 leaves us with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Going ahead to step 9:
3250 divided by 350 is 9 with a remainder of 100.
Use 9 as the next digit of our solution. 
Result so far: 249733.9
Deduct 3150 from 3250 and we're left 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 10:
350 can be fit into 1000 2 times, resulting in a remainder of 300.
The number 2 becomes the next digit in our result. 
Result so far: 249733.92
If we subtract 700 from 1000, we 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.

Let's proceed to step 11:
If we divide 3000 by 350, we get 8 and a remainder of 200.
Write down 8 as next digit of the result. 
Result so far: 249733.928
Subtract 2800 from 3000 to 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 12:
2000 divided by 350 is 5 with a remainder of 250.
Record the quotient 5 as the next digit in the result. 
Result so far: 249733.9285
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.

Let's proceed to step 13:
350 goes into 2500 7 times with a remainder of 50.
Use 7 as the next digit of our solution. 
Result so far: 249733.92857
Deduct 2450 from 2500 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 14:
350 can be fit into 500 1 times, resulting in a remainder of 150.
Use 1 as the next digit of our solution. 
Result so far: 249733.928571
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.

Moving on to step 15:
The number 350 fits into 1500 4 times, leaving a remainder of 100.
Put 4 as the next digit of the answer. 
Result so far: 249733.9285714
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 16:
The number 350 fits into 1000 2 times, leaving a remainder of 300.
Write down 2 as next digit of the result. 
Result so far: 249733.92857142
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.

The final result is 249733.92857142 with a remainder of 3e-07.
