We look at the division of 70889307 by 350 
The aim is to understand the frequency of 350 in 70889307.

Let's proceed 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
The remainder is 7 after subtracting 0 from 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 350

Moving on to step 2:
350 goes into 70 0 times with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 70 leaves us with 70.
Include the next digit (8) from the dividend after 70, then repeat: 708 / 350

Let's proceed to step 3:
350 can be fit into 708 2 times, resulting in a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 8 after subtracting 700 from 708.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 350

On to step 4:
When dividing 88 by 350, we get 0 with a remainder of 88.
Write down 0 as next digit of the result. 
Result so far: 20.0
Deduct 0 from 88 and we're left with 88.
Bring next digit (9) of the dividend behind the 88 and repeat the process: 889 / 350

Step 5:
If we divide 889 by 350, we get 2 and a remainder of 189.
Use 2 as the next digit of our solution. 
Result so far: 202.0
Subtract 700 from 889 to get 189.
Append the next digit (3) from the dividend to 189 and continue with: 1893 / 350

Advancing to step 6:
350 goes into 1893 5 times with a remainder of 143.
Put 5 as the next digit of the answer. 
Result so far: 2025.0
Deduct 1750 from 1893 and we're left with 143.
Grab the next digit (0) from the dividend, add it to 143, then carry on: 1430 / 350

Step 7:
350 goes into 1430 4 times with a remainder of 30.
Use 4 as the next digit of our solution. 
Result so far: 20254.0
The remainder is 30 after subtracting 1400 from 1430.
Bring next digit (7) of the dividend behind the 30 and repeat the process: 307 / 350

Going ahead to step 8:
When dividing 307 by 350, we get 0 with a remainder of 307.
Record the quotient 0 as the next digit in the result. 
Result so far: 202540.0
If we take 0 away from 307, we end up with 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Step 9:
When dividing 3070 by 350, we get 8 with a remainder of 270.
The next digit of our result is 8. 
Result so far: 202540.8
Deduct 2800 from 3070 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 10:
2700 divided by 350 is 7 with a remainder of 250.
The number 7 becomes the next digit in our result. 
Result so far: 202540.87
If we subtract 2450 from 2700, 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 can be fit into 2500 7 times, resulting in a remainder of 50.
Record the quotient 7 as the next digit in the result. 
Result so far: 202540.877
The remainder is 50 after subtracting 2450 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 202540.877 with a remaining 0.005.
