Let's divide 17088945 by 351
The aim is to understand the frequency of 351 in 17088945.

Step 1:
351 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 351

Going ahead to step 2:
351 goes into 17 0 times with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Bring next digit (0) of the dividend behind the 17 and repeat the process: 170 / 351

Step 3:
When dividing 170 by 351, we get 0 with a remainder of 170.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 170 and we're left with 170.
Take the next digit (8) from the dividend and append it to 170, then repeat: 1708 / 351

Let's proceed to step 4:
The number 351 fits into 1708 4 times, leaving a remainder of 304.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 1404 from 1708 and we're left with 304.
Fetch the next digit (8) from the dividend, attach it to 304 and continue: 3048 / 351

Moving on to step 5:
When dividing 3048 by 351, we get 8 with a remainder of 240.
The next digit of our result is 8. 
Result so far: 48.0
The remainder is 240 after subtracting 2808 from 3048.
Append the next digit (9) from the dividend to 240 and continue with: 2409 / 351

Moving on to step 6:
If we divide 2409 by 351, we get 6 and a remainder of 303.
Use 6 as the next digit of our solution. 
Result so far: 486.0
If we take 2106 away from 2409, we end up with 303.
Grab the next digit (4) from the dividend, add it to 303, then carry on: 3034 / 351

Moving on to step 7:
351 can be fit into 3034 8 times, resulting in a remainder of 226.
Write down 8 as next digit of the result. 
Result so far: 4868.0
If we take 2808 away from 3034, we end up with 226.
Take the next digit (5) from the dividend and append it to 226, then repeat: 2265 / 351

Moving on to step 8:
The number 351 fits into 2265 6 times, leaving a remainder of 159.
Use 6 as the next digit of our solution. 
Result so far: 48686.0
The remainder is 159 after subtracting 2106 from 2265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Moving on to step 9:
If we divide 1590 by 351, we get 4 and a remainder of 186.
The number 4 becomes the next digit in our result. 
Result so far: 48686.4
Subtract 1404 from 1590 to get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Going ahead to step 10:
351 goes into 1860 5 times with a remainder of 105.
Write down 5 as next digit of the result. 
Result so far: 48686.45
Subtract 1755 from 1860 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Let's proceed to step 11:
If we divide 1050 by 351, we get 2 and a remainder of 348.
The next digit of our result is 2. 
Result so far: 48686.452
The remainder is 348 after subtracting 702 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

On to step 12:
The number 351 fits into 3480 9 times, leaving a remainder of 321.
Put 9 as the next digit of the answer. 
Result so far: 48686.4529
Subtracting 3159 from 3480 leaves us with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Going ahead to step 13:
3210 divided by 351 is 9 with a remainder of 51.
The number 9 becomes the next digit in our result. 
Result so far: 48686.45299
If we subtract 3159 from 3210, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Our division results in 48686.45299 with a remaining 5.1e-05.
