We divide 66474755 by 351
The aim is to understand the frequency of 351 in 66474755.

Moving on to step 1:
351 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 351

Moving on to step 2:
351 can be fit into 66 0 times, resulting in a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Grab the next digit (4) from the dividend, add it to 66, then carry on: 664 / 351

Let's proceed to step 3:
664 divided by 351 is 1 with a remainder of 313.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 351 away from 664, we end up with 313.
Append the next digit (7) from the dividend to 313 and continue with: 3137 / 351

On to step 4:
3137 divided by 351 is 8 with a remainder of 329.
The next digit of our result is 8. 
Result so far: 18.0
If we take 2808 away from 3137, we end up with 329.
Fetch the next digit (4) from the dividend, attach it to 329 and continue: 3294 / 351

On to step 5:
If we divide 3294 by 351, we get 9 and a remainder of 135.
Write down 9 as next digit of the result. 
Result so far: 189.0
The remainder is 135 after subtracting 3159 from 3294.
Fetch the next digit (7) from the dividend, attach it to 135 and continue: 1357 / 351

Going ahead to step 6:
351 can be fit into 1357 3 times, resulting in a remainder of 304.
Use 3 as the next digit of our solution. 
Result so far: 1893.0
If we subtract 1053 from 1357, we get 304.
Take the next digit (5) from the dividend and append it to 304, then repeat: 3045 / 351

Step 7:
If we divide 3045 by 351, we get 8 and a remainder of 237.
Record the quotient 8 as the next digit in the result. 
Result so far: 18938.0
Deduct 2808 from 3045 and we're left with 237.
Append the next digit (5) from the dividend to 237 and continue with: 2375 / 351

Advancing to step 8:
The number 351 fits into 2375 6 times, leaving a remainder of 269.
Use 6 as the next digit of our solution. 
Result so far: 189386.0
If we take 2106 away from 2375, we end up with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Moving on to step 9:
351 goes into 2690 7 times with a remainder of 233.
Use 7 as the next digit of our solution. 
Result so far: 189386.7
If we take 2457 away from 2690, we end up with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Moving on to step 10:
351 can be fit into 2330 6 times, resulting in a remainder of 224.
The number 6 becomes the next digit in our result. 
Result so far: 189386.76
The remainder is 224 after subtracting 2106 from 2330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 11:
When dividing 2240 by 351, we get 6 with a remainder of 134.
Put 6 as the next digit of the answer. 
Result so far: 189386.766
Deduct 2106 from 2240 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

After the division, we end up with 189386.766 and a remainder of 0.0134.
