Let's divide 75774060 by 353
The aim is to understand the frequency of 353 in 75774060.

Moving on to step 1:
353 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 353

On to step 2:
The number 353 fits into 75 0 times, leaving a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 75, we end up with 75.
Include the next digit (7) from the dividend after 75, then repeat: 757 / 353

Going ahead to step 3:
If we divide 757 by 353, we get 2 and a remainder of 51.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 706 from 757, we get 51.
Grab the next digit (7) from the dividend, add it to 51, then carry on: 517 / 353

Moving on to step 4:
353 can be fit into 517 1 times, resulting in a remainder of 164.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtract 353 from 517 to get 164.
Bring next digit (4) of the dividend behind the 164 and repeat the process: 1644 / 353

Moving on to step 5:
353 goes into 1644 4 times with a remainder of 232.
Put 4 as the next digit of the answer. 
Result so far: 214.0
Subtract 1412 from 1644 to get 232.
Bring next digit (0) of the dividend behind the 232 and repeat the process: 2320 / 353

Step 6:
The number 353 fits into 2320 6 times, leaving a remainder of 202.
Use 6 as the next digit of our solution. 
Result so far: 2146.0
If we subtract 2118 from 2320, we get 202.
Bring next digit (6) of the dividend behind the 202 and repeat the process: 2026 / 353

Step 7:
2026 divided by 353 is 5 with a remainder of 261.
The next digit of our result is 5. 
Result so far: 21465.0
If we take 1765 away from 2026, we end up with 261.
Bring next digit (0) of the dividend behind the 261 and repeat the process: 2610 / 353

Step 8:
The number 353 fits into 2610 7 times, leaving a remainder of 139.
Use 7 as the next digit of our solution. 
Result so far: 214657.0
Subtract 2471 from 2610 to get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

On to step 9:
When dividing 1390 by 353, we get 3 with a remainder of 331.
The next digit of our result is 3. 
Result so far: 214657.3
If we subtract 1059 from 1390, we get 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Moving on to step 10:
If we divide 3310 by 353, we get 9 and a remainder of 133.
Put 9 as the next digit of the answer. 
Result so far: 214657.39
If we subtract 3177 from 3310, we get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Moving on to step 11:
The number 353 fits into 1330 3 times, leaving a remainder of 271.
Use 3 as the next digit of our solution. 
Result so far: 214657.393
If we subtract 1059 from 1330, we get 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Moving on to step 12:
When dividing 2710 by 353, we get 7 with a remainder of 239.
The number 7 becomes the next digit in our result. 
Result so far: 214657.3937
Subtract 2471 from 2710 to get 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Advancing to step 13:
When dividing 2390 by 353, we get 6 with a remainder of 272.
Write down 6 as next digit of the result. 
Result so far: 214657.39376
The remainder is 272 after subtracting 2118 from 2390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Moving on to step 14:
The number 353 fits into 2720 7 times, leaving a remainder of 249.
The number 7 becomes the next digit in our result. 
Result so far: 214657.393767
The remainder is 249 after subtracting 2471 from 2720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Moving on to step 15:
2490 divided by 353 is 7 with a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 214657.3937677
Subtract 2471 from 2490 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final outcome is 214657.3937677, with a leftover of 1.9e-07.
