63401473 ÷ 353 
The aim is to understand the frequency of 353 in 63401473.

Let's proceed to step 1:
If we divide 6 by 353, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 353

Let's proceed to step 2:
353 can be fit into 63 0 times, resulting in a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Take the next digit (4) from the dividend and append it to 63, then repeat: 634 / 353

Step 3:
If we divide 634 by 353, we get 1 and a remainder of 281.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 353 from 634 and we're left with 281.
Bring next digit (0) of the dividend behind the 281 and repeat the process: 2810 / 353

Let's proceed to step 4:
If we divide 2810 by 353, we get 7 and a remainder of 339.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtract 2471 from 2810 to get 339.
Fetch the next digit (1) from the dividend, attach it to 339 and continue: 3391 / 353

Let's proceed to step 5:
The number 353 fits into 3391 9 times, leaving a remainder of 214.
The number 9 becomes the next digit in our result. 
Result so far: 179.0
Subtract 3177 from 3391 to get 214.
Append the next digit (4) from the dividend to 214 and continue with: 2144 / 353

Advancing to step 6:
When dividing 2144 by 353, we get 6 with a remainder of 26.
Use 6 as the next digit of our solution. 
Result so far: 1796.0
Deduct 2118 from 2144 and we're left with 26.
Grab the next digit (7) from the dividend, add it to 26, then carry on: 267 / 353

Step 7:
267 divided by 353 is 0 with a remainder of 267.
The next digit of our result is 0. 
Result so far: 17960.0
The remainder is 267 after subtracting 0 from 267.
Include the next digit (3) from the dividend after 267, then repeat: 2673 / 353

Let's proceed to step 8:
The number 353 fits into 2673 7 times, leaving a remainder of 202.
Use 7 as the next digit of our solution. 
Result so far: 179607.0
The remainder is 202 after subtracting 2471 from 2673.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Moving on to step 9:
If we divide 2020 by 353, we get 5 and a remainder of 255.
Record the quotient 5 as the next digit in the result. 
Result so far: 179607.5
Subtracting 1765 from 2020 leaves us with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Step 10:
353 goes into 2550 7 times with a remainder of 79.
The next digit of our result is 7. 
Result so far: 179607.57
The remainder is 79 after subtracting 2471 from 2550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 11:
353 can be fit into 790 2 times, resulting in a remainder of 84.
Put 2 as the next digit of the answer. 
Result so far: 179607.572
The remainder is 84 after subtracting 706 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 12:
The number 353 fits into 840 2 times, leaving a remainder of 134.
Write down 2 as next digit of the result. 
Result so far: 179607.5722
Deduct 706 from 840 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.

The final outcome is 179607.5722, with a leftover of 0.00134.
