Let's divide 53278861 by 355
The aim is to understand the frequency of 355 in 53278861.

Step 1:
If we divide 5 by 355, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 355

Going ahead to step 2:
355 goes into 53 0 times with a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Take the next digit (2) from the dividend and append it to 53, then repeat: 532 / 355

On to step 3:
If we divide 532 by 355, we get 1 and a remainder of 177.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 355 from 532 and we're left with 177.
Fetch the next digit (7) from the dividend, attach it to 177 and continue: 1777 / 355

Advancing to step 4:
355 can be fit into 1777 5 times, resulting in a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtracting 1775 from 1777 leaves us with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 355

Step 5:
355 goes into 28 0 times with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 150.0
Deduct 0 from 28 and we're left with 28.
Bring next digit (8) of the dividend behind the 28 and repeat the process: 288 / 355

Let's proceed to step 6:
The number 355 fits into 288 0 times, leaving a remainder of 288.
Record the quotient 0 as the next digit in the result. 
Result so far: 1500.0
Subtracting 0 from 288 leaves us with 288.
Grab the next digit (6) from the dividend, add it to 288, then carry on: 2886 / 355

Step 7:
If we divide 2886 by 355, we get 8 and a remainder of 46.
Put 8 as the next digit of the answer. 
Result so far: 15008.0
Subtract 2840 from 2886 to get 46.
Bring next digit (1) of the dividend behind the 46 and repeat the process: 461 / 355

Advancing to step 8:
461 divided by 355 is 1 with a remainder of 106.
The next digit of our result is 1. 
Result so far: 150081.0
If we subtract 355 from 461, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

On to step 9:
When dividing 1060 by 355, we get 2 with a remainder of 350.
The number 2 becomes the next digit in our result. 
Result so far: 150081.2
Subtracting 710 from 1060 leaves us with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 10:
If we divide 3500 by 355, we get 9 and a remainder of 305.
Use 9 as the next digit of our solution. 
Result so far: 150081.29
Subtracting 3195 from 3500 leaves us with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Moving on to step 11:
The number 355 fits into 3050 8 times, leaving a remainder of 210.
The number 8 becomes the next digit in our result. 
Result so far: 150081.298
If we subtract 2840 from 3050, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 12:
When dividing 2100 by 355, we get 5 with a remainder of 325.
The number 5 becomes the next digit in our result. 
Result so far: 150081.2985
The remainder is 325 after subtracting 1775 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

On to step 13:
355 goes into 3250 9 times with a remainder of 55.
The next digit of our result is 9. 
Result so far: 150081.29859
The remainder is 55 after subtracting 3195 from 3250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 14:
550 divided by 355 is 1 with a remainder of 195.
Use 1 as the next digit of our solution. 
Result so far: 150081.298591
Subtract 355 from 550 to get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

On to step 15:
If we divide 1950 by 355, we get 5 and a remainder of 175.
Write down 5 as next digit of the result. 
Result so far: 150081.2985915
Subtracting 1775 from 1950 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Step 16:
355 can be fit into 1750 4 times, resulting in a remainder of 330.
The next digit of our result is 4. 
Result so far: 150081.29859154
The remainder is 330 after subtracting 1420 from 1750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

After the division, we end up with 150081.29859154 and a remainder of 3.3e-07.
