We're dividing 76618564 by 355 
The aim is to understand the frequency of 355 in 76618564.

Step 1:
If we divide 7 by 355, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 355

Step 2:
76 divided by 355 is 0 with a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 76 after subtracting 0 from 76.
Grab the next digit (6) from the dividend, add it to 76, then carry on: 766 / 355

On to step 3:
When dividing 766 by 355, we get 2 with a remainder of 56.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 56 after subtracting 710 from 766.
Grab the next digit (1) from the dividend, add it to 56, then carry on: 561 / 355

Advancing to step 4:
When dividing 561 by 355, we get 1 with a remainder of 206.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtracting 355 from 561 leaves us with 206.
Bring next digit (8) of the dividend behind the 206 and repeat the process: 2068 / 355

Step 5:
The number 355 fits into 2068 5 times, leaving a remainder of 293.
Record the quotient 5 as the next digit in the result. 
Result so far: 215.0
Subtract 1775 from 2068 to get 293.
Bring next digit (5) of the dividend behind the 293 and repeat the process: 2935 / 355

Step 6:
If we divide 2935 by 355, we get 8 and a remainder of 95.
Write down 8 as next digit of the result. 
Result so far: 2158.0
If we take 2840 away from 2935, we end up with 95.
Take the next digit (6) from the dividend and append it to 95, then repeat: 956 / 355

Advancing to step 7:
355 goes into 956 2 times with a remainder of 246.
Write down 2 as next digit of the result. 
Result so far: 21582.0
Deduct 710 from 956 and we're left with 246.
Fetch the next digit (4) from the dividend, attach it to 246 and continue: 2464 / 355

On to step 8:
355 can be fit into 2464 6 times, resulting in a remainder of 334.
The next digit of our result is 6. 
Result so far: 215826.0
Subtracting 2130 from 2464 leaves us with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Advancing to step 9:
If we divide 3340 by 355, we get 9 and a remainder of 145.
Write down 9 as next digit of the result. 
Result so far: 215826.9
If we take 3195 away from 3340, we end up with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Going ahead to step 10:
If we divide 1450 by 355, we get 4 and a remainder of 30.
Use 4 as the next digit of our solution. 
Result so far: 215826.94
Subtract 1420 from 1450 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
If we divide 300 by 355, we get 0 and a remainder of 300.
The next digit of our result is 0. 
Result so far: 215826.94
If we take 0 away from 300, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 12:
355 can be fit into 3000 8 times, resulting in a remainder of 160.
Put 8 as the next digit of the answer. 
Result so far: 215826.9408
The remainder is 160 after subtracting 2840 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 13:
355 goes into 1600 4 times with a remainder of 180.
Use 4 as the next digit of our solution. 
Result so far: 215826.94084
Subtract 1420 from 1600 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 14:
1800 divided by 355 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 215826.940845
Subtracting 1775 from 1800 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 15:
355 can be fit into 250 0 times, resulting in a remainder of 250.
The next digit of our result is 0. 
Result so far: 215826.940845
Subtracting 0 from 250 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 16:
2500 divided by 355 is 7 with a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 215826.94084507
If we take 2485 away from 2500, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 215826.94084507 with a remaining 1.5e-08.
