We're dividing 39497601 by 356 
The aim is to understand the frequency of 356 in 39497601.

Going ahead to step 1:
When dividing 3 by 356, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 356

Advancing to step 2:
If we divide 39 by 356, we get 0 and a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Include the next digit (4) from the dividend after 39, then repeat: 394 / 356

Going ahead to step 3:
356 can be fit into 394 1 times, resulting in a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 356 from 394 and we're left with 38.
Bring next digit (9) of the dividend behind the 38 and repeat the process: 389 / 356

Step 4:
389 divided by 356 is 1 with a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtract 356 from 389 to get 33.
Take the next digit (7) from the dividend and append it to 33, then repeat: 337 / 356

Let's proceed to step 5:
The number 356 fits into 337 0 times, leaving a remainder of 337.
Record the quotient 0 as the next digit in the result. 
Result so far: 110.0
Subtract 0 from 337 to get 337.
Take the next digit (6) from the dividend and append it to 337, then repeat: 3376 / 356

On to step 6:
3376 divided by 356 is 9 with a remainder of 172.
The number 9 becomes the next digit in our result. 
Result so far: 1109.0
Deduct 3204 from 3376 and we're left with 172.
Bring next digit (0) of the dividend behind the 172 and repeat the process: 1720 / 356

Going ahead to step 7:
When dividing 1720 by 356, we get 4 with a remainder of 296.
Write down 4 as next digit of the result. 
Result so far: 11094.0
If we subtract 1424 from 1720, we get 296.
Bring next digit (1) of the dividend behind the 296 and repeat the process: 2961 / 356

Advancing to step 8:
If we divide 2961 by 356, we get 8 and a remainder of 113.
The number 8 becomes the next digit in our result. 
Result so far: 110948.0
Deduct 2848 from 2961 and we're left with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Going ahead to step 9:
1130 divided by 356 is 3 with a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 110948.3
Subtracting 1068 from 1130 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 10:
The number 356 fits into 620 1 times, leaving a remainder of 264.
Record the quotient 1 as the next digit in the result. 
Result so far: 110948.31
If we subtract 356 from 620, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Going ahead to step 11:
2640 divided by 356 is 7 with a remainder of 148.
Record the quotient 7 as the next digit in the result. 
Result so far: 110948.317
Subtracting 2492 from 2640 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Moving on to step 12:
356 can be fit into 1480 4 times, resulting in a remainder of 56.
The next digit of our result is 4. 
Result so far: 110948.3174
If we take 1424 away from 1480, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 13:
356 goes into 560 1 times with a remainder of 204.
Record the quotient 1 as the next digit in the result. 
Result so far: 110948.31741
Deduct 356 from 560 and we're left with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Let's proceed to step 14:
356 goes into 2040 5 times with a remainder of 260.
Use 5 as the next digit of our solution. 
Result so far: 110948.317415
If we take 1780 away from 2040, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 15:
When dividing 2600 by 356, we get 7 with a remainder of 108.
Use 7 as the next digit of our solution. 
Result so far: 110948.3174157
If we subtract 2492 from 2600, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 16:
1080 divided by 356 is 3 with a remainder of 12.
The next digit of our result is 3. 
Result so far: 110948.31741573
The remainder is 12 after subtracting 1068 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 110948.31741573 with a remainder of 1.2e-08.
