We look at the division of 60668685 by 356 
The aim is to understand the frequency of 356 in 60668685.

Moving on to step 1:
If we divide 6 by 356, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 356

Step 2:
356 can be fit into 60 0 times, resulting in a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 60 to get 60.
Bring next digit (6) of the dividend behind the 60 and repeat the process: 606 / 356

Step 3:
356 goes into 606 1 times with a remainder of 250.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 356 away from 606, we end up with 250.
Include the next digit (6) from the dividend after 250, then repeat: 2506 / 356

Moving on to step 4:
When dividing 2506 by 356, we get 7 with a remainder of 14.
The next digit of our result is 7. 
Result so far: 17.0
Deduct 2492 from 2506 and we're left with 14.
Grab the next digit (8) from the dividend, add it to 14, then carry on: 148 / 356

Advancing to step 5:
356 can be fit into 148 0 times, resulting in a remainder of 148.
Record the quotient 0 as the next digit in the result. 
Result so far: 170.0
Deduct 0 from 148 and we're left with 148.
Append the next digit (6) from the dividend to 148 and continue with: 1486 / 356

Let's proceed to step 6:
When dividing 1486 by 356, we get 4 with a remainder of 62.
Put 4 as the next digit of the answer. 
Result so far: 1704.0
Subtracting 1424 from 1486 leaves us with 62.
Bring next digit (8) of the dividend behind the 62 and repeat the process: 628 / 356

Going ahead to step 7:
The number 356 fits into 628 1 times, leaving a remainder of 272.
The number 1 becomes the next digit in our result. 
Result so far: 17041.0
The remainder is 272 after subtracting 356 from 628.
Append the next digit (5) from the dividend to 272 and continue with: 2725 / 356

On to step 8:
356 goes into 2725 7 times with a remainder of 233.
The next digit of our result is 7. 
Result so far: 170417.0
If we take 2492 away from 2725, we end up with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Let's proceed to step 9:
When dividing 2330 by 356, we get 6 with a remainder of 194.
Use 6 as the next digit of our solution. 
Result so far: 170417.6
Deduct 2136 from 2330 and we're left with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

On to step 10:
356 goes into 1940 5 times with a remainder of 160.
Put 5 as the next digit of the answer. 
Result so far: 170417.65
Deduct 1780 from 1940 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 11:
356 can be fit into 1600 4 times, resulting in a remainder of 176.
The next digit of our result is 4. 
Result so far: 170417.654
The remainder is 176 after subtracting 1424 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Going ahead to step 12:
When dividing 1760 by 356, we get 4 with a remainder of 336.
Record the quotient 4 as the next digit in the result. 
Result so far: 170417.6544
If we take 1424 away from 1760, we end up with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

The final outcome is 170417.6544, with a leftover of 0.00336.
