686478 ÷ 93 
The aim is to understand the frequency of 93 in 686478.

Going ahead to step 1:
The number 93 fits into 6 0 times, leaving 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 (8) from the dividend, add it to 6, then carry on: 68 / 93

On to step 2:
The number 93 fits into 68 0 times, leaving a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Append the next digit (6) from the dividend to 68 and continue with: 686 / 93

Step 3:
If we divide 686 by 93, we get 7 and a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 651 from 686 to get 35.
Append the next digit (4) from the dividend to 35 and continue with: 354 / 93

Going ahead to step 4:
93 can be fit into 354 3 times, resulting in a remainder of 75.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
Subtracting 279 from 354 leaves us with 75.
Bring next digit (7) of the dividend behind the 75 and repeat the process: 757 / 93

Going ahead to step 5:
If we divide 757 by 93, we get 8 and a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 738.0
Subtract 744 from 757 to get 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 93

Let's proceed to step 6:
When dividing 138 by 93, we get 1 with a remainder of 45.
The number 1 becomes the next digit in our result. 
Result so far: 7381.0
The remainder is 45 after subtracting 93 from 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 7:
The number 93 fits into 450 4 times, leaving a remainder of 78.
Write down 4 as next digit of the result. 
Result so far: 7381.4
If we take 372 away from 450, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 8:
When dividing 780 by 93, we get 8 with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 7381.48
Subtract 744 from 780 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
93 can be fit into 360 3 times, resulting in a remainder of 81.
The next digit of our result is 3. 
Result so far: 7381.483
Subtracting 279 from 360 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 10:
When dividing 810 by 93, we get 8 with a remainder of 66.
The next digit of our result is 8. 
Result so far: 7381.4838
If we subtract 744 from 810, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 11:
93 goes into 660 7 times with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 7381.48387
Deduct 651 from 660 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 12:
When dividing 90 by 93, we get 0 with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 7381.48387
If we subtract 0 from 90, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 13:
93 goes into 900 9 times with a remainder of 63.
Use 9 as the next digit of our solution. 
Result so far: 7381.4838709
Subtracting 837 from 900 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 14:
If we divide 630 by 93, we get 6 and a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 7381.48387096
Deduct 558 from 630 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The quotient of the division is 7381.48387096, and the remainder is 7.2e-08.
