93623921 ÷ 688 
The aim is to understand the frequency of 688 in 93623921.

Going ahead to step 1:
688 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 688

Let's proceed to step 2:
688 can be fit into 93 0 times, resulting in a remainder of 93.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 93 after subtracting 0 from 93.
Append the next digit (6) from the dividend to 93 and continue with: 936 / 688

Going ahead to step 3:
If we divide 936 by 688, we get 1 and a remainder of 248.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 248 after subtracting 688 from 936.
Grab the next digit (2) from the dividend, add it to 248, then carry on: 2482 / 688

Step 4:
The number 688 fits into 2482 3 times, leaving a remainder of 418.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Deduct 2064 from 2482 and we're left with 418.
Take the next digit (3) from the dividend and append it to 418, then repeat: 4183 / 688

On to step 5:
688 goes into 4183 6 times with a remainder of 55.
Put 6 as the next digit of the answer. 
Result so far: 136.0
The remainder is 55 after subtracting 4128 from 4183.
Include the next digit (9) from the dividend after 55, then repeat: 559 / 688

Let's proceed to step 6:
559 divided by 688 is 0 with a remainder of 559.
Record the quotient 0 as the next digit in the result. 
Result so far: 1360.0
The remainder is 559 after subtracting 0 from 559.
Append the next digit (2) from the dividend to 559 and continue with: 5592 / 688

Let's proceed to step 7:
5592 divided by 688 is 8 with a remainder of 88.
The number 8 becomes the next digit in our result. 
Result so far: 13608.0
If we subtract 5504 from 5592, we get 88.
Fetch the next digit (1) from the dividend, attach it to 88 and continue: 881 / 688

Moving on to step 8:
688 can be fit into 881 1 times, resulting in a remainder of 193.
The next digit of our result is 1. 
Result so far: 136081.0
If we subtract 688 from 881, we get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Step 9:
688 can be fit into 1930 2 times, resulting in a remainder of 554.
The next digit of our result is 2. 
Result so far: 136081.2
Subtracting 1376 from 1930 leaves us with 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Going ahead to step 10:
688 can be fit into 5540 8 times, resulting in a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 136081.28
Subtracting 5504 from 5540 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 11:
When dividing 360 by 688, we get 0 with a remainder of 360.
The number 0 becomes the next digit in our result. 
Result so far: 136081.28
If we subtract 0 from 360, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 12:
688 goes into 3600 5 times with a remainder of 160.
Write down 5 as next digit of the result. 
Result so far: 136081.2805
If we take 3440 away from 3600, we end up 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.

Step 13:
688 can be fit into 1600 2 times, resulting in a remainder of 224.
Use 2 as the next digit of our solution. 
Result so far: 136081.28052
Deduct 1376 from 1600 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Going ahead to step 14:
2240 divided by 688 is 3 with a remainder of 176.
The next digit of our result is 3. 
Result so far: 136081.280523
Subtract 2064 from 2240 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 15:
If we divide 1760 by 688, we get 2 and a remainder of 384.
Record the quotient 2 as the next digit in the result. 
Result so far: 136081.2805232
If we take 1376 away from 1760, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 16:
688 goes into 3840 5 times with a remainder of 400.
The next digit of our result is 5. 
Result so far: 136081.28052325
If we take 3440 away from 3840, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The quotient of the division is 136081.28052325, and the remainder is 4e-07.
