Let's divide 63428105 by 688
The aim is to understand the frequency of 688 in 63428105.

Going ahead to step 1:
If we divide 6 by 688, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 688

Let's proceed to step 2:
688 can be fit into 63 0 times, resulting in a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Fetch the next digit (4) from the dividend, attach it to 63 and continue: 634 / 688

Moving on to step 3:
634 divided by 688 is 0 with a remainder of 634.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 634 after subtracting 0 from 634.
Fetch the next digit (2) from the dividend, attach it to 634 and continue: 6342 / 688

On to step 4:
688 goes into 6342 9 times with a remainder of 150.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 150 after subtracting 6192 from 6342.
Grab the next digit (8) from the dividend, add it to 150, then carry on: 1508 / 688

Moving on to step 5:
The number 688 fits into 1508 2 times, leaving a remainder of 132.
The number 2 becomes the next digit in our result. 
Result so far: 92.0
Subtracting 1376 from 1508 leaves us with 132.
Append the next digit (1) from the dividend to 132 and continue with: 1321 / 688

On to step 6:
688 can be fit into 1321 1 times, resulting in a remainder of 633.
The number 1 becomes the next digit in our result. 
Result so far: 921.0
Subtract 688 from 1321 to get 633.
Grab the next digit (0) from the dividend, add it to 633, then carry on: 6330 / 688

Step 7:
688 can be fit into 6330 9 times, resulting in a remainder of 138.
Write down 9 as next digit of the result. 
Result so far: 9219.0
Subtracting 6192 from 6330 leaves us with 138.
Take the next digit (5) from the dividend and append it to 138, then repeat: 1385 / 688

Step 8:
1385 divided by 688 is 2 with a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 92192.0
If we take 1376 away from 1385, we end up 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.

On to step 9:
90 divided by 688 is 0 with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 92192.0
If we take 0 away from 90, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 10:
If we divide 900 by 688, we get 1 and a remainder of 212.
The next digit of our result is 1. 
Result so far: 92192.01
The remainder is 212 after subtracting 688 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Let's proceed to step 11:
If we divide 2120 by 688, we get 3 and a remainder of 56.
The number 3 becomes the next digit in our result. 
Result so far: 92192.013
Deduct 2064 from 2120 and we're left 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.

Advancing to step 12:
560 divided by 688 is 0 with a remainder of 560.
The next digit of our result is 0. 
Result so far: 92192.013
Deduct 0 from 560 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Advancing to step 13:
688 can be fit into 5600 8 times, resulting in a remainder of 96.
The number 8 becomes the next digit in our result. 
Result so far: 92192.01308
If we subtract 5504 from 5600, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 14:
688 goes into 960 1 times with a remainder of 272.
Use 1 as the next digit of our solution. 
Result so far: 92192.013081
Subtracting 688 from 960 leaves us with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

On to step 15:
The number 688 fits into 2720 3 times, leaving a remainder of 656.
The next digit of our result is 3. 
Result so far: 92192.0130813
If we take 2064 away from 2720, we end up with 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

On to step 16:
The number 688 fits into 6560 9 times, leaving a remainder of 368.
Write down 9 as next digit of the result. 
Result so far: 92192.01308139
Deduct 6192 from 6560 and we're left with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

The final result is 92192.01308139 with a remainder of 3.68e-07.
