Let's divide 70208001 by 688
The aim is to understand the frequency of 688 in 70208001.

Step 1:
688 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 688

On to step 2:
688 goes into 70 0 times with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Take the next digit (2) from the dividend and append it to 70, then repeat: 702 / 688

On to step 3:
The number 688 fits into 702 1 times, leaving a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 688 from 702 and we're left with 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 688

Advancing to step 4:
The number 688 fits into 140 0 times, leaving a remainder of 140.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 140 leaves us with 140.
Take the next digit (8) from the dividend and append it to 140, then repeat: 1408 / 688

Step 5:
688 can be fit into 1408 2 times, resulting in a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 102.0
If we subtract 1376 from 1408, we get 32.
Grab the next digit (0) from the dividend, add it to 32, then carry on: 320 / 688

On to step 6:
688 goes into 320 0 times with a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 1020.0
If we subtract 0 from 320, we get 320.
Bring next digit (0) of the dividend behind the 320 and repeat the process: 3200 / 688

On to step 7:
When dividing 3200 by 688, we get 4 with a remainder of 448.
The next digit of our result is 4. 
Result so far: 10204.0
The remainder is 448 after subtracting 2752 from 3200.
Take the next digit (1) from the dividend and append it to 448, then repeat: 4481 / 688

Moving on to step 8:
When dividing 4481 by 688, we get 6 with a remainder of 353.
The number 6 becomes the next digit in our result. 
Result so far: 102046.0
If we subtract 4128 from 4481, we get 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Step 9:
3530 divided by 688 is 5 with a remainder of 90.
Record the quotient 5 as the next digit in the result. 
Result so far: 102046.5
If we take 3440 away from 3530, 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.

Let's proceed to step 10:
The number 688 fits into 900 1 times, leaving a remainder of 212.
Use 1 as the next digit of our solution. 
Result so far: 102046.51
Subtracting 688 from 900 leaves us with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Advancing to step 11:
If we divide 2120 by 688, we get 3 and a remainder of 56.
Record the quotient 3 as the next digit in the result. 
Result so far: 102046.513
Subtracting 2064 from 2120 leaves us 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 12:
If we divide 560 by 688, we get 0 and a remainder of 560.
The number 0 becomes the next digit in our result. 
Result so far: 102046.513
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.

Step 13:
688 can be fit into 5600 8 times, resulting in a remainder of 96.
The next digit of our result is 8. 
Result so far: 102046.51308
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.
Write down 1 as next digit of the result. 
Result so far: 102046.513081
Deduct 688 from 960 and we're left 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.

Going ahead to step 15:
688 goes into 2720 3 times with a remainder of 656.
Write down 3 as next digit of the result. 
Result so far: 102046.5130813
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.

Going ahead to step 16:
688 goes into 6560 9 times with a remainder of 368.
Record the quotient 9 as the next digit in the result. 
Result so far: 102046.51308139
If we take 6192 away from 6560, we end up 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.

In conclusion, the division gives 102046.51308139 with a balance of 3.68e-07.
