We're dividing 673938 by 88 
The aim is to understand the frequency of 88 in 673938.

Going ahead to step 1:
When dividing 6 by 88, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 88

On to step 2:
88 can be fit into 67 0 times, resulting in a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 67 and we're left with 67.
Fetch the next digit (3) from the dividend, attach it to 67 and continue: 673 / 88

Let's proceed to step 3:
When dividing 673 by 88, we get 7 with a remainder of 57.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 616 away from 673, we end up with 57.
Include the next digit (9) from the dividend after 57, then repeat: 579 / 88

On to step 4:
579 divided by 88 is 6 with a remainder of 51.
Use 6 as the next digit of our solution. 
Result so far: 76.0
If we take 528 away from 579, we end up with 51.
Append the next digit (3) from the dividend to 51 and continue with: 513 / 88

Let's proceed to step 5:
The number 88 fits into 513 5 times, leaving a remainder of 73.
Use 5 as the next digit of our solution. 
Result so far: 765.0
Subtract 440 from 513 to get 73.
Bring next digit (8) of the dividend behind the 73 and repeat the process: 738 / 88

Step 6:
88 can be fit into 738 8 times, resulting in a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 7658.0
If we take 704 away from 738, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 7:
88 can be fit into 340 3 times, resulting in a remainder of 76.
Put 3 as the next digit of the answer. 
Result so far: 7658.3
The remainder is 76 after subtracting 264 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 8:
The number 88 fits into 760 8 times, leaving a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 7658.38
If we take 704 away from 760, we end up 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 9:
If we divide 560 by 88, we get 6 and a remainder of 32.
The next digit of our result is 6. 
Result so far: 7658.386
The remainder is 32 after subtracting 528 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 10:
320 divided by 88 is 3 with a remainder of 56.
The next digit of our result is 3. 
Result so far: 7658.3863
The remainder is 56 after subtracting 264 from 320.
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 11:
The number 88 fits into 560 6 times, leaving a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 7658.38636
Deduct 528 from 560 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 12:
If we divide 320 by 88, we get 3 and a remainder of 56.
Use 3 as the next digit of our solution. 
Result so far: 7658.386363
Deduct 264 from 320 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.

Going ahead to step 13:
When dividing 560 by 88, we get 6 with a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 7658.3863636
Subtract 528 from 560 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 14:
88 goes into 320 3 times with a remainder of 56.
Put 3 as the next digit of the answer. 
Result so far: 7658.38636363
The remainder is 56 after subtracting 264 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final outcome is 7658.38636363, with a leftover of 5.6e-08.
