98720606 divided by 738 
The aim is to understand the frequency of 738 in 98720606.

Advancing to step 1:
738 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 738

Moving on to step 2:
98 divided by 738 is 0 with a remainder of 98.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 98 leaves us with 98.
Append the next digit (7) from the dividend to 98 and continue with: 987 / 738

On to step 3:
987 divided by 738 is 1 with a remainder of 249.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 738 from 987 leaves us with 249.
Bring next digit (2) of the dividend behind the 249 and repeat the process: 2492 / 738

Going ahead to step 4:
The number 738 fits into 2492 3 times, leaving a remainder of 278.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 2214 away from 2492, we end up with 278.
Fetch the next digit (0) from the dividend, attach it to 278 and continue: 2780 / 738

Going ahead to step 5:
738 goes into 2780 3 times with a remainder of 566.
The next digit of our result is 3. 
Result so far: 133.0
Deduct 2214 from 2780 and we're left with 566.
Append the next digit (6) from the dividend to 566 and continue with: 5666 / 738

Step 6:
If we divide 5666 by 738, we get 7 and a remainder of 500.
The number 7 becomes the next digit in our result. 
Result so far: 1337.0
If we take 5166 away from 5666, we end up with 500.
Append the next digit (0) from the dividend to 500 and continue with: 5000 / 738

Advancing to step 7:
5000 divided by 738 is 6 with a remainder of 572.
The next digit of our result is 6. 
Result so far: 13376.0
Subtract 4428 from 5000 to get 572.
Fetch the next digit (6) from the dividend, attach it to 572 and continue: 5726 / 738

On to step 8:
When dividing 5726 by 738, we get 7 with a remainder of 560.
The number 7 becomes the next digit in our result. 
Result so far: 133767.0
Subtract 5166 from 5726 to get 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 9:
5600 divided by 738 is 7 with a remainder of 434.
Use 7 as the next digit of our solution. 
Result so far: 133767.7
The remainder is 434 after subtracting 5166 from 5600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Step 10:
When dividing 4340 by 738, we get 5 with a remainder of 650.
Put 5 as the next digit of the answer. 
Result so far: 133767.75
Subtracting 3690 from 4340 leaves us with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Moving on to step 11:
The number 738 fits into 6500 8 times, leaving a remainder of 596.
Use 8 as the next digit of our solution. 
Result so far: 133767.758
Subtract 5904 from 6500 to get 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Let's proceed to step 12:
738 goes into 5960 8 times with a remainder of 56.
The next digit of our result is 8. 
Result so far: 133767.7588
Subtracting 5904 from 5960 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.

The quotient of the division is 133767.7588, and the remainder is 0.00056.
