91749346 divided by 689 
The aim is to understand the frequency of 689 in 91749346.

Going ahead to step 1:
689 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 689

On to step 2:
91 divided by 689 is 0 with a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Take the next digit (7) from the dividend and append it to 91, then repeat: 917 / 689

Step 3:
689 can be fit into 917 1 times, resulting in a remainder of 228.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 689 from 917, we get 228.
Fetch the next digit (4) from the dividend, attach it to 228 and continue: 2284 / 689

Advancing to step 4:
689 goes into 2284 3 times with a remainder of 217.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtract 2067 from 2284 to get 217.
Fetch the next digit (9) from the dividend, attach it to 217 and continue: 2179 / 689

On to step 5:
When dividing 2179 by 689, we get 3 with a remainder of 112.
Write down 3 as next digit of the result. 
Result so far: 133.0
Subtracting 2067 from 2179 leaves us with 112.
Bring next digit (3) of the dividend behind the 112 and repeat the process: 1123 / 689

Let's proceed to step 6:
689 goes into 1123 1 times with a remainder of 434.
Write down 1 as next digit of the result. 
Result so far: 1331.0
If we take 689 away from 1123, we end up with 434.
Include the next digit (4) from the dividend after 434, then repeat: 4344 / 689

Step 7:
If we divide 4344 by 689, we get 6 and a remainder of 210.
Record the quotient 6 as the next digit in the result. 
Result so far: 13316.0
If we subtract 4134 from 4344, we get 210.
Append the next digit (6) from the dividend to 210 and continue with: 2106 / 689

Let's proceed to step 8:
689 goes into 2106 3 times with a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 133163.0
If we subtract 2067 from 2106, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 9:
689 can be fit into 390 0 times, resulting in a remainder of 390.
The next digit of our result is 0. 
Result so far: 133163.0
If we take 0 away from 390, we end up with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 10:
3900 divided by 689 is 5 with a remainder of 455.
Write down 5 as next digit of the result. 
Result so far: 133163.05
Subtracting 3445 from 3900 leaves us with 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Going ahead to step 11:
The number 689 fits into 4550 6 times, leaving a remainder of 416.
Use 6 as the next digit of our solution. 
Result so far: 133163.056
Subtract 4134 from 4550 to get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Advancing to step 12:
If we divide 4160 by 689, we get 6 and a remainder of 26.
Write down 6 as next digit of the result. 
Result so far: 133163.0566
Deduct 4134 from 4160 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The quotient of the division is 133163.0566, and the remainder is 0.00026.
