Let's divide 90691653 by 607
The aim is to understand the frequency of 607 in 90691653.

On to step 1:
9 divided by 607 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 607

Advancing to step 2:
90 divided by 607 is 0 with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Include the next digit (6) from the dividend after 90, then repeat: 906 / 607

Let's proceed to step 3:
906 divided by 607 is 1 with a remainder of 299.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 607 from 906 to get 299.
Include the next digit (9) from the dividend after 299, then repeat: 2999 / 607

Going ahead to step 4:
607 can be fit into 2999 4 times, resulting in a remainder of 571.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
The remainder is 571 after subtracting 2428 from 2999.
Fetch the next digit (1) from the dividend, attach it to 571 and continue: 5711 / 607

Advancing to step 5:
607 goes into 5711 9 times with a remainder of 248.
Use 9 as the next digit of our solution. 
Result so far: 149.0
The remainder is 248 after subtracting 5463 from 5711.
Include the next digit (6) from the dividend after 248, then repeat: 2486 / 607

Going ahead to step 6:
The number 607 fits into 2486 4 times, leaving a remainder of 58.
Use 4 as the next digit of our solution. 
Result so far: 1494.0
If we take 2428 away from 2486, we end up with 58.
Append the next digit (5) from the dividend to 58 and continue with: 585 / 607

On to step 7:
If we divide 585 by 607, we get 0 and a remainder of 585.
The next digit of our result is 0. 
Result so far: 14940.0
Subtract 0 from 585 to get 585.
Bring next digit (3) of the dividend behind the 585 and repeat the process: 5853 / 607

Step 8:
607 goes into 5853 9 times with a remainder of 390.
The number 9 becomes the next digit in our result. 
Result so far: 149409.0
Subtract 5463 from 5853 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Let's proceed to step 9:
The number 607 fits into 3900 6 times, leaving a remainder of 258.
Put 6 as the next digit of the answer. 
Result so far: 149409.6
Subtracting 3642 from 3900 leaves us with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Going ahead to step 10:
The number 607 fits into 2580 4 times, leaving a remainder of 152.
Put 4 as the next digit of the answer. 
Result so far: 149409.64
Subtract 2428 from 2580 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 11:
607 can be fit into 1520 2 times, resulting in a remainder of 306.
Use 2 as the next digit of our solution. 
Result so far: 149409.642
Subtract 1214 from 1520 to get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Advancing to step 12:
607 can be fit into 3060 5 times, resulting in a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 149409.6425
If we subtract 3035 from 3060, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 13:
When dividing 250 by 607, we get 0 with a remainder of 250.
Use 0 as the next digit of our solution. 
Result so far: 149409.6425
Deduct 0 from 250 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 14:
If we divide 2500 by 607, we get 4 and a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 149409.642504
Subtracting 2428 from 2500 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 15:
The number 607 fits into 720 1 times, leaving a remainder of 113.
The next digit of our result is 1. 
Result so far: 149409.6425041
The remainder is 113 after subtracting 607 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Going ahead to step 16:
607 goes into 1130 1 times with a remainder of 523.
The next digit of our result is 1. 
Result so far: 149409.64250411
If we take 607 away from 1130, we end up with 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

The final result is 149409.64250411 with a remainder of 5.23e-07.
