35990645 ÷ 826 
The aim is to understand the frequency of 826 in 35990645.

Step 1:
826 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 826

On to step 2:
35 divided by 826 is 0 with a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Append the next digit (9) from the dividend to 35 and continue with: 359 / 826

On to step 3:
The number 826 fits into 359 0 times, leaving a remainder of 359.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 359 after subtracting 0 from 359.
Bring next digit (9) of the dividend behind the 359 and repeat the process: 3599 / 826

Going ahead to step 4:
3599 divided by 826 is 4 with a remainder of 295.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 3304 from 3599, we get 295.
Fetch the next digit (0) from the dividend, attach it to 295 and continue: 2950 / 826

On to step 5:
When dividing 2950 by 826, we get 3 with a remainder of 472.
Use 3 as the next digit of our solution. 
Result so far: 43.0
The remainder is 472 after subtracting 2478 from 2950.
Bring next digit (6) of the dividend behind the 472 and repeat the process: 4726 / 826

Step 6:
826 can be fit into 4726 5 times, resulting in a remainder of 596.
Put 5 as the next digit of the answer. 
Result so far: 435.0
If we subtract 4130 from 4726, we get 596.
Grab the next digit (4) from the dividend, add it to 596, then carry on: 5964 / 826

Step 7:
When dividing 5964 by 826, we get 7 with a remainder of 182.
The number 7 becomes the next digit in our result. 
Result so far: 4357.0
If we subtract 5782 from 5964, we get 182.
Bring next digit (5) of the dividend behind the 182 and repeat the process: 1825 / 826

Let's proceed to step 8:
When dividing 1825 by 826, we get 2 with a remainder of 173.
Write down 2 as next digit of the result. 
Result so far: 43572.0
If we subtract 1652 from 1825, we get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

On to step 9:
826 goes into 1730 2 times with a remainder of 78.
The next digit of our result is 2. 
Result so far: 43572.2
Subtracting 1652 from 1730 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 10:
The number 826 fits into 780 0 times, leaving a remainder of 780.
Record the quotient 0 as the next digit in the result. 
Result so far: 43572.2
Subtract 0 from 780 to get 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Going ahead to step 11:
826 can be fit into 7800 9 times, resulting in a remainder of 366.
The number 9 becomes the next digit in our result. 
Result so far: 43572.209
The remainder is 366 after subtracting 7434 from 7800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Going ahead to step 12:
3660 divided by 826 is 4 with a remainder of 356.
Record the quotient 4 as the next digit in the result. 
Result so far: 43572.2094
Subtract 3304 from 3660 to get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

On to step 13:
If we divide 3560 by 826, we get 4 and a remainder of 256.
Write down 4 as next digit of the result. 
Result so far: 43572.20944
Subtract 3304 from 3560 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

After the division, we end up with 43572.20944 and a remainder of 0.000256.
