We're dividing 35940644 by 891 
The aim is to understand the frequency of 891 in 35940644.

Step 1:
When dividing 3 by 891, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 891

Let's proceed to step 2:
35 divided by 891 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.
Fetch the next digit (9) from the dividend, attach it to 35 and continue: 359 / 891

Advancing to step 3:
891 can be fit into 359 0 times, resulting in a remainder of 359.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 359, we end up with 359.
Include the next digit (4) from the dividend after 359, then repeat: 3594 / 891

On to step 4:
The number 891 fits into 3594 4 times, leaving a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 3564 from 3594 to get 30.
Append the next digit (0) from the dividend to 30 and continue with: 300 / 891

Moving on to step 5:
891 goes into 300 0 times with a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 40.0
Subtracting 0 from 300 leaves us with 300.
Append the next digit (6) from the dividend to 300 and continue with: 3006 / 891

On to step 6:
If we divide 3006 by 891, we get 3 and a remainder of 333.
Write down 3 as next digit of the result. 
Result so far: 403.0
The remainder is 333 after subtracting 2673 from 3006.
Append the next digit (4) from the dividend to 333 and continue with: 3334 / 891

Moving on to step 7:
When dividing 3334 by 891, we get 3 with a remainder of 661.
Record the quotient 3 as the next digit in the result. 
Result so far: 4033.0
Deduct 2673 from 3334 and we're left with 661.
Take the next digit (4) from the dividend and append it to 661, then repeat: 6614 / 891

Advancing to step 8:
6614 divided by 891 is 7 with a remainder of 377.
Record the quotient 7 as the next digit in the result. 
Result so far: 40337.0
Subtract 6237 from 6614 to get 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

On to step 9:
If we divide 3770 by 891, we get 4 and a remainder of 206.
The next digit of our result is 4. 
Result so far: 40337.4
If we take 3564 away from 3770, we end up with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

On to step 10:
When dividing 2060 by 891, we get 2 with a remainder of 278.
The next digit of our result is 2. 
Result so far: 40337.42
The remainder is 278 after subtracting 1782 from 2060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Moving on to step 11:
If we divide 2780 by 891, we get 3 and a remainder of 107.
Write down 3 as next digit of the result. 
Result so far: 40337.423
If we subtract 2673 from 2780, we get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Advancing to step 12:
When dividing 1070 by 891, we get 1 with a remainder of 179.
Put 1 as the next digit of the answer. 
Result so far: 40337.4231
The remainder is 179 after subtracting 891 from 1070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Advancing to step 13:
The number 891 fits into 1790 2 times, leaving a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 40337.42312
Deduct 1782 from 1790 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 14:
80 divided by 891 is 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 40337.42312
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 15:
891 can be fit into 800 0 times, resulting in a remainder of 800.
The number 0 becomes the next digit in our result. 
Result so far: 40337.42312
Subtract 0 from 800 to get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

The final outcome is 40337.42312, with a leftover of 8e-06.
