Let's divide 33435810 by 866
The aim is to understand the frequency of 866 in 33435810.

On to step 1:
The number 866 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 866

Let's proceed to step 2:
If we divide 33 by 866, we get 0 and a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 33, we get 33.
Take the next digit (4) from the dividend and append it to 33, then repeat: 334 / 866

Let's proceed to step 3:
334 divided by 866 is 0 with a remainder of 334.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 334 leaves us with 334.
Fetch the next digit (3) from the dividend, attach it to 334 and continue: 3343 / 866

On to step 4:
866 can be fit into 3343 3 times, resulting in a remainder of 745.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 2598 from 3343 leaves us with 745.
Take the next digit (5) from the dividend and append it to 745, then repeat: 7455 / 866

Let's proceed to step 5:
866 goes into 7455 8 times with a remainder of 527.
Use 8 as the next digit of our solution. 
Result so far: 38.0
If we take 6928 away from 7455, we end up with 527.
Append the next digit (8) from the dividend to 527 and continue with: 5278 / 866

Going ahead to step 6:
866 can be fit into 5278 6 times, resulting in a remainder of 82.
The number 6 becomes the next digit in our result. 
Result so far: 386.0
Subtract 5196 from 5278 to get 82.
Append the next digit (1) from the dividend to 82 and continue with: 821 / 866

On to step 7:
821 divided by 866 is 0 with a remainder of 821.
Put 0 as the next digit of the answer. 
Result so far: 3860.0
If we subtract 0 from 821, we get 821.
Grab the next digit (0) from the dividend, add it to 821, then carry on: 8210 / 866

Let's proceed to step 8:
866 can be fit into 8210 9 times, resulting in a remainder of 416.
The number 9 becomes the next digit in our result. 
Result so far: 38609.0
The remainder is 416 after subtracting 7794 from 8210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 9:
When dividing 4160 by 866, we get 4 with a remainder of 696.
Put 4 as the next digit of the answer. 
Result so far: 38609.4
The remainder is 696 after subtracting 3464 from 4160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Advancing to step 10:
When dividing 6960 by 866, we get 8 with a remainder of 32.
The next digit of our result is 8. 
Result so far: 38609.48
Deduct 6928 from 6960 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 11:
If we divide 320 by 866, we get 0 and a remainder of 320.
The next digit of our result is 0. 
Result so far: 38609.48
Deduct 0 from 320 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 12:
If we divide 3200 by 866, we get 3 and a remainder of 602.
Record the quotient 3 as the next digit in the result. 
Result so far: 38609.4803
Subtract 2598 from 3200 to get 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Going ahead to step 13:
When dividing 6020 by 866, we get 6 with a remainder of 824.
Use 6 as the next digit of our solution. 
Result so far: 38609.48036
If we take 5196 away from 6020, we end up with 824.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8240, and continue the process.

Step 14:
When dividing 8240 by 866, we get 9 with a remainder of 446.
Record the quotient 9 as the next digit in the result. 
Result so far: 38609.480369
If we subtract 7794 from 8240, we get 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Step 15:
866 goes into 4460 5 times with a remainder of 130.
The next digit of our result is 5. 
Result so far: 38609.4803695
If we take 4330 away from 4460, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 16:
1300 divided by 866 is 1 with a remainder of 434.
Write down 1 as next digit of the result. 
Result so far: 38609.48036951
Subtract 866 from 1300 to get 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

After the division, we end up with 38609.48036951 and a remainder of 4.34e-07.
