We're dividing 33156906 by 643 
We want to figure out the number of times 33156906 can be divided by 643.

Going ahead to step 1:
When dividing 3 by 643, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 643

Going ahead to step 2:
643 can be fit into 33 0 times, resulting in a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 33 leaves us with 33.
Take the next digit (1) from the dividend and append it to 33, then repeat: 331 / 643

Moving on to step 3:
643 can be fit into 331 0 times, resulting in a remainder of 331.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 331 leaves us with 331.
Append the next digit (5) from the dividend to 331 and continue with: 3315 / 643

Going ahead to step 4:
If we divide 3315 by 643, we get 5 and a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 3215 away from 3315, we end up with 100.
Bring next digit (6) of the dividend behind the 100 and repeat the process: 1006 / 643

Going ahead to step 5:
643 goes into 1006 1 times with a remainder of 363.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
If we take 643 away from 1006, we end up with 363.
Append the next digit (9) from the dividend to 363 and continue with: 3639 / 643

On to step 6:
3639 divided by 643 is 5 with a remainder of 424.
The next digit of our result is 5. 
Result so far: 515.0
If we subtract 3215 from 3639, we get 424.
Include the next digit (0) from the dividend after 424, then repeat: 4240 / 643

Step 7:
643 can be fit into 4240 6 times, resulting in a remainder of 382.
Record the quotient 6 as the next digit in the result. 
Result so far: 5156.0
Subtracting 3858 from 4240 leaves us with 382.
Fetch the next digit (6) from the dividend, attach it to 382 and continue: 3826 / 643

Going ahead to step 8:
643 can be fit into 3826 5 times, resulting in a remainder of 611.
The next digit of our result is 5. 
Result so far: 51565.0
If we subtract 3215 from 3826, we get 611.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6110, and continue the process.

Step 9:
6110 divided by 643 is 9 with a remainder of 323.
Use 9 as the next digit of our solution. 
Result so far: 51565.9
If we subtract 5787 from 6110, we get 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Going ahead to step 10:
When dividing 3230 by 643, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 51565.95
Subtract 3215 from 3230 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 11:
If we divide 150 by 643, we get 0 and a remainder of 150.
The next digit of our result is 0. 
Result so far: 51565.95
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 12:
643 can be fit into 1500 2 times, resulting in a remainder of 214.
Use 2 as the next digit of our solution. 
Result so far: 51565.9502
If we take 1286 away from 1500, we end up with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Going ahead to step 13:
643 goes into 2140 3 times with a remainder of 211.
Use 3 as the next digit of our solution. 
Result so far: 51565.95023
Deduct 1929 from 2140 and we're left with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Going ahead to step 14:
When dividing 2110 by 643, we get 3 with a remainder of 181.
The next digit of our result is 3. 
Result so far: 51565.950233
If we subtract 1929 from 2110, we get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Our division results in 51565.950233 with a remaining 1.81e-05.
