33202017 divided by 644 
We want to divide 33202017 by 644.

On to step 1:
If we divide 3 by 644, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 644

Step 2:
644 can be fit into 33 0 times, resulting in a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 33 and we're left with 33.
Bring next digit (2) of the dividend behind the 33 and repeat the process: 332 / 644

Going ahead to step 3:
When dividing 332 by 644, we get 0 with a remainder of 332.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 332, we get 332.
Grab the next digit (0) from the dividend, add it to 332, then carry on: 3320 / 644

Advancing to step 4:
If we divide 3320 by 644, we get 5 and a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 3220 from 3320 to get 100.
Take the next digit (2) from the dividend and append it to 100, then repeat: 1002 / 644

Advancing to step 5:
1002 divided by 644 is 1 with a remainder of 358.
Put 1 as the next digit of the answer. 
Result so far: 51.0
Deduct 644 from 1002 and we're left with 358.
Include the next digit (0) from the dividend after 358, then repeat: 3580 / 644

Moving on to step 6:
If we divide 3580 by 644, we get 5 and a remainder of 360.
Write down 5 as next digit of the result. 
Result so far: 515.0
If we take 3220 away from 3580, we end up with 360.
Bring next digit (1) of the dividend behind the 360 and repeat the process: 3601 / 644

Step 7:
When dividing 3601 by 644, we get 5 with a remainder of 381.
Write down 5 as next digit of the result. 
Result so far: 5155.0
The remainder is 381 after subtracting 3220 from 3601.
Fetch the next digit (7) from the dividend, attach it to 381 and continue: 3817 / 644

Advancing to step 8:
When dividing 3817 by 644, we get 5 with a remainder of 597.
The number 5 becomes the next digit in our result. 
Result so far: 51555.0
Subtract 3220 from 3817 to get 597.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5970, and continue the process.

Step 9:
The number 644 fits into 5970 9 times, leaving a remainder of 174.
Record the quotient 9 as the next digit in the result. 
Result so far: 51555.9
Subtract 5796 from 5970 to get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Step 10:
644 goes into 1740 2 times with a remainder of 452.
Use 2 as the next digit of our solution. 
Result so far: 51555.92
Subtracting 1288 from 1740 leaves us with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

On to step 11:
4520 divided by 644 is 7 with a remainder of 12.
The next digit of our result is 7. 
Result so far: 51555.927
The remainder is 12 after subtracting 4508 from 4520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 12:
120 divided by 644 is 0 with a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 51555.927
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 13:
644 can be fit into 1200 1 times, resulting in a remainder of 556.
Write down 1 as next digit of the result. 
Result so far: 51555.92701
If we subtract 644 from 1200, we get 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

On to step 14:
644 can be fit into 5560 8 times, resulting in a remainder of 408.
Use 8 as the next digit of our solution. 
Result so far: 51555.927018
Deduct 5152 from 5560 and we're left with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Going ahead to step 15:
644 goes into 4080 6 times with a remainder of 216.
Put 6 as the next digit of the answer. 
Result so far: 51555.9270186
Deduct 3864 from 4080 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 16:
If we divide 2160 by 644, we get 3 and a remainder of 228.
Record the quotient 3 as the next digit in the result. 
Result so far: 51555.92701863
If we take 1932 away from 2160, we end up with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

After the division, we end up with 51555.92701863 and a remainder of 2.28e-07.
