We're dividing 31832768 by 645 
We want to divide 31832768 by 645.

Step 1:
645 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.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 645

Advancing to step 2:
The number 645 fits into 31 0 times, leaving a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Fetch the next digit (8) from the dividend, attach it to 31 and continue: 318 / 645

Going ahead to step 3:
645 goes into 318 0 times with a remainder of 318.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 318 after subtracting 0 from 318.
Append the next digit (3) from the dividend to 318 and continue with: 3183 / 645

On to step 4:
645 can be fit into 3183 4 times, resulting in a remainder of 603.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 2580 from 3183 and we're left with 603.
Take the next digit (2) from the dividend and append it to 603, then repeat: 6032 / 645

Going ahead to step 5:
The number 645 fits into 6032 9 times, leaving a remainder of 227.
Write down 9 as next digit of the result. 
Result so far: 49.0
Subtracting 5805 from 6032 leaves us with 227.
Append the next digit (7) from the dividend to 227 and continue with: 2277 / 645

On to step 6:
645 goes into 2277 3 times with a remainder of 342.
The number 3 becomes the next digit in our result. 
Result so far: 493.0
Subtracting 1935 from 2277 leaves us with 342.
Append the next digit (6) from the dividend to 342 and continue with: 3426 / 645

Moving on to step 7:
645 goes into 3426 5 times with a remainder of 201.
Put 5 as the next digit of the answer. 
Result so far: 4935.0
Subtracting 3225 from 3426 leaves us with 201.
Include the next digit (8) from the dividend after 201, then repeat: 2018 / 645

On to step 8:
If we divide 2018 by 645, we get 3 and a remainder of 83.
Put 3 as the next digit of the answer. 
Result so far: 49353.0
If we take 1935 away from 2018, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 9:
830 divided by 645 is 1 with a remainder of 185.
Put 1 as the next digit of the answer. 
Result so far: 49353.1
If we take 645 away from 830, we end up with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 10:
If we divide 1850 by 645, we get 2 and a remainder of 560.
The next digit of our result is 2. 
Result so far: 49353.12
If we subtract 1290 from 1850, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 11:
645 can be fit into 5600 8 times, resulting in a remainder of 440.
Use 8 as the next digit of our solution. 
Result so far: 49353.128
If we take 5160 away from 5600, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 12:
645 goes into 4400 6 times with a remainder of 530.
The next digit of our result is 6. 
Result so far: 49353.1286
Subtract 3870 from 4400 to get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

On to step 13:
645 can be fit into 5300 8 times, resulting in a remainder of 140.
Record the quotient 8 as the next digit in the result. 
Result so far: 49353.12868
The remainder is 140 after subtracting 5160 from 5300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 14:
If we divide 1400 by 645, we get 2 and a remainder of 110.
Record the quotient 2 as the next digit in the result. 
Result so far: 49353.128682
Subtract 1290 from 1400 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 15:
1100 divided by 645 is 1 with a remainder of 455.
Use 1 as the next digit of our solution. 
Result so far: 49353.1286821
Subtracting 645 from 1100 leaves us with 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Going ahead to step 16:
The number 645 fits into 4550 7 times, leaving a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 49353.12868217
Subtract 4515 from 4550 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 49353.12868217, with a leftover of 3.5e-08.
