We're dividing 30823703 by 645 
Let's see how many times 645 fits into 30823703.

Advancing to step 1:
3 divided by 645 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 645

Let's proceed to step 2:
The number 645 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Fetch the next digit (8) from the dividend, attach it to 30 and continue: 308 / 645

Moving on to step 3:
645 can be fit into 308 0 times, resulting in a remainder of 308.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 308, we get 308.
Grab the next digit (2) from the dividend, add it to 308, then carry on: 3082 / 645

Advancing to step 4:
3082 divided by 645 is 4 with a remainder of 502.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 2580 away from 3082, we end up with 502.
Bring next digit (3) of the dividend behind the 502 and repeat the process: 5023 / 645

Moving on to step 5:
645 can be fit into 5023 7 times, resulting in a remainder of 508.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
If we subtract 4515 from 5023, we get 508.
Fetch the next digit (7) from the dividend, attach it to 508 and continue: 5087 / 645

Going ahead to step 6:
645 goes into 5087 7 times with a remainder of 572.
The number 7 becomes the next digit in our result. 
Result so far: 477.0
If we subtract 4515 from 5087, we get 572.
Bring next digit (0) of the dividend behind the 572 and repeat the process: 5720 / 645

Let's proceed to step 7:
The number 645 fits into 5720 8 times, leaving a remainder of 560.
The number 8 becomes the next digit in our result. 
Result so far: 4778.0
If we take 5160 away from 5720, we end up with 560.
Grab the next digit (3) from the dividend, add it to 560, then carry on: 5603 / 645

Advancing to step 8:
5603 divided by 645 is 8 with a remainder of 443.
Use 8 as the next digit of our solution. 
Result so far: 47788.0
Subtracting 5160 from 5603 leaves us with 443.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

Let's proceed to step 9:
645 can be fit into 4430 6 times, resulting in a remainder of 560.
Use 6 as the next digit of our solution. 
Result so far: 47788.6
Subtracting 3870 from 4430 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Advancing to step 10:
The number 645 fits into 5600 8 times, leaving a remainder of 440.
Record the quotient 8 as the next digit in the result. 
Result so far: 47788.68
Deduct 5160 from 5600 and we're left 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.

On to step 11:
If we divide 4400 by 645, we get 6 and a remainder of 530.
Use 6 as the next digit of our solution. 
Result so far: 47788.686
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 12:
If we divide 5300 by 645, we get 8 and a remainder of 140.
The number 8 becomes the next digit in our result. 
Result so far: 47788.6868
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.

Let's proceed to step 13:
645 can be fit into 1400 2 times, resulting in a remainder of 110.
Use 2 as the next digit of our solution. 
Result so far: 47788.68682
If we take 1290 away from 1400, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 14:
1100 divided by 645 is 1 with a remainder of 455.
Record the quotient 1 as the next digit in the result. 
Result so far: 47788.686821
The remainder is 455 after subtracting 645 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Moving on to step 15:
If we divide 4550 by 645, we get 7 and a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 47788.6868217
If we take 4515 away from 4550, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 16:
645 goes into 350 0 times with a remainder of 350.
Put 0 as the next digit of the answer. 
Result so far: 47788.6868217
If we take 0 away from 350, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

After the division, we end up with 47788.6868217 and a remainder of 3.5e-07.
