Let's divide 73843056 by 645
We want to divide 73843056 by 645.

On to step 1:
If we divide 7 by 645, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 645

On to step 2:
When dividing 73 by 645, we get 0 with a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Append the next digit (8) from the dividend to 73 and continue with: 738 / 645

Let's proceed to step 3:
738 divided by 645 is 1 with a remainder of 93.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 645 from 738, we get 93.
Append the next digit (4) from the dividend to 93 and continue with: 934 / 645

Moving on to step 4:
645 goes into 934 1 times with a remainder of 289.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 645 away from 934, we end up with 289.
Append the next digit (3) from the dividend to 289 and continue with: 2893 / 645

Step 5:
If we divide 2893 by 645, we get 4 and a remainder of 313.
Use 4 as the next digit of our solution. 
Result so far: 114.0
If we take 2580 away from 2893, we end up with 313.
Append the next digit (0) from the dividend to 313 and continue with: 3130 / 645

Step 6:
645 can be fit into 3130 4 times, resulting in a remainder of 550.
The next digit of our result is 4. 
Result so far: 1144.0
If we take 2580 away from 3130, we end up with 550.
Fetch the next digit (5) from the dividend, attach it to 550 and continue: 5505 / 645

On to step 7:
When dividing 5505 by 645, we get 8 with a remainder of 345.
Use 8 as the next digit of our solution. 
Result so far: 11448.0
Subtract 5160 from 5505 to get 345.
Include the next digit (6) from the dividend after 345, then repeat: 3456 / 645

Going ahead to step 8:
The number 645 fits into 3456 5 times, leaving a remainder of 231.
Use 5 as the next digit of our solution. 
Result so far: 114485.0
If we subtract 3225 from 3456, we get 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Advancing to step 9:
If we divide 2310 by 645, we get 3 and a remainder of 375.
Use 3 as the next digit of our solution. 
Result so far: 114485.3
Subtract 1935 from 2310 to get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Going ahead to step 10:
If we divide 3750 by 645, we get 5 and a remainder of 525.
The number 5 becomes the next digit in our result. 
Result so far: 114485.35
Subtracting 3225 from 3750 leaves us with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Advancing to step 11:
645 can be fit into 5250 8 times, resulting in a remainder of 90.
Write down 8 as next digit of the result. 
Result so far: 114485.358
If we subtract 5160 from 5250, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 12:
645 can be fit into 900 1 times, resulting in a remainder of 255.
The number 1 becomes the next digit in our result. 
Result so far: 114485.3581
If we take 645 away from 900, we end up with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Step 13:
If we divide 2550 by 645, we get 3 and a remainder of 615.
Write down 3 as next digit of the result. 
Result so far: 114485.35813
If we take 1935 away from 2550, we end up with 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Let's proceed to step 14:
If we divide 6150 by 645, we get 9 and a remainder of 345.
The next digit of our result is 9. 
Result so far: 114485.358139
The remainder is 345 after subtracting 5805 from 6150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Advancing to step 15:
3450 divided by 645 is 5 with a remainder of 225.
Use 5 as the next digit of our solution. 
Result so far: 114485.3581395
If we take 3225 away from 3450, we end up with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Let's proceed to step 16:
When dividing 2250 by 645, we get 3 with a remainder of 315.
Use 3 as the next digit of our solution. 
Result so far: 114485.35813953
If we take 1935 away from 2250, we end up with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

The final outcome is 114485.35813953, with a leftover of 3.15e-07.
