We divide 73863484 by 644
Our goal is to divide 73863484 by 644.

Moving on to step 1:
When dividing 7 by 644, we get 0 with 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 / 644

On to step 2:
644 goes into 73 0 times with a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 73 to get 73.
Include the next digit (8) from the dividend after 73, then repeat: 738 / 644

Moving on to step 3:
When dividing 738 by 644, we get 1 with a remainder of 94.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 644 from 738 leaves us with 94.
Fetch the next digit (6) from the dividend, attach it to 94 and continue: 946 / 644

Going ahead to step 4:
644 can be fit into 946 1 times, resulting in a remainder of 302.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 644 from 946 leaves us with 302.
Bring next digit (3) of the dividend behind the 302 and repeat the process: 3023 / 644

Let's proceed to step 5:
3023 divided by 644 is 4 with a remainder of 447.
Use 4 as the next digit of our solution. 
Result so far: 114.0
If we take 2576 away from 3023, we end up with 447.
Append the next digit (4) from the dividend to 447 and continue with: 4474 / 644

On to step 6:
644 can be fit into 4474 6 times, resulting in a remainder of 610.
Write down 6 as next digit of the result. 
Result so far: 1146.0
Subtracting 3864 from 4474 leaves us with 610.
Fetch the next digit (8) from the dividend, attach it to 610 and continue: 6108 / 644

Step 7:
6108 divided by 644 is 9 with a remainder of 312.
Put 9 as the next digit of the answer. 
Result so far: 11469.0
If we subtract 5796 from 6108, we get 312.
Bring next digit (4) of the dividend behind the 312 and repeat the process: 3124 / 644

Advancing to step 8:
When dividing 3124 by 644, we get 4 with a remainder of 548.
Record the quotient 4 as the next digit in the result. 
Result so far: 114694.0
Deduct 2576 from 3124 and we're left with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Advancing to step 9:
5480 divided by 644 is 8 with a remainder of 328.
Put 8 as the next digit of the answer. 
Result so far: 114694.8
The remainder is 328 after subtracting 5152 from 5480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Let's proceed to step 10:
When dividing 3280 by 644, we get 5 with a remainder of 60.
The next digit of our result is 5. 
Result so far: 114694.85
If we subtract 3220 from 3280, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
644 can be fit into 600 0 times, resulting in a remainder of 600.
Record the quotient 0 as the next digit in the result. 
Result so far: 114694.85
Deduct 0 from 600 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 12:
644 can be fit into 6000 9 times, resulting in a remainder of 204.
The next digit of our result is 9. 
Result so far: 114694.8509
The remainder is 204 after subtracting 5796 from 6000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Advancing to step 13:
2040 divided by 644 is 3 with a remainder of 108.
The next digit of our result is 3. 
Result so far: 114694.85093
The remainder is 108 after subtracting 1932 from 2040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 14:
The number 644 fits into 1080 1 times, leaving a remainder of 436.
Put 1 as the next digit of the answer. 
Result so far: 114694.850931
Deduct 644 from 1080 and we're left with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

On to step 15:
644 goes into 4360 6 times with a remainder of 496.
Use 6 as the next digit of our solution. 
Result so far: 114694.8509316
Deduct 3864 from 4360 and we're left with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Step 16:
644 goes into 4960 7 times with a remainder of 452.
Write down 7 as next digit of the result. 
Result so far: 114694.85093167
If we take 4508 away from 4960, we end up 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.

The final result is 114694.85093167 with a remainder of 4.52e-07.
