We're dividing 73700393 by 486 
We want to figure out the number of times 73700393 can be divided by 486.

Let's proceed to step 1:
7 divided by 486 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 486

Advancing to step 2:
The number 486 fits into 73 0 times, leaving a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Append the next digit (7) from the dividend to 73 and continue with: 737 / 486

Let's proceed to step 3:
737 divided by 486 is 1 with a remainder of 251.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 486 from 737, we get 251.
Include the next digit (0) from the dividend after 251, then repeat: 2510 / 486

Let's proceed to step 4:
The number 486 fits into 2510 5 times, leaving a remainder of 80.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 2430 from 2510, we get 80.
Fetch the next digit (0) from the dividend, attach it to 80 and continue: 800 / 486

On to step 5:
486 goes into 800 1 times with a remainder of 314.
Put 1 as the next digit of the answer. 
Result so far: 151.0
If we subtract 486 from 800, we get 314.
Grab the next digit (3) from the dividend, add it to 314, then carry on: 3143 / 486

On to step 6:
486 goes into 3143 6 times with a remainder of 227.
Use 6 as the next digit of our solution. 
Result so far: 1516.0
If we subtract 2916 from 3143, we get 227.
Append the next digit (9) from the dividend to 227 and continue with: 2279 / 486

Step 7:
If we divide 2279 by 486, we get 4 and a remainder of 335.
Write down 4 as next digit of the result. 
Result so far: 15164.0
The remainder is 335 after subtracting 1944 from 2279.
Grab the next digit (3) from the dividend, add it to 335, then carry on: 3353 / 486

On to step 8:
The number 486 fits into 3353 6 times, leaving a remainder of 437.
The number 6 becomes the next digit in our result. 
Result so far: 151646.0
Subtract 2916 from 3353 to get 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Step 9:
486 goes into 4370 8 times with a remainder of 482.
Put 8 as the next digit of the answer. 
Result so far: 151646.8
The remainder is 482 after subtracting 3888 from 4370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Step 10:
4820 divided by 486 is 9 with a remainder of 446.
The next digit of our result is 9. 
Result so far: 151646.89
The remainder is 446 after subtracting 4374 from 4820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Moving on to step 11:
When dividing 4460 by 486, we get 9 with a remainder of 86.
Write down 9 as next digit of the result. 
Result so far: 151646.899
If we take 4374 away from 4460, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Our division results in 151646.899 with a remaining 0.0086.
