We're dividing 390183 by 53 
We want to figure out the number of times 390183 can be divided by 53.

On to step 1:
The number 53 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 53

Moving on to step 2:
53 can be fit into 39 0 times, resulting in a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Fetch the next digit (0) from the dividend, attach it to 39 and continue: 390 / 53

Advancing to step 3:
53 can be fit into 390 7 times, resulting in a remainder of 19.
The next digit of our result is 7. 
Result so far: 7.0
If we take 371 away from 390, we end up with 19.
Append the next digit (1) from the dividend to 19 and continue with: 191 / 53

Advancing to step 4:
If we divide 191 by 53, we get 3 and a remainder of 32.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
If we subtract 159 from 191, we get 32.
Include the next digit (8) from the dividend after 32, then repeat: 328 / 53

Let's proceed to step 5:
The number 53 fits into 328 6 times, leaving a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 736.0
Deduct 318 from 328 and we're left with 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 53

Advancing to step 6:
53 goes into 103 1 times with a remainder of 50.
Write down 1 as next digit of the result. 
Result so far: 7361.0
Subtracting 53 from 103 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 7:
When dividing 500 by 53, we get 9 with a remainder of 23.
The next digit of our result is 9. 
Result so far: 7361.9
Subtracting 477 from 500 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 8:
230 divided by 53 is 4 with a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 7361.94
Subtract 212 from 230 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 9:
If we divide 180 by 53, we get 3 and a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 7361.943
Subtract 159 from 180 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 10:
53 goes into 210 3 times with a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 7361.9433
Subtract 159 from 210 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The final outcome is 7361.9433, with a leftover of 0.00051.
