Let's divide 39405 by 57
We want to divide 39405 by 57.

Let's proceed to step 1:
When dividing 3 by 57, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 57

Moving on to step 2:
If we divide 39 by 57, we get 0 and a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Bring next digit (4) of the dividend behind the 39 and repeat the process: 394 / 57

Advancing to step 3:
When dividing 394 by 57, we get 6 with a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 342 from 394 and we're left with 52.
Fetch the next digit (0) from the dividend, attach it to 52 and continue: 520 / 57

On to step 4:
57 can be fit into 520 9 times, resulting in a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 69.0
If we take 513 away from 520, we end up with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 57

Advancing to step 5:
When dividing 75 by 57, we get 1 with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 691.0
If we take 57 away from 75, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 6:
57 can be fit into 180 3 times, resulting in a remainder of 9.
The next digit of our result is 3. 
Result so far: 691.3
Deduct 171 from 180 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
57 can be fit into 90 1 times, resulting in a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 691.31
If we subtract 57 from 90, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 8:
57 can be fit into 330 5 times, resulting in a remainder of 45.
The next digit of our result is 5. 
Result so far: 691.315
Subtract 285 from 330 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 9:
If we divide 450 by 57, we get 7 and a remainder of 51.
Write down 7 as next digit of the result. 
Result so far: 691.3157
Subtract 399 from 450 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.

Going ahead to step 10:
When dividing 510 by 57, we get 8 with a remainder of 54.
Use 8 as the next digit of our solution. 
Result so far: 691.31578
Subtract 456 from 510 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 11:
When dividing 540 by 57, we get 9 with a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 691.315789
Deduct 513 from 540 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 12:
57 goes into 270 4 times with a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 691.3157894
Deduct 228 from 270 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 13:
The number 57 fits into 420 7 times, leaving a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 691.31578947
Deduct 399 from 420 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

In conclusion, the division gives 691.31578947 with a balance of 2.1e-08.
