We're dividing 39579432 by 845 
Our goal is to divide 39579432 by 845.

Let's proceed to step 1:
The number 845 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 845

Going ahead to step 2:
When dividing 39 by 845, we get 0 with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Append the next digit (5) from the dividend to 39 and continue with: 395 / 845

Going ahead to step 3:
845 goes into 395 0 times with a remainder of 395.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 395 leaves us with 395.
Append the next digit (7) from the dividend to 395 and continue with: 3957 / 845

On to step 4:
When dividing 3957 by 845, we get 4 with a remainder of 577.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 3380 from 3957 to get 577.
Bring next digit (9) of the dividend behind the 577 and repeat the process: 5779 / 845

Let's proceed to step 5:
When dividing 5779 by 845, we get 6 with a remainder of 709.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
If we subtract 5070 from 5779, we get 709.
Grab the next digit (4) from the dividend, add it to 709, then carry on: 7094 / 845

Going ahead to step 6:
845 goes into 7094 8 times with a remainder of 334.
Record the quotient 8 as the next digit in the result. 
Result so far: 468.0
Subtract 6760 from 7094 to get 334.
Include the next digit (3) from the dividend after 334, then repeat: 3343 / 845

Let's proceed to step 7:
3343 divided by 845 is 3 with a remainder of 808.
Put 3 as the next digit of the answer. 
Result so far: 4683.0
Deduct 2535 from 3343 and we're left with 808.
Append the next digit (2) from the dividend to 808 and continue with: 8082 / 845

Step 8:
If we divide 8082 by 845, we get 9 and a remainder of 477.
Put 9 as the next digit of the answer. 
Result so far: 46839.0
Subtract 7605 from 8082 to get 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

On to step 9:
The number 845 fits into 4770 5 times, leaving a remainder of 545.
The next digit of our result is 5. 
Result so far: 46839.5
Subtracting 4225 from 4770 leaves us with 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Let's proceed to step 10:
5450 divided by 845 is 6 with a remainder of 380.
The number 6 becomes the next digit in our result. 
Result so far: 46839.56
Subtract 5070 from 5450 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 11:
If we divide 3800 by 845, we get 4 and a remainder of 420.
Use 4 as the next digit of our solution. 
Result so far: 46839.564
If we take 3380 away from 3800, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Step 12:
845 goes into 4200 4 times with a remainder of 820.
The number 4 becomes the next digit in our result. 
Result so far: 46839.5644
Subtracting 3380 from 4200 leaves us with 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

The final result is 46839.5644 with a remainder of 0.0082.
