39999731 divided by 945 
Our goal is to divide 39999731 by 945.

Moving on to step 1:
3 divided by 945 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 945

Step 2:
945 can be fit into 39 0 times, resulting in a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Take the next digit (9) from the dividend and append it to 39, then repeat: 399 / 945

On to step 3:
399 divided by 945 is 0 with a remainder of 399.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 399 after subtracting 0 from 399.
Fetch the next digit (9) from the dividend, attach it to 399 and continue: 3999 / 945

Let's proceed to step 4:
If we divide 3999 by 945, we get 4 and a remainder of 219.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 3780 from 3999 leaves us with 219.
Append the next digit (9) from the dividend to 219 and continue with: 2199 / 945

Let's proceed to step 5:
If we divide 2199 by 945, we get 2 and a remainder of 309.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
The remainder is 309 after subtracting 1890 from 2199.
Bring next digit (7) of the dividend behind the 309 and repeat the process: 3097 / 945

Let's proceed to step 6:
945 can be fit into 3097 3 times, resulting in a remainder of 262.
Put 3 as the next digit of the answer. 
Result so far: 423.0
Subtract 2835 from 3097 to get 262.
Take the next digit (3) from the dividend and append it to 262, then repeat: 2623 / 945

Let's proceed to step 7:
2623 divided by 945 is 2 with a remainder of 733.
Write down 2 as next digit of the result. 
Result so far: 4232.0
Subtracting 1890 from 2623 leaves us with 733.
Append the next digit (1) from the dividend to 733 and continue with: 7331 / 945

Advancing to step 8:
The number 945 fits into 7331 7 times, leaving a remainder of 716.
Put 7 as the next digit of the answer. 
Result so far: 42327.0
The remainder is 716 after subtracting 6615 from 7331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7160, and continue the process.

Moving on to step 9:
7160 divided by 945 is 7 with a remainder of 545.
Use 7 as the next digit of our solution. 
Result so far: 42327.7
If we subtract 6615 from 7160, we get 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Step 10:
945 can be fit into 5450 5 times, resulting in a remainder of 725.
Use 5 as the next digit of our solution. 
Result so far: 42327.75
Subtract 4725 from 5450 to get 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

On to step 11:
945 can be fit into 7250 7 times, resulting in a remainder of 635.
Use 7 as the next digit of our solution. 
Result so far: 42327.757
If we take 6615 away from 7250, we end up with 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

On to step 12:
945 goes into 6350 6 times with a remainder of 680.
The number 6 becomes the next digit in our result. 
Result so far: 42327.7576
Deduct 5670 from 6350 and we're left with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Let's proceed to step 13:
945 can be fit into 6800 7 times, resulting in a remainder of 185.
The number 7 becomes the next digit in our result. 
Result so far: 42327.75767
Deduct 6615 from 6800 and we're left with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

On to step 14:
If we divide 1850 by 945, we get 1 and a remainder of 905.
Record the quotient 1 as the next digit in the result. 
Result so far: 42327.757671
If we take 945 away from 1850, we end up with 905.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9050, and continue the process.

Advancing to step 15:
9050 divided by 945 is 9 with a remainder of 545.
Use 9 as the next digit of our solution. 
Result so far: 42327.7576719
If we take 8505 away from 9050, we end up 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.

Advancing to step 16:
5450 divided by 945 is 5 with a remainder of 725.
The number 5 becomes the next digit in our result. 
Result so far: 42327.75767195
Subtract 4725 from 5450 to get 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

The final outcome is 42327.75767195, with a leftover of 7.25e-07.
