38639438 divided by 940 
We want to figure out the number of times 38639438 can be divided by 940.

Step 1:
If we divide 3 by 940, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 940

Advancing to step 2:
If we divide 38 by 940, we get 0 and a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Include the next digit (6) from the dividend after 38, then repeat: 386 / 940

On to step 3:
940 can be fit into 386 0 times, resulting in a remainder of 386.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 386 leaves us with 386.
Append the next digit (3) from the dividend to 386 and continue with: 3863 / 940

On to step 4:
940 can be fit into 3863 4 times, resulting in a remainder of 103.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 3760 from 3863, we get 103.
Include the next digit (9) from the dividend after 103, then repeat: 1039 / 940

On to step 5:
1039 divided by 940 is 1 with a remainder of 99.
The next digit of our result is 1. 
Result so far: 41.0
Subtracting 940 from 1039 leaves us with 99.
Grab the next digit (4) from the dividend, add it to 99, then carry on: 994 / 940

Moving on to step 6:
If we divide 994 by 940, we get 1 and a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 411.0
If we take 940 away from 994, we end up with 54.
Bring next digit (3) of the dividend behind the 54 and repeat the process: 543 / 940

Moving on to step 7:
940 goes into 543 0 times with a remainder of 543.
Use 0 as the next digit of our solution. 
Result so far: 4110.0
If we take 0 away from 543, we end up with 543.
Fetch the next digit (8) from the dividend, attach it to 543 and continue: 5438 / 940

Step 8:
940 goes into 5438 5 times with a remainder of 738.
Use 5 as the next digit of our solution. 
Result so far: 41105.0
Subtract 4700 from 5438 to get 738.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7380, and continue the process.

Moving on to step 9:
7380 divided by 940 is 7 with a remainder of 800.
Write down 7 as next digit of the result. 
Result so far: 41105.7
Subtracting 6580 from 7380 leaves us with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

On to step 10:
8000 divided by 940 is 8 with a remainder of 480.
Write down 8 as next digit of the result. 
Result so far: 41105.78
Subtracting 7520 from 8000 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 11:
4800 divided by 940 is 5 with a remainder of 100.
Put 5 as the next digit of the answer. 
Result so far: 41105.785
The remainder is 100 after subtracting 4700 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 12:
If we divide 1000 by 940, we get 1 and a remainder of 60.
The number 1 becomes the next digit in our result. 
Result so far: 41105.7851
Deduct 940 from 1000 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 13:
The number 940 fits into 600 0 times, leaving a remainder of 600.
Use 0 as the next digit of our solution. 
Result so far: 41105.7851
If we subtract 0 from 600, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 14:
If we divide 6000 by 940, we get 6 and a remainder of 360.
Write down 6 as next digit of the result. 
Result so far: 41105.785106
The remainder is 360 after subtracting 5640 from 6000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 15:
If we divide 3600 by 940, we get 3 and a remainder of 780.
Put 3 as the next digit of the answer. 
Result so far: 41105.7851063
If we take 2820 away from 3600, we end up with 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Going ahead to step 16:
7800 divided by 940 is 8 with a remainder of 280.
Record the quotient 8 as the next digit in the result. 
Result so far: 41105.78510638
If we subtract 7520 from 7800, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

After the division, we end up with 41105.78510638 and a remainder of 2.8e-07.
