Let's divide 25531309 by 939
We're looking to find how many times 939 goes into 25531309.

On to step 1:
When dividing 2 by 939, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 939

Going ahead to step 2:
The number 939 fits into 25 0 times, leaving a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Fetch the next digit (5) from the dividend, attach it to 25 and continue: 255 / 939

Going ahead to step 3:
The number 939 fits into 255 0 times, leaving a remainder of 255.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 255 leaves us with 255.
Include the next digit (3) from the dividend after 255, then repeat: 2553 / 939

Moving on to step 4:
2553 divided by 939 is 2 with a remainder of 675.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 675 after subtracting 1878 from 2553.
Append the next digit (1) from the dividend to 675 and continue with: 6751 / 939

Moving on to step 5:
6751 divided by 939 is 7 with a remainder of 178.
The next digit of our result is 7. 
Result so far: 27.0
If we subtract 6573 from 6751, we get 178.
Grab the next digit (3) from the dividend, add it to 178, then carry on: 1783 / 939

Let's proceed to step 6:
The number 939 fits into 1783 1 times, leaving a remainder of 844.
Record the quotient 1 as the next digit in the result. 
Result so far: 271.0
The remainder is 844 after subtracting 939 from 1783.
Bring next digit (0) of the dividend behind the 844 and repeat the process: 8440 / 939

Step 7:
939 can be fit into 8440 8 times, resulting in a remainder of 928.
The next digit of our result is 8. 
Result so far: 2718.0
If we take 7512 away from 8440, we end up with 928.
Append the next digit (9) from the dividend to 928 and continue with: 9289 / 939

Advancing to step 8:
If we divide 9289 by 939, we get 9 and a remainder of 838.
Use 9 as the next digit of our solution. 
Result so far: 27189.0
If we take 8451 away from 9289, we end up with 838.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8380, and continue the process.

Step 9:
939 can be fit into 8380 8 times, resulting in a remainder of 868.
The number 8 becomes the next digit in our result. 
Result so far: 27189.8
The remainder is 868 after subtracting 7512 from 8380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8680, and continue the process.

On to step 10:
The number 939 fits into 8680 9 times, leaving a remainder of 229.
Put 9 as the next digit of the answer. 
Result so far: 27189.89
If we subtract 8451 from 8680, we get 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Let's proceed to step 11:
If we divide 2290 by 939, we get 2 and a remainder of 412.
Put 2 as the next digit of the answer. 
Result so far: 27189.892
If we take 1878 away from 2290, we end up with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Moving on to step 12:
When dividing 4120 by 939, we get 4 with a remainder of 364.
Use 4 as the next digit of our solution. 
Result so far: 27189.8924
If we take 3756 away from 4120, we end up with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Moving on to step 13:
The number 939 fits into 3640 3 times, leaving a remainder of 823.
Put 3 as the next digit of the answer. 
Result so far: 27189.89243
Deduct 2817 from 3640 and we're left with 823.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8230, and continue the process.

Step 14:
The number 939 fits into 8230 8 times, leaving a remainder of 718.
Put 8 as the next digit of the answer. 
Result so far: 27189.892438
If we take 7512 away from 8230, we end up with 718.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7180, and continue the process.

On to step 15:
7180 divided by 939 is 7 with a remainder of 607.
The number 7 becomes the next digit in our result. 
Result so far: 27189.8924387
Deduct 6573 from 7180 and we're left with 607.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

Step 16:
If we divide 6070 by 939, we get 6 and a remainder of 436.
Use 6 as the next digit of our solution. 
Result so far: 27189.89243876
If we subtract 5634 from 6070, we get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

The final result is 27189.89243876 with a remainder of 4.36e-07.
