We're dividing 39872177 by 939 
Our goal is to divide 39872177 by 939.

Going ahead to step 1:
The number 939 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
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 / 939

Let's proceed to step 2:
39 divided by 939 is 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Append the next digit (8) from the dividend to 39 and continue with: 398 / 939

Advancing to step 3:
939 goes into 398 0 times with a remainder of 398.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 398 and we're left with 398.
Append the next digit (7) from the dividend to 398 and continue with: 3987 / 939

Advancing to step 4:
The number 939 fits into 3987 4 times, leaving a remainder of 231.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 3756 from 3987 to get 231.
Grab the next digit (2) from the dividend, add it to 231, then carry on: 2312 / 939

Moving on to step 5:
939 goes into 2312 2 times with a remainder of 434.
Write down 2 as next digit of the result. 
Result so far: 42.0
Subtracting 1878 from 2312 leaves us with 434.
Bring next digit (1) of the dividend behind the 434 and repeat the process: 4341 / 939

On to step 6:
939 can be fit into 4341 4 times, resulting in a remainder of 585.
Put 4 as the next digit of the answer. 
Result so far: 424.0
If we take 3756 away from 4341, we end up with 585.
Include the next digit (7) from the dividend after 585, then repeat: 5857 / 939

Advancing to step 7:
The number 939 fits into 5857 6 times, leaving a remainder of 223.
The number 6 becomes the next digit in our result. 
Result so far: 4246.0
Deduct 5634 from 5857 and we're left with 223.
Grab the next digit (7) from the dividend, add it to 223, then carry on: 2237 / 939

Let's proceed to step 8:
When dividing 2237 by 939, we get 2 with a remainder of 359.
Put 2 as the next digit of the answer. 
Result so far: 42462.0
Subtracting 1878 from 2237 leaves us with 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Moving on to step 9:
939 can be fit into 3590 3 times, resulting in a remainder of 773.
The next digit of our result is 3. 
Result so far: 42462.3
The remainder is 773 after subtracting 2817 from 3590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7730, and continue the process.

Moving on to step 10:
When dividing 7730 by 939, we get 8 with a remainder of 218.
Record the quotient 8 as the next digit in the result. 
Result so far: 42462.38
Subtracting 7512 from 7730 leaves us with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Step 11:
939 can be fit into 2180 2 times, resulting in a remainder of 302.
The number 2 becomes the next digit in our result. 
Result so far: 42462.382
Subtract 1878 from 2180 to get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Let's proceed to step 12:
If we divide 3020 by 939, we get 3 and a remainder of 203.
Use 3 as the next digit of our solution. 
Result so far: 42462.3823
Deduct 2817 from 3020 and we're left with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Going ahead to step 13:
The number 939 fits into 2030 2 times, leaving a remainder of 152.
Record the quotient 2 as the next digit in the result. 
Result so far: 42462.38232
If we take 1878 away from 2030, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 14:
If we divide 1520 by 939, we get 1 and a remainder of 581.
Put 1 as the next digit of the answer. 
Result so far: 42462.382321
If we take 939 away from 1520, we end up with 581.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5810, and continue the process.

Advancing to step 15:
If we divide 5810 by 939, we get 6 and a remainder of 176.
The number 6 becomes the next digit in our result. 
Result so far: 42462.3823216
The remainder is 176 after subtracting 5634 from 5810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 16:
The number 939 fits into 1760 1 times, leaving a remainder of 821.
Write down 1 as next digit of the result. 
Result so far: 42462.38232161
The remainder is 821 after subtracting 939 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8210, and continue the process.

Our division results in 42462.38232161 with a remaining 8.21e-07.
