We're dividing 373863 by 39 
We want to divide 373863 by 39.

Moving on to step 1:
39 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 39

On to step 2:
39 can be fit into 37 0 times, resulting in a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 37 leaves us with 37.
Take the next digit (3) from the dividend and append it to 37, then repeat: 373 / 39

Moving on to step 3:
If we divide 373 by 39, we get 9 and a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 351 away from 373, we end up with 22.
Append the next digit (8) from the dividend to 22 and continue with: 228 / 39

Moving on to step 4:
39 goes into 228 5 times with a remainder of 33.
Put 5 as the next digit of the answer. 
Result so far: 95.0
If we subtract 195 from 228, we get 33.
Include the next digit (6) from the dividend after 33, then repeat: 336 / 39

Moving on to step 5:
39 goes into 336 8 times with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 958.0
Deduct 312 from 336 and we're left with 24.
Fetch the next digit (3) from the dividend, attach it to 24 and continue: 243 / 39

Moving on to step 6:
243 divided by 39 is 6 with a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 9586.0
The remainder is 9 after subtracting 234 from 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
When dividing 90 by 39, we get 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 9586.2
Deduct 78 from 90 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
39 can be fit into 120 3 times, resulting in a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 9586.23
Deduct 117 from 120 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 9:
When dividing 30 by 39, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 9586.23
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
39 goes into 300 7 times with a remainder of 27.
The next digit of our result is 7. 
Result so far: 9586.2307
The remainder is 27 after subtracting 273 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 11:
When dividing 270 by 39, we get 6 with a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 9586.23076
If we take 234 away from 270, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 12:
The number 39 fits into 360 9 times, leaving a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 9586.230769
Subtract 351 from 360 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 13:
90 divided by 39 is 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 9586.2307692
If we take 78 away from 90, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 14:
When dividing 120 by 39, we get 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 9586.23076923
Subtracting 117 from 120 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Our division results in 9586.23076923 with a remaining 3e-09.
