286943 ÷ 39 
Our goal is to divide 286943 by 39.

Step 1:
If we divide 2 by 39, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 39

Let's proceed to step 2:
28 divided by 39 is 0 with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Grab the next digit (6) from the dividend, add it to 28, then carry on: 286 / 39

Step 3:
If we divide 286 by 39, we get 7 and a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 273 from 286, we get 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 39

Going ahead to step 4:
If we divide 139 by 39, we get 3 and a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
If we take 117 away from 139, we end up with 22.
Take the next digit (4) from the dividend and append it to 22, then repeat: 224 / 39

Let's proceed to step 5:
The number 39 fits into 224 5 times, leaving a remainder of 29.
The number 5 becomes the next digit in our result. 
Result so far: 735.0
Subtract 195 from 224 to get 29.
Append the next digit (3) from the dividend to 29 and continue with: 293 / 39

On to step 6:
39 can be fit into 293 7 times, resulting in a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 7357.0
Deduct 273 from 293 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 7:
39 can be fit into 200 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 7357.5
If we subtract 195 from 200, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
The number 39 fits into 50 1 times, leaving a remainder of 11.
The next digit of our result is 1. 
Result so far: 7357.51
Deduct 39 from 50 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
When dividing 110 by 39, we get 2 with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 7357.512
If we subtract 78 from 110, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 10:
320 divided by 39 is 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 7357.5128
The remainder is 8 after subtracting 312 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
When dividing 80 by 39, we get 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 7357.51282
If we take 78 away from 80, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 12:
When dividing 20 by 39, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 7357.51282
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
If we divide 200 by 39, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 7357.5128205
Subtract 195 from 200 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 14:
The number 39 fits into 50 1 times, leaving a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 7357.51282051
Deduct 39 from 50 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

After the division, we end up with 7357.51282051 and a remainder of 1.1e-08.
