851138 ÷ 39 
We want to divide 851138 by 39.

Moving on to step 1:
39 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 39

Going ahead to step 2:
39 goes into 85 2 times with a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 78 from 85, we get 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 39

On to step 3:
If we divide 71 by 39, we get 1 and a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 21.0
The remainder is 32 after subtracting 39 from 71.
Grab the next digit (1) from the dividend, add it to 32, then carry on: 321 / 39

Step 4:
The number 39 fits into 321 8 times, leaving a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 218.0
If we take 312 away from 321, we end up with 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 39

Step 5:
93 divided by 39 is 2 with a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 2182.0
If we subtract 78 from 93, we get 15.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 39

Step 6:
When dividing 158 by 39, we get 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 21824.0
The remainder is 2 after subtracting 156 from 158.
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 7:
The number 39 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 21824.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
39 can be fit into 200 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 21824.05
Deduct 195 from 200 and we're left with 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 9:
50 divided by 39 is 1 with a remainder of 11.
The next digit of our result is 1. 
Result so far: 21824.051
The remainder is 11 after subtracting 39 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 10:
The number 39 fits into 110 2 times, leaving a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 21824.0512
Subtracting 78 from 110 leaves us with 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 11:
If we divide 320 by 39, we get 8 and a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 21824.05128
If we take 312 away from 320, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 12:
When dividing 80 by 39, we get 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 21824.051282
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.

Step 13:
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: 21824.051282
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.

Let's proceed to step 14:
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: 21824.05128205
The remainder is 5 after subtracting 195 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 21824.05128205 with a remaining 5e-09.
