857573 ÷ 39 
Our goal is to divide 857573 by 39.

On to step 1:
39 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 39

Let's proceed to step 2:
39 can be fit into 85 2 times, resulting in a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 78 from 85, we get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 39

Advancing to step 3:
39 can be fit into 77 1 times, resulting in a remainder of 38.
The next digit of our result is 1. 
Result so far: 21.0
Subtract 39 from 77 to get 38.
Bring next digit (5) of the dividend behind the 38 and repeat the process: 385 / 39

Going ahead to step 4:
If we divide 385 by 39, we get 9 and a remainder of 34.
The next digit of our result is 9. 
Result so far: 219.0
Subtract 351 from 385 to get 34.
Include the next digit (7) from the dividend after 34, then repeat: 347 / 39

Step 5:
39 can be fit into 347 8 times, resulting in a remainder of 35.
Record the quotient 8 as the next digit in the result. 
Result so far: 2198.0
If we take 312 away from 347, we end up with 35.
Grab the next digit (3) from the dividend, add it to 35, then carry on: 353 / 39

Moving on to step 6:
39 goes into 353 9 times with a remainder of 2.
The next digit of our result is 9. 
Result so far: 21989.0
If we subtract 351 from 353, we get 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 7:
20 divided by 39 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 21989.0
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.

Moving on to step 8:
200 divided by 39 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 21989.05
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.

Advancing to step 9:
When dividing 50 by 39, we get 1 with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 21989.051
If we take 39 away from 50, we end up 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.

On to step 10:
When dividing 110 by 39, we get 2 with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 21989.0512
Subtract 78 from 110 to 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.

Going ahead to step 11:
The number 39 fits into 320 8 times, leaving a remainder of 8.
The next digit of our result is 8. 
Result so far: 21989.05128
Subtract 312 from 320 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
When dividing 80 by 39, we get 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 21989.051282
Subtracting 78 from 80 leaves us 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 13:
20 divided by 39 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 21989.051282
Subtracting 0 from 20 leaves us 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.

Advancing to step 14:
39 goes into 200 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 21989.05128205
Subtracting 195 from 200 leaves us 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.

After the division, we end up with 21989.05128205 and a remainder of 5e-09.
