210857 ÷ 47 
Our goal is to divide 210857 by 47.

Let's proceed to step 1:
When dividing 2 by 47, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 47

Let's proceed to step 2:
When dividing 21 by 47, we get 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Take the next digit (0) from the dividend and append it to 21, then repeat: 210 / 47

On to step 3:
47 can be fit into 210 4 times, resulting in a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 188 from 210 leaves us with 22.
Fetch the next digit (8) from the dividend, attach it to 22 and continue: 228 / 47

Moving on to step 4:
47 goes into 228 4 times with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 44.0
Subtracting 188 from 228 leaves us with 40.
Bring next digit (5) of the dividend behind the 40 and repeat the process: 405 / 47

On to step 5:
47 can be fit into 405 8 times, resulting in a remainder of 29.
The number 8 becomes the next digit in our result. 
Result so far: 448.0
If we take 376 away from 405, we end up with 29.
Grab the next digit (7) from the dividend, add it to 29, then carry on: 297 / 47

Let's proceed to step 6:
47 goes into 297 6 times with a remainder of 15.
Write down 6 as next digit of the result. 
Result so far: 4486.0
If we take 282 away from 297, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
47 can be fit into 150 3 times, resulting in a remainder of 9.
The next digit of our result is 3. 
Result so far: 4486.3
Deduct 141 from 150 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 8:
90 divided by 47 is 1 with a remainder of 43.
Write down 1 as next digit of the result. 
Result so far: 4486.31
Subtract 47 from 90 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 9:
47 goes into 430 9 times with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 4486.319
Subtract 423 from 430 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 10:
When dividing 70 by 47, we get 1 with a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 4486.3191
If we take 47 away from 70, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 11:
When dividing 230 by 47, we get 4 with a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 4486.31914
If we take 188 away from 230, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 12:
The number 47 fits into 420 8 times, leaving a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 4486.319148
If we take 376 away from 420, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 13:
440 divided by 47 is 9 with a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 4486.3191489
If we take 423 away from 440, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 14:
When dividing 170 by 47, we get 3 with a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 4486.31914893
Subtracting 141 from 170 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final outcome is 4486.31914893, with a leftover of 2.9e-08.
