210669 ÷ 79 
We want to divide 210669 by 79.

Let's proceed to step 1:
79 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 79

Moving on to step 2:
79 goes into 21 0 times with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Fetch the next digit (0) from the dividend, attach it to 21 and continue: 210 / 79

Moving on to step 3:
210 divided by 79 is 2 with a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 158 from 210 to get 52.
Include the next digit (6) from the dividend after 52, then repeat: 526 / 79

Moving on to step 4:
When dividing 526 by 79, we get 6 with a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 26.0
Subtract 474 from 526 to get 52.
Append the next digit (6) from the dividend to 52 and continue with: 526 / 79

On to step 5:
The number 79 fits into 526 6 times, leaving a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 266.0
The remainder is 52 after subtracting 474 from 526.
Append the next digit (9) from the dividend to 52 and continue with: 529 / 79

Let's proceed to step 6:
When dividing 529 by 79, we get 6 with a remainder of 55.
Use 6 as the next digit of our solution. 
Result so far: 2666.0
If we take 474 away from 529, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 7:
The number 79 fits into 550 6 times, leaving a remainder of 76.
Use 6 as the next digit of our solution. 
Result so far: 2666.6
Subtract 474 from 550 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 8:
If we divide 760 by 79, we get 9 and a remainder of 49.
The number 9 becomes the next digit in our result. 
Result so far: 2666.69
Subtract 711 from 760 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 9:
490 divided by 79 is 6 with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 2666.696
Deduct 474 from 490 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
79 goes into 160 2 times with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 2666.6962
Subtracting 158 from 160 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.

Step 11:
The number 79 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 2666.6962
Deduct 0 from 20 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.

Advancing to step 12:
79 goes into 200 2 times with a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 2666.696202
Subtracting 158 from 200 leaves us 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.

Let's proceed to step 13:
79 can be fit into 420 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 2666.6962025
The remainder is 25 after subtracting 395 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 14:
79 goes into 250 3 times with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 2666.69620253
Deduct 237 from 250 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final result is 2666.69620253 with a remainder of 1.3e-08.
