We look at the division of 210040 by 79 
Our goal is to divide 210040 by 79.

Going ahead to step 1:
2 divided by 79 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 79

Moving on to step 2:
79 can be fit into 21 0 times, resulting in a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Fetch the next digit (0) from the dividend, attach it to 21 and continue: 210 / 79

Let's proceed to step 3:
If we divide 210 by 79, we get 2 and a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 158 from 210, we get 52.
Take the next digit (0) from the dividend and append it to 52, then repeat: 520 / 79

Advancing to step 4:
79 can be fit into 520 6 times, resulting in a remainder of 46.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
Deduct 474 from 520 and we're left with 46.
Bring next digit (4) of the dividend behind the 46 and repeat the process: 464 / 79

Moving on to step 5:
79 can be fit into 464 5 times, resulting in a remainder of 69.
Record the quotient 5 as the next digit in the result. 
Result so far: 265.0
Subtract 395 from 464 to get 69.
Take the next digit (0) from the dividend and append it to 69, then repeat: 690 / 79

Step 6:
79 goes into 690 8 times with a remainder of 58.
Record the quotient 8 as the next digit in the result. 
Result so far: 2658.0
Deduct 632 from 690 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 7:
When dividing 580 by 79, we get 7 with a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 2658.7
Subtracting 553 from 580 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 8:
270 divided by 79 is 3 with a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 2658.73
If we take 237 away from 270, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 9:
330 divided by 79 is 4 with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 2658.734
The remainder is 14 after subtracting 316 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
When dividing 140 by 79, we get 1 with a remainder of 61.
The next digit of our result is 1. 
Result so far: 2658.7341
If we take 79 away from 140, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 11:
79 can be fit into 610 7 times, resulting in a remainder of 57.
Record the quotient 7 as the next digit in the result. 
Result so far: 2658.73417
Deduct 553 from 610 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 12:
If we divide 570 by 79, we get 7 and a remainder of 17.
The next digit of our result is 7. 
Result so far: 2658.734177
If we subtract 553 from 570, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

In conclusion, the division gives 2658.734177 with a balance of 1.7e-06.
