21104630 ÷ 679 
Our goal is to divide 21104630 by 679.

Going ahead to step 1:
If we divide 2 by 679, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 679

Going ahead to step 2:
679 can be fit into 21 0 times, resulting in a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Fetch the next digit (1) from the dividend, attach it to 21 and continue: 211 / 679

Step 3:
211 divided by 679 is 0 with a remainder of 211.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 211, we get 211.
Include the next digit (0) from the dividend after 211, then repeat: 2110 / 679

Step 4:
The number 679 fits into 2110 3 times, leaving a remainder of 73.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 2037 away from 2110, we end up with 73.
Append the next digit (4) from the dividend to 73 and continue with: 734 / 679

Let's proceed to step 5:
The number 679 fits into 734 1 times, leaving a remainder of 55.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Deduct 679 from 734 and we're left with 55.
Append the next digit (6) from the dividend to 55 and continue with: 556 / 679

Step 6:
679 can be fit into 556 0 times, resulting in a remainder of 556.
Put 0 as the next digit of the answer. 
Result so far: 310.0
Subtract 0 from 556 to get 556.
Bring next digit (3) of the dividend behind the 556 and repeat the process: 5563 / 679

Going ahead to step 7:
5563 divided by 679 is 8 with a remainder of 131.
Write down 8 as next digit of the result. 
Result so far: 3108.0
Subtracting 5432 from 5563 leaves us with 131.
Include the next digit (0) from the dividend after 131, then repeat: 1310 / 679

Step 8:
679 goes into 1310 1 times with a remainder of 631.
Record the quotient 1 as the next digit in the result. 
Result so far: 31081.0
Subtract 679 from 1310 to get 631.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6310, and continue the process.

On to step 9:
679 goes into 6310 9 times with a remainder of 199.
Put 9 as the next digit of the answer. 
Result so far: 31081.9
Subtract 6111 from 6310 to get 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Moving on to step 10:
When dividing 1990 by 679, we get 2 with a remainder of 632.
Put 2 as the next digit of the answer. 
Result so far: 31081.92
If we take 1358 away from 1990, we end up with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Moving on to step 11:
679 can be fit into 6320 9 times, resulting in a remainder of 209.
The number 9 becomes the next digit in our result. 
Result so far: 31081.929
Subtract 6111 from 6320 to get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Advancing to step 12:
If we divide 2090 by 679, we get 3 and a remainder of 53.
Record the quotient 3 as the next digit in the result. 
Result so far: 31081.9293
Subtracting 2037 from 2090 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 13:
The number 679 fits into 530 0 times, leaving a remainder of 530.
The number 0 becomes the next digit in our result. 
Result so far: 31081.9293
Subtract 0 from 530 to get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

On to step 14:
If we divide 5300 by 679, we get 7 and a remainder of 547.
Record the quotient 7 as the next digit in the result. 
Result so far: 31081.929307
If we take 4753 away from 5300, we end up with 547.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5470, and continue the process.

On to step 15:
When dividing 5470 by 679, we get 8 with a remainder of 38.
Record the quotient 8 as the next digit in the result. 
Result so far: 31081.9293078
Deduct 5432 from 5470 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 16:
The number 679 fits into 380 0 times, leaving a remainder of 380.
Put 0 as the next digit of the answer. 
Result so far: 31081.9293078
If we subtract 0 from 380, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

In conclusion, the division gives 31081.9293078 with a balance of 3.8e-07.
