21098880 ÷ 673 
Let's see how many times 673 fits into 21098880.

Advancing to step 1:
673 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 673

On to step 2:
If we divide 21 by 673, we get 0 and a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 673

Step 3:
The number 673 fits into 210 0 times, leaving a remainder of 210.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 210, we end up with 210.
Grab the next digit (9) from the dividend, add it to 210, then carry on: 2109 / 673

Let's proceed to step 4:
2109 divided by 673 is 3 with a remainder of 90.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 90 after subtracting 2019 from 2109.
Append the next digit (8) from the dividend to 90 and continue with: 908 / 673

Let's proceed to step 5:
908 divided by 673 is 1 with a remainder of 235.
Write down 1 as next digit of the result. 
Result so far: 31.0
If we subtract 673 from 908, we get 235.
Include the next digit (8) from the dividend after 235, then repeat: 2358 / 673

Let's proceed to step 6:
When dividing 2358 by 673, we get 3 with a remainder of 339.
The number 3 becomes the next digit in our result. 
Result so far: 313.0
The remainder is 339 after subtracting 2019 from 2358.
Take the next digit (8) from the dividend and append it to 339, then repeat: 3398 / 673

Going ahead to step 7:
673 goes into 3398 5 times with a remainder of 33.
Write down 5 as next digit of the result. 
Result so far: 3135.0
Subtracting 3365 from 3398 leaves us with 33.
Grab the next digit (0) from the dividend, add it to 33, then carry on: 330 / 673

Advancing to step 8:
The number 673 fits into 330 0 times, leaving a remainder of 330.
The next digit of our result is 0. 
Result so far: 31350.0
If we subtract 0 from 330, we get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Step 9:
The number 673 fits into 3300 4 times, leaving a remainder of 608.
Put 4 as the next digit of the answer. 
Result so far: 31350.4
Subtracting 2692 from 3300 leaves us with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Going ahead to step 10:
6080 divided by 673 is 9 with a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 31350.49
Deduct 6057 from 6080 and we're left 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 673, we get 0 with a remainder of 230.
Put 0 as the next digit of the answer. 
Result so far: 31350.49
Subtract 0 from 230 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 12:
When dividing 2300 by 673, we get 3 with a remainder of 281.
Record the quotient 3 as the next digit in the result. 
Result so far: 31350.4903
The remainder is 281 after subtracting 2019 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Let's proceed to step 13:
The number 673 fits into 2810 4 times, leaving a remainder of 118.
Put 4 as the next digit of the answer. 
Result so far: 31350.49034
Subtract 2692 from 2810 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Moving on to step 14:
The number 673 fits into 1180 1 times, leaving a remainder of 507.
Record the quotient 1 as the next digit in the result. 
Result so far: 31350.490341
If we take 673 away from 1180, we end up with 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

Moving on to step 15:
If we divide 5070 by 673, we get 7 and a remainder of 359.
Use 7 as the next digit of our solution. 
Result so far: 31350.4903417
Deduct 4711 from 5070 and we're left with 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Step 16:
If we divide 3590 by 673, we get 5 and a remainder of 225.
Use 5 as the next digit of our solution. 
Result so far: 31350.49034175
The remainder is 225 after subtracting 3365 from 3590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

In conclusion, the division gives 31350.49034175 with a balance of 2.25e-07.
