We're dividing 20491978 by 989 
Our goal is to divide 20491978 by 989.

Moving on to step 1:
989 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 989

Advancing to step 2:
989 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Include the next digit (4) from the dividend after 20, then repeat: 204 / 989

Let's proceed to step 3:
989 goes into 204 0 times with a remainder of 204.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 204 and we're left with 204.
Append the next digit (9) from the dividend to 204 and continue with: 2049 / 989

Advancing to step 4:
989 can be fit into 2049 2 times, resulting in a remainder of 71.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 1978 away from 2049, we end up with 71.
Bring next digit (1) of the dividend behind the 71 and repeat the process: 711 / 989

Moving on to step 5:
If we divide 711 by 989, we get 0 and a remainder of 711.
Write down 0 as next digit of the result. 
Result so far: 20.0
The remainder is 711 after subtracting 0 from 711.
Take the next digit (9) from the dividend and append it to 711, then repeat: 7119 / 989

Advancing to step 6:
989 goes into 7119 7 times with a remainder of 196.
The number 7 becomes the next digit in our result. 
Result so far: 207.0
Subtracting 6923 from 7119 leaves us with 196.
Include the next digit (7) from the dividend after 196, then repeat: 1967 / 989

Step 7:
989 can be fit into 1967 1 times, resulting in a remainder of 978.
Record the quotient 1 as the next digit in the result. 
Result so far: 2071.0
If we subtract 989 from 1967, we get 978.
Include the next digit (8) from the dividend after 978, then repeat: 9788 / 989

Advancing to step 8:
9788 divided by 989 is 9 with a remainder of 887.
Record the quotient 9 as the next digit in the result. 
Result so far: 20719.0
Subtracting 8901 from 9788 leaves us with 887.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8870, and continue the process.

Step 9:
When dividing 8870 by 989, we get 8 with a remainder of 958.
Put 8 as the next digit of the answer. 
Result so far: 20719.8
If we take 7912 away from 8870, we end up with 958.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9580, and continue the process.

Step 10:
989 can be fit into 9580 9 times, resulting in a remainder of 679.
Put 9 as the next digit of the answer. 
Result so far: 20719.89
The remainder is 679 after subtracting 8901 from 9580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6790, and continue the process.

On to step 11:
989 can be fit into 6790 6 times, resulting in a remainder of 856.
The next digit of our result is 6. 
Result so far: 20719.896
If we subtract 5934 from 6790, we get 856.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8560, and continue the process.

Step 12:
If we divide 8560 by 989, we get 8 and a remainder of 648.
Use 8 as the next digit of our solution. 
Result so far: 20719.8968
The remainder is 648 after subtracting 7912 from 8560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Advancing to step 13:
989 can be fit into 6480 6 times, resulting in a remainder of 546.
The next digit of our result is 6. 
Result so far: 20719.89686
The remainder is 546 after subtracting 5934 from 6480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Moving on to step 14:
If we divide 5460 by 989, we get 5 and a remainder of 515.
Record the quotient 5 as the next digit in the result. 
Result so far: 20719.896865
The remainder is 515 after subtracting 4945 from 5460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Step 15:
If we divide 5150 by 989, we get 5 and a remainder of 205.
Put 5 as the next digit of the answer. 
Result so far: 20719.8968655
Subtracting 4945 from 5150 leaves us with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

The quotient of the division is 20719.8968655, and the remainder is 2.05e-06.
