We look at the division of 20505950 by 189 
Let's see how many times 189 fits into 20505950.

Advancing to step 1:
189 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 189

Going ahead to step 2:
The number 189 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Fetch the next digit (5) from the dividend, attach it to 20 and continue: 205 / 189

Going ahead to step 3:
If we divide 205 by 189, we get 1 and a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 189 from 205 and we're left with 16.
Append the next digit (0) from the dividend to 16 and continue with: 160 / 189

Step 4:
The number 189 fits into 160 0 times, leaving a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 160 to get 160.
Grab the next digit (5) from the dividend, add it to 160, then carry on: 1605 / 189

Let's proceed to step 5:
If we divide 1605 by 189, we get 8 and a remainder of 93.
Record the quotient 8 as the next digit in the result. 
Result so far: 108.0
Deduct 1512 from 1605 and we're left with 93.
Fetch the next digit (9) from the dividend, attach it to 93 and continue: 939 / 189

Going ahead to step 6:
When dividing 939 by 189, we get 4 with a remainder of 183.
The next digit of our result is 4. 
Result so far: 1084.0
The remainder is 183 after subtracting 756 from 939.
Append the next digit (5) from the dividend to 183 and continue with: 1835 / 189

Step 7:
1835 divided by 189 is 9 with a remainder of 134.
The next digit of our result is 9. 
Result so far: 10849.0
If we take 1701 away from 1835, we end up with 134.
Grab the next digit (0) from the dividend, add it to 134, then carry on: 1340 / 189

Advancing to step 8:
If we divide 1340 by 189, we get 7 and a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 108497.0
If we subtract 1323 from 1340, 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.

Moving on to step 9:
If we divide 170 by 189, we get 0 and a remainder of 170.
Use 0 as the next digit of our solution. 
Result so far: 108497.0
If we take 0 away from 170, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 10:
If we divide 1700 by 189, we get 8 and a remainder of 188.
Write down 8 as next digit of the result. 
Result so far: 108497.08
Deduct 1512 from 1700 and we're left with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Step 11:
189 can be fit into 1880 9 times, resulting in a remainder of 179.
The next digit of our result is 9. 
Result so far: 108497.089
Subtracting 1701 from 1880 leaves us with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Advancing to step 12:
1790 divided by 189 is 9 with a remainder of 89.
Record the quotient 9 as the next digit in the result. 
Result so far: 108497.0899
The remainder is 89 after subtracting 1701 from 1790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

The final result is 108497.0899 with a remainder of 0.00089.
