20789109 divided by 154 
Let's see how many times 154 fits into 20789109.

Step 1:
2 divided by 154 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 154

Advancing to step 2:
154 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Append the next digit (7) from the dividend to 20 and continue with: 207 / 154

On to step 3:
If we divide 207 by 154, we get 1 and a remainder of 53.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 154 from 207, we get 53.
Bring next digit (8) of the dividend behind the 53 and repeat the process: 538 / 154

Advancing to step 4:
The number 154 fits into 538 3 times, leaving a remainder of 76.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Deduct 462 from 538 and we're left with 76.
Grab the next digit (9) from the dividend, add it to 76, then carry on: 769 / 154

Moving on to step 5:
The number 154 fits into 769 4 times, leaving a remainder of 153.
Use 4 as the next digit of our solution. 
Result so far: 134.0
If we subtract 616 from 769, we get 153.
Append the next digit (1) from the dividend to 153 and continue with: 1531 / 154

Going ahead to step 6:
1531 divided by 154 is 9 with a remainder of 145.
The next digit of our result is 9. 
Result so far: 1349.0
The remainder is 145 after subtracting 1386 from 1531.
Include the next digit (0) from the dividend after 145, then repeat: 1450 / 154

Moving on to step 7:
If we divide 1450 by 154, we get 9 and a remainder of 64.
Write down 9 as next digit of the result. 
Result so far: 13499.0
The remainder is 64 after subtracting 1386 from 1450.
Fetch the next digit (9) from the dividend, attach it to 64 and continue: 649 / 154

Step 8:
The number 154 fits into 649 4 times, leaving a remainder of 33.
The next digit of our result is 4. 
Result so far: 134994.0
Subtract 616 from 649 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 9:
154 can be fit into 330 2 times, resulting in a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 134994.2
Subtracting 308 from 330 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 10:
220 divided by 154 is 1 with a remainder of 66.
The next digit of our result is 1. 
Result so far: 134994.21
Deduct 154 from 220 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 11:
154 can be fit into 660 4 times, resulting in a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 134994.214
Subtract 616 from 660 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 12:
154 can be fit into 440 2 times, resulting in a remainder of 132.
The next digit of our result is 2. 
Result so far: 134994.2142
If we take 308 away from 440, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 13:
154 can be fit into 1320 8 times, resulting in a remainder of 88.
Write down 8 as next digit of the result. 
Result so far: 134994.21428
Deduct 1232 from 1320 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 14:
The number 154 fits into 880 5 times, leaving a remainder of 110.
Use 5 as the next digit of our solution. 
Result so far: 134994.214285
The remainder is 110 after subtracting 770 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 15:
The number 154 fits into 1100 7 times, leaving a remainder of 22.
Put 7 as the next digit of the answer. 
Result so far: 134994.2142857
Subtracting 1078 from 1100 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 16:
When dividing 220 by 154, we get 1 with a remainder of 66.
Write down 1 as next digit of the result. 
Result so far: 134994.21428571
If we subtract 154 from 220, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

After the division, we end up with 134994.21428571 and a remainder of 6.6e-08.
