20643635 divided by 154 
We want to divide 20643635 by 154.

Going ahead to step 1:
The number 154 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 154

Moving on to step 2:
If we divide 20 by 154, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Append the next digit (6) from the dividend to 20 and continue with: 206 / 154

Moving on to step 3:
206 divided by 154 is 1 with a remainder of 52.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 154 from 206 to get 52.
Take the next digit (4) from the dividend and append it to 52, then repeat: 524 / 154

Step 4:
524 divided by 154 is 3 with a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 62 after subtracting 462 from 524.
Take the next digit (3) from the dividend and append it to 62, then repeat: 623 / 154

On to step 5:
When dividing 623 by 154, we get 4 with a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 134.0
Subtract 616 from 623 to get 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 154

On to step 6:
154 goes into 76 0 times with a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 1340.0
Subtracting 0 from 76 leaves us with 76.
Take the next digit (3) from the dividend and append it to 76, then repeat: 763 / 154

Let's proceed to step 7:
The number 154 fits into 763 4 times, leaving a remainder of 147.
Put 4 as the next digit of the answer. 
Result so far: 13404.0
The remainder is 147 after subtracting 616 from 763.
Fetch the next digit (5) from the dividend, attach it to 147 and continue: 1475 / 154

Step 8:
If we divide 1475 by 154, we get 9 and a remainder of 89.
Put 9 as the next digit of the answer. 
Result so far: 134049.0
If we subtract 1386 from 1475, we get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

On to step 9:
If we divide 890 by 154, we get 5 and a remainder of 120.
The next digit of our result is 5. 
Result so far: 134049.5
Subtract 770 from 890 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 10:
1200 divided by 154 is 7 with a remainder of 122.
Record the quotient 7 as the next digit in the result. 
Result so far: 134049.57
Subtracting 1078 from 1200 leaves us with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Moving on to step 11:
154 can be fit into 1220 7 times, resulting in a remainder of 142.
Use 7 as the next digit of our solution. 
Result so far: 134049.577
Subtracting 1078 from 1220 leaves us with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

The quotient of the division is 134049.577, and the remainder is 0.0142.
