20822590 ÷ 154 
Let's see how many times 154 fits into 20822590.

Going ahead to step 1:
The number 154 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 154

On to step 2:
When dividing 20 by 154, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 154

Step 3:
When dividing 208 by 154, we get 1 with a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 154 from 208 and we're left with 54.
Bring next digit (2) of the dividend behind the 54 and repeat the process: 542 / 154

On to step 4:
The number 154 fits into 542 3 times, leaving a remainder of 80.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we subtract 462 from 542, we get 80.
Grab the next digit (2) from the dividend, add it to 80, then carry on: 802 / 154

Going ahead to step 5:
The number 154 fits into 802 5 times, leaving a remainder of 32.
Use 5 as the next digit of our solution. 
Result so far: 135.0
Deduct 770 from 802 and we're left with 32.
Grab the next digit (5) from the dividend, add it to 32, then carry on: 325 / 154

On to step 6:
154 goes into 325 2 times with a remainder of 17.
The number 2 becomes the next digit in our result. 
Result so far: 1352.0
Subtracting 308 from 325 leaves us with 17.
Take the next digit (9) from the dividend and append it to 17, then repeat: 179 / 154

Advancing to step 7:
154 goes into 179 1 times with a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 13521.0
Subtracting 154 from 179 leaves us with 25.
Fetch the next digit (0) from the dividend, attach it to 25 and continue: 250 / 154

Moving on to step 8:
250 divided by 154 is 1 with a remainder of 96.
Put 1 as the next digit of the answer. 
Result so far: 135211.0
If we take 154 away from 250, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 9:
When dividing 960 by 154, we get 6 with a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 135211.6
The remainder is 36 after subtracting 924 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 10:
When dividing 360 by 154, we get 2 with a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 135211.62
The remainder is 52 after subtracting 308 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 11:
154 goes into 520 3 times with a remainder of 58.
Record the quotient 3 as the next digit in the result. 
Result so far: 135211.623
The remainder is 58 after subtracting 462 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 12:
154 goes into 580 3 times with a remainder of 118.
Write down 3 as next digit of the result. 
Result so far: 135211.6233
If we take 462 away from 580, we end up with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

After the division, we end up with 135211.6233 and a remainder of 0.00118.
