We're dividing 20912087 by 654 
We're looking to find how many times 654 goes into 20912087.

Moving on to step 1:
2 divided by 654 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 654

Step 2:
The number 654 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Fetch the next digit (9) from the dividend, attach it to 20 and continue: 209 / 654

Moving on to step 3:
209 divided by 654 is 0 with a remainder of 209.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 209 leaves us with 209.
Grab the next digit (1) from the dividend, add it to 209, then carry on: 2091 / 654

Let's proceed to step 4:
The number 654 fits into 2091 3 times, leaving a remainder of 129.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 1962 from 2091 and we're left with 129.
Grab the next digit (2) from the dividend, add it to 129, then carry on: 1292 / 654

Advancing to step 5:
The number 654 fits into 1292 1 times, leaving a remainder of 638.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Subtracting 654 from 1292 leaves us with 638.
Fetch the next digit (0) from the dividend, attach it to 638 and continue: 6380 / 654

On to step 6:
6380 divided by 654 is 9 with a remainder of 494.
The next digit of our result is 9. 
Result so far: 319.0
If we subtract 5886 from 6380, we get 494.
Bring next digit (8) of the dividend behind the 494 and repeat the process: 4948 / 654

Advancing to step 7:
When dividing 4948 by 654, we get 7 with a remainder of 370.
The number 7 becomes the next digit in our result. 
Result so far: 3197.0
If we take 4578 away from 4948, we end up with 370.
Grab the next digit (7) from the dividend, add it to 370, then carry on: 3707 / 654

On to step 8:
The number 654 fits into 3707 5 times, leaving a remainder of 437.
Use 5 as the next digit of our solution. 
Result so far: 31975.0
The remainder is 437 after subtracting 3270 from 3707.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Going ahead to step 9:
654 goes into 4370 6 times with a remainder of 446.
Put 6 as the next digit of the answer. 
Result so far: 31975.6
Deduct 3924 from 4370 and we're left with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Step 10:
When dividing 4460 by 654, we get 6 with a remainder of 536.
The next digit of our result is 6. 
Result so far: 31975.66
Subtracting 3924 from 4460 leaves us with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

The final outcome is 31975.66, with a leftover of 0.536.
