We're dividing 21542155 by 76 
Let's see how many times 76 fits into 21542155.

On to step 1:
76 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 76

Going ahead to step 2:
76 goes into 21 0 times with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 76

Going ahead to step 3:
76 goes into 215 2 times with a remainder of 63.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 152 from 215 and we're left with 63.
Take the next digit (4) from the dividend and append it to 63, then repeat: 634 / 76

Advancing to step 4:
If we divide 634 by 76, we get 8 and a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
The remainder is 26 after subtracting 608 from 634.
Grab the next digit (2) from the dividend, add it to 26, then carry on: 262 / 76

Moving on to step 5:
If we divide 262 by 76, we get 3 and a remainder of 34.
The next digit of our result is 3. 
Result so far: 283.0
The remainder is 34 after subtracting 228 from 262.
Bring next digit (1) of the dividend behind the 34 and repeat the process: 341 / 76

Step 6:
341 divided by 76 is 4 with a remainder of 37.
Record the quotient 4 as the next digit in the result. 
Result so far: 2834.0
Deduct 304 from 341 and we're left with 37.
Bring next digit (5) of the dividend behind the 37 and repeat the process: 375 / 76

Going ahead to step 7:
When dividing 375 by 76, we get 4 with a remainder of 71.
Put 4 as the next digit of the answer. 
Result so far: 28344.0
Deduct 304 from 375 and we're left with 71.
Bring next digit (5) of the dividend behind the 71 and repeat the process: 715 / 76

Step 8:
If we divide 715 by 76, we get 9 and a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 283449.0
If we subtract 684 from 715, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 9:
76 can be fit into 310 4 times, resulting in a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 283449.4
If we take 304 away from 310, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
The number 76 fits into 60 0 times, leaving a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 283449.4
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 11:
76 goes into 600 7 times with a remainder of 68.
Put 7 as the next digit of the answer. 
Result so far: 283449.407
The remainder is 68 after subtracting 532 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 12:
76 goes into 680 8 times with a remainder of 72.
Use 8 as the next digit of our solution. 
Result so far: 283449.4078
Subtracting 608 from 680 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 13:
76 goes into 720 9 times with a remainder of 36.
Use 9 as the next digit of our solution. 
Result so far: 283449.40789
Deduct 684 from 720 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 14:
If we divide 360 by 76, we get 4 and a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 283449.407894
If we subtract 304 from 360, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 15:
The number 76 fits into 560 7 times, leaving a remainder of 28.
The number 7 becomes the next digit in our result. 
Result so far: 283449.4078947
The remainder is 28 after subtracting 532 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 16:
The number 76 fits into 280 3 times, leaving a remainder of 52.
Write down 3 as next digit of the result. 
Result so far: 283449.40789473
If we take 228 away from 280, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final outcome is 283449.40789473, with a leftover of 5.2e-08.
