We look at the division of 21612023 by 427 
We want to divide 21612023 by 427.

Going ahead to step 1:
If we divide 2 by 427, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
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 / 427

On to step 2:
21 divided by 427 is 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 427

Going ahead to step 3:
427 can be fit into 216 0 times, resulting in a remainder of 216.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 216 leaves us with 216.
Bring next digit (1) of the dividend behind the 216 and repeat the process: 2161 / 427

On to step 4:
If we divide 2161 by 427, we get 5 and a remainder of 26.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 2135 from 2161 leaves us with 26.
Grab the next digit (2) from the dividend, add it to 26, then carry on: 262 / 427

Let's proceed to step 5:
262 divided by 427 is 0 with a remainder of 262.
The next digit of our result is 0. 
Result so far: 50.0
Deduct 0 from 262 and we're left with 262.
Bring next digit (0) of the dividend behind the 262 and repeat the process: 2620 / 427

Moving on to step 6:
2620 divided by 427 is 6 with a remainder of 58.
Write down 6 as next digit of the result. 
Result so far: 506.0
Subtract 2562 from 2620 to get 58.
Append the next digit (2) from the dividend to 58 and continue with: 582 / 427

Going ahead to step 7:
582 divided by 427 is 1 with a remainder of 155.
The next digit of our result is 1. 
Result so far: 5061.0
Subtracting 427 from 582 leaves us with 155.
Include the next digit (3) from the dividend after 155, then repeat: 1553 / 427

On to step 8:
427 can be fit into 1553 3 times, resulting in a remainder of 272.
Write down 3 as next digit of the result. 
Result so far: 50613.0
Subtracting 1281 from 1553 leaves us with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Going ahead to step 9:
427 goes into 2720 6 times with a remainder of 158.
Put 6 as the next digit of the answer. 
Result so far: 50613.6
If we take 2562 away from 2720, we end up with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Let's proceed to step 10:
1580 divided by 427 is 3 with a remainder of 299.
Put 3 as the next digit of the answer. 
Result so far: 50613.63
Subtract 1281 from 1580 to get 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Moving on to step 11:
The number 427 fits into 2990 7 times, leaving a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 50613.637
Subtract 2989 from 2990 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 12:
If we divide 10 by 427, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 50613.637
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
The number 427 fits into 100 0 times, leaving a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 50613.637
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final outcome is 50613.637, with a leftover of 0.0001.
