We're dividing 21405788 by 427 
Our goal is to divide 21405788 by 427.

Let's proceed to step 1:
427 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 427

Let's proceed to step 2:
427 goes into 21 0 times with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Append the next digit (4) from the dividend to 21 and continue with: 214 / 427

On to step 3:
If we divide 214 by 427, we get 0 and a remainder of 214.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 214 and we're left with 214.
Take the next digit (0) from the dividend and append it to 214, then repeat: 2140 / 427

Step 4:
If we divide 2140 by 427, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 2135 from 2140 to get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 427

Advancing to step 5:
When dividing 55 by 427, we get 0 with a remainder of 55.
The next digit of our result is 0. 
Result so far: 50.0
Deduct 0 from 55 and we're left with 55.
Fetch the next digit (7) from the dividend, attach it to 55 and continue: 557 / 427

Let's proceed to step 6:
The number 427 fits into 557 1 times, leaving a remainder of 130.
Write down 1 as next digit of the result. 
Result so far: 501.0
The remainder is 130 after subtracting 427 from 557.
Bring next digit (8) of the dividend behind the 130 and repeat the process: 1308 / 427

Advancing to step 7:
427 can be fit into 1308 3 times, resulting in a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 5013.0
Subtracting 1281 from 1308 leaves us with 27.
Fetch the next digit (8) from the dividend, attach it to 27 and continue: 278 / 427

Advancing to step 8:
When dividing 278 by 427, we get 0 with a remainder of 278.
The next digit of our result is 0. 
Result so far: 50130.0
The remainder is 278 after subtracting 0 from 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Step 9:
427 can be fit into 2780 6 times, resulting in a remainder of 218.
The number 6 becomes the next digit in our result. 
Result so far: 50130.6
Deduct 2562 from 2780 and we're left with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Going ahead to step 10:
If we divide 2180 by 427, we get 5 and a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 50130.65
Deduct 2135 from 2180 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 11:
427 can be fit into 450 1 times, resulting in a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 50130.651
Subtracting 427 from 450 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 12:
If we divide 230 by 427, we get 0 and a remainder of 230.
Record the quotient 0 as the next digit in the result. 
Result so far: 50130.651
If we take 0 away from 230, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 13:
When dividing 2300 by 427, we get 5 with a remainder of 165.
Use 5 as the next digit of our solution. 
Result so far: 50130.65105
Subtract 2135 from 2300 to get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

On to step 14:
1650 divided by 427 is 3 with a remainder of 369.
The next digit of our result is 3. 
Result so far: 50130.651053
If we subtract 1281 from 1650, we get 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Step 15:
If we divide 3690 by 427, we get 8 and a remainder of 274.
Use 8 as the next digit of our solution. 
Result so far: 50130.6510538
Deduct 3416 from 3690 and we're left with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Step 16:
The number 427 fits into 2740 6 times, leaving a remainder of 178.
Use 6 as the next digit of our solution. 
Result so far: 50130.65105386
Deduct 2562 from 2740 and we're left with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

The quotient of the division is 50130.65105386, and the remainder is 1.78e-07.
