We look at the division of 21568989 by 422 
Our goal is to divide 21568989 by 422.

Going ahead to step 1:
If we divide 2 by 422, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 422

Advancing to step 2:
422 goes into 21 0 times with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 422

Step 3:
If we divide 215 by 422, we get 0 and a remainder of 215.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 215 after subtracting 0 from 215.
Include the next digit (6) from the dividend after 215, then repeat: 2156 / 422

Let's proceed to step 4:
422 goes into 2156 5 times with a remainder of 46.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 2110 away from 2156, we end up with 46.
Bring next digit (8) of the dividend behind the 46 and repeat the process: 468 / 422

Moving on to step 5:
422 goes into 468 1 times with a remainder of 46.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
If we subtract 422 from 468, we get 46.
Include the next digit (9) from the dividend after 46, then repeat: 469 / 422

Advancing to step 6:
422 goes into 469 1 times with a remainder of 47.
Write down 1 as next digit of the result. 
Result so far: 511.0
Subtracting 422 from 469 leaves us with 47.
Append the next digit (8) from the dividend to 47 and continue with: 478 / 422

Let's proceed to step 7:
422 can be fit into 478 1 times, resulting in a remainder of 56.
Record the quotient 1 as the next digit in the result. 
Result so far: 5111.0
If we take 422 away from 478, we end up with 56.
Bring next digit (9) of the dividend behind the 56 and repeat the process: 569 / 422

Let's proceed to step 8:
422 can be fit into 569 1 times, resulting in a remainder of 147.
Write down 1 as next digit of the result. 
Result so far: 51111.0
Subtracting 422 from 569 leaves us with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Going ahead to step 9:
When dividing 1470 by 422, we get 3 with a remainder of 204.
Record the quotient 3 as the next digit in the result. 
Result so far: 51111.3
Deduct 1266 from 1470 and we're left with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Advancing to step 10:
When dividing 2040 by 422, we get 4 with a remainder of 352.
Put 4 as the next digit of the answer. 
Result so far: 51111.34
If we take 1688 away from 2040, we end up with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Step 11:
The number 422 fits into 3520 8 times, leaving a remainder of 144.
Put 8 as the next digit of the answer. 
Result so far: 51111.348
If we take 3376 away from 3520, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 12:
The number 422 fits into 1440 3 times, leaving a remainder of 174.
Put 3 as the next digit of the answer. 
Result so far: 51111.3483
If we subtract 1266 from 1440, we get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Let's proceed to step 13:
422 can be fit into 1740 4 times, resulting in a remainder of 52.
The number 4 becomes the next digit in our result. 
Result so far: 51111.34834
Subtracting 1688 from 1740 leaves us 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.

Going ahead to step 14:
The number 422 fits into 520 1 times, leaving a remainder of 98.
Use 1 as the next digit of our solution. 
Result so far: 51111.348341
The remainder is 98 after subtracting 422 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 15:
422 goes into 980 2 times with a remainder of 136.
Write down 2 as next digit of the result. 
Result so far: 51111.3483412
Deduct 844 from 980 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

On to step 16:
422 goes into 1360 3 times with a remainder of 94.
The number 3 becomes the next digit in our result. 
Result so far: 51111.34834123
If we subtract 1266 from 1360, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

The final outcome is 51111.34834123, with a leftover of 9.4e-08.
