We divide 21158886 by 440
Our goal is to divide 21158886 by 440.

Moving on to step 1:
440 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 440

Advancing to step 2:
If we divide 21 by 440, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Bring next digit (1) of the dividend behind the 21 and repeat the process: 211 / 440

Going ahead to step 3:
If we divide 211 by 440, we get 0 and a remainder of 211.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 211, we end up with 211.
Append the next digit (5) from the dividend to 211 and continue with: 2115 / 440

Advancing to step 4:
440 can be fit into 2115 4 times, resulting in a remainder of 355.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 1760 from 2115 and we're left with 355.
Append the next digit (8) from the dividend to 355 and continue with: 3558 / 440

Let's proceed to step 5:
3558 divided by 440 is 8 with a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 48.0
Subtracting 3520 from 3558 leaves us with 38.
Bring next digit (8) of the dividend behind the 38 and repeat the process: 388 / 440

Step 6:
When dividing 388 by 440, we get 0 with a remainder of 388.
Write down 0 as next digit of the result. 
Result so far: 480.0
Subtract 0 from 388 to get 388.
Take the next digit (8) from the dividend and append it to 388, then repeat: 3888 / 440

Moving on to step 7:
3888 divided by 440 is 8 with a remainder of 368.
Use 8 as the next digit of our solution. 
Result so far: 4808.0
If we subtract 3520 from 3888, we get 368.
Append the next digit (6) from the dividend to 368 and continue with: 3686 / 440

Going ahead to step 8:
If we divide 3686 by 440, we get 8 and a remainder of 166.
Write down 8 as next digit of the result. 
Result so far: 48088.0
If we subtract 3520 from 3686, we get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Advancing to step 9:
440 can be fit into 1660 3 times, resulting in a remainder of 340.
The number 3 becomes the next digit in our result. 
Result so far: 48088.3
Subtract 1320 from 1660 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 10:
440 can be fit into 3400 7 times, resulting in a remainder of 320.
Record the quotient 7 as the next digit in the result. 
Result so far: 48088.37
If we subtract 3080 from 3400, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 11:
440 goes into 3200 7 times with a remainder of 120.
The number 7 becomes the next digit in our result. 
Result so far: 48088.377
Subtract 3080 from 3200 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The final outcome is 48088.377, with a leftover of 0.012.
