42278144 divided by 891 
We want to divide 42278144 by 891.

Moving on to step 1:
891 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 891

Moving on to step 2:
891 can be fit into 42 0 times, resulting in a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Take the next digit (2) from the dividend and append it to 42, then repeat: 422 / 891

Going ahead to step 3:
422 divided by 891 is 0 with a remainder of 422.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 422 and we're left with 422.
Grab the next digit (7) from the dividend, add it to 422, then carry on: 4227 / 891

Let's proceed to step 4:
891 can be fit into 4227 4 times, resulting in a remainder of 663.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 663 after subtracting 3564 from 4227.
Take the next digit (8) from the dividend and append it to 663, then repeat: 6638 / 891

Going ahead to step 5:
891 goes into 6638 7 times with a remainder of 401.
Put 7 as the next digit of the answer. 
Result so far: 47.0
Deduct 6237 from 6638 and we're left with 401.
Include the next digit (1) from the dividend after 401, then repeat: 4011 / 891

Advancing to step 6:
If we divide 4011 by 891, we get 4 and a remainder of 447.
The next digit of our result is 4. 
Result so far: 474.0
Deduct 3564 from 4011 and we're left with 447.
Append the next digit (4) from the dividend to 447 and continue with: 4474 / 891

On to step 7:
When dividing 4474 by 891, we get 5 with a remainder of 19.
Record the quotient 5 as the next digit in the result. 
Result so far: 4745.0
If we take 4455 away from 4474, we end up with 19.
Fetch the next digit (4) from the dividend, attach it to 19 and continue: 194 / 891

Going ahead to step 8:
194 divided by 891 is 0 with a remainder of 194.
The next digit of our result is 0. 
Result so far: 47450.0
Subtract 0 from 194 to get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Let's proceed to step 9:
891 can be fit into 1940 2 times, resulting in a remainder of 158.
The next digit of our result is 2. 
Result so far: 47450.2
Subtracting 1782 from 1940 leaves us 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.

Moving on to step 10:
1580 divided by 891 is 1 with a remainder of 689.
Write down 1 as next digit of the result. 
Result so far: 47450.21
If we take 891 away from 1580, we end up with 689.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6890, and continue the process.

Advancing to step 11:
When dividing 6890 by 891, we get 7 with a remainder of 653.
The next digit of our result is 7. 
Result so far: 47450.217
If we take 6237 away from 6890, we end up with 653.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6530, and continue the process.

Let's proceed to step 12:
When dividing 6530 by 891, we get 7 with a remainder of 293.
The next digit of our result is 7. 
Result so far: 47450.2177
If we subtract 6237 from 6530, we get 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

The final outcome is 47450.2177, with a leftover of 0.00293.
