42573964 divided by 891 
We're looking to find how many times 891 goes into 42573964.

Advancing to step 1:
If we divide 4 by 891, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 891

Moving on to step 2:
When dividing 42 by 891, we get 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Fetch the next digit (5) from the dividend, attach it to 42 and continue: 425 / 891

Advancing to step 3:
When dividing 425 by 891, we get 0 with a remainder of 425.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 425 and we're left with 425.
Bring next digit (7) of the dividend behind the 425 and repeat the process: 4257 / 891

Advancing to step 4:
When dividing 4257 by 891, we get 4 with a remainder of 693.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 3564 from 4257 to get 693.
Include the next digit (3) from the dividend after 693, then repeat: 6933 / 891

Step 5:
If we divide 6933 by 891, we get 7 and a remainder of 696.
Write down 7 as next digit of the result. 
Result so far: 47.0
If we take 6237 away from 6933, we end up with 696.
Append the next digit (9) from the dividend to 696 and continue with: 6969 / 891

Moving on to step 6:
891 can be fit into 6969 7 times, resulting in a remainder of 732.
Use 7 as the next digit of our solution. 
Result so far: 477.0
Subtract 6237 from 6969 to get 732.
Include the next digit (6) from the dividend after 732, then repeat: 7326 / 891

Going ahead to step 7:
891 can be fit into 7326 8 times, resulting in a remainder of 198.
Use 8 as the next digit of our solution. 
Result so far: 4778.0
The remainder is 198 after subtracting 7128 from 7326.
Append the next digit (4) from the dividend to 198 and continue with: 1984 / 891

Advancing to step 8:
When dividing 1984 by 891, we get 2 with a remainder of 202.
The next digit of our result is 2. 
Result so far: 47782.0
If we subtract 1782 from 1984, we get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Let's proceed to step 9:
If we divide 2020 by 891, we get 2 and a remainder of 238.
Put 2 as the next digit of the answer. 
Result so far: 47782.2
If we subtract 1782 from 2020, we get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Let's proceed to step 10:
If we divide 2380 by 891, we get 2 and a remainder of 598.
Write down 2 as next digit of the result. 
Result so far: 47782.22
If we take 1782 away from 2380, we end up with 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

After the division, we end up with 47782.22 and a remainder of 0.598.
