We're dividing 43128021 by 891 
We're looking to find how many times 891 goes into 43128021.

Advancing to step 1:
891 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 891

Going ahead to step 2:
The number 891 fits into 43 0 times, leaving a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Grab the next digit (1) from the dividend, add it to 43, then carry on: 431 / 891

On to step 3:
431 divided by 891 is 0 with a remainder of 431.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 431 and we're left with 431.
Grab the next digit (2) from the dividend, add it to 431, then carry on: 4312 / 891

Going ahead to step 4:
891 can be fit into 4312 4 times, resulting in a remainder of 748.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 3564 from 4312 leaves us with 748.
Bring next digit (8) of the dividend behind the 748 and repeat the process: 7488 / 891

Let's proceed to step 5:
891 goes into 7488 8 times with a remainder of 360.
Use 8 as the next digit of our solution. 
Result so far: 48.0
Deduct 7128 from 7488 and we're left with 360.
Bring next digit (0) of the dividend behind the 360 and repeat the process: 3600 / 891

Step 6:
891 goes into 3600 4 times with a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 484.0
If we subtract 3564 from 3600, we get 36.
Bring next digit (2) of the dividend behind the 36 and repeat the process: 362 / 891

Moving on to step 7:
891 can be fit into 362 0 times, resulting in a remainder of 362.
Record the quotient 0 as the next digit in the result. 
Result so far: 4840.0
The remainder is 362 after subtracting 0 from 362.
Include the next digit (1) from the dividend after 362, then repeat: 3621 / 891

Moving on to step 8:
If we divide 3621 by 891, we get 4 and a remainder of 57.
Put 4 as the next digit of the answer. 
Result so far: 48404.0
The remainder is 57 after subtracting 3564 from 3621.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 9:
When dividing 570 by 891, we get 0 with a remainder of 570.
Write down 0 as next digit of the result. 
Result so far: 48404.0
If we subtract 0 from 570, we get 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Advancing to step 10:
When dividing 5700 by 891, we get 6 with a remainder of 354.
Write down 6 as next digit of the result. 
Result so far: 48404.06
Subtracting 5346 from 5700 leaves us with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Moving on to step 11:
3540 divided by 891 is 3 with a remainder of 867.
The next digit of our result is 3. 
Result so far: 48404.063
Deduct 2673 from 3540 and we're left with 867.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8670, and continue the process.

Moving on to step 12:
When dividing 8670 by 891, we get 9 with a remainder of 651.
Write down 9 as next digit of the result. 
Result so far: 48404.0639
If we take 8019 away from 8670, we end up with 651.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6510, and continue the process.

Step 13:
When dividing 6510 by 891, we get 7 with a remainder of 273.
Write down 7 as next digit of the result. 
Result so far: 48404.06397
Subtracting 6237 from 6510 leaves us with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Let's proceed to step 14:
2730 divided by 891 is 3 with a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 48404.063973
Deduct 2673 from 2730 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 15:
When dividing 570 by 891, we get 0 with a remainder of 570.
Record the quotient 0 as the next digit in the result. 
Result so far: 48404.063973
The remainder is 570 after subtracting 0 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

On to step 16:
The number 891 fits into 5700 6 times, leaving a remainder of 354.
Write down 6 as next digit of the result. 
Result so far: 48404.06397306
If we take 5346 away from 5700, we end up with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

The quotient of the division is 48404.06397306, and the remainder is 3.54e-07.
