Let's divide 44891987 by 858
Let's see how many times 858 fits into 44891987.

On to step 1:
When dividing 4 by 858, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 858

Step 2:
858 can be fit into 44 0 times, resulting in a remainder of 44.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 44 to get 44.
Fetch the next digit (8) from the dividend, attach it to 44 and continue: 448 / 858

Let's proceed to step 3:
If we divide 448 by 858, we get 0 and a remainder of 448.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 448 and we're left with 448.
Include the next digit (9) from the dividend after 448, then repeat: 4489 / 858

Step 4:
The number 858 fits into 4489 5 times, leaving a remainder of 199.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 4290 from 4489, we get 199.
Take the next digit (1) from the dividend and append it to 199, then repeat: 1991 / 858

On to step 5:
858 goes into 1991 2 times with a remainder of 275.
Write down 2 as next digit of the result. 
Result so far: 52.0
Subtract 1716 from 1991 to get 275.
Fetch the next digit (9) from the dividend, attach it to 275 and continue: 2759 / 858

Let's proceed to step 6:
858 can be fit into 2759 3 times, resulting in a remainder of 185.
Use 3 as the next digit of our solution. 
Result so far: 523.0
If we subtract 2574 from 2759, we get 185.
Fetch the next digit (8) from the dividend, attach it to 185 and continue: 1858 / 858

Step 7:
If we divide 1858 by 858, we get 2 and a remainder of 142.
Put 2 as the next digit of the answer. 
Result so far: 5232.0
If we take 1716 away from 1858, we end up with 142.
Append the next digit (7) from the dividend to 142 and continue with: 1427 / 858

On to step 8:
If we divide 1427 by 858, we get 1 and a remainder of 569.
The next digit of our result is 1. 
Result so far: 52321.0
Subtracting 858 from 1427 leaves us with 569.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5690, and continue the process.

Moving on to step 9:
The number 858 fits into 5690 6 times, leaving a remainder of 542.
Write down 6 as next digit of the result. 
Result so far: 52321.6
If we take 5148 away from 5690, we end up with 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Advancing to step 10:
858 goes into 5420 6 times with a remainder of 272.
Write down 6 as next digit of the result. 
Result so far: 52321.66
The remainder is 272 after subtracting 5148 from 5420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

After the division, we end up with 52321.66 and a remainder of 0.272.
