Let's divide 5987449 by 858
Let's see how many times 858 fits into 5987449.

Going ahead to step 1:
858 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 858

Moving on to step 2:
The number 858 fits into 59 0 times, leaving a remainder of 59.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 59 leaves us with 59.
Take the next digit (8) from the dividend and append it to 59, then repeat: 598 / 858

Going ahead to step 3:
When dividing 598 by 858, we get 0 with a remainder of 598.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 598 leaves us with 598.
Grab the next digit (7) from the dividend, add it to 598, then carry on: 5987 / 858

Advancing to step 4:
If we divide 5987 by 858, we get 6 and a remainder of 839.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 5148 from 5987 to get 839.
Append the next digit (4) from the dividend to 839 and continue with: 8394 / 858

On to step 5:
858 can be fit into 8394 9 times, resulting in a remainder of 672.
Put 9 as the next digit of the answer. 
Result so far: 69.0
If we subtract 7722 from 8394, we get 672.
Include the next digit (4) from the dividend after 672, then repeat: 6724 / 858

Moving on to step 6:
6724 divided by 858 is 7 with a remainder of 718.
Put 7 as the next digit of the answer. 
Result so far: 697.0
Deduct 6006 from 6724 and we're left with 718.
Fetch the next digit (9) from the dividend, attach it to 718 and continue: 7189 / 858

Let's proceed to step 7:
7189 divided by 858 is 8 with a remainder of 325.
The next digit of our result is 8. 
Result so far: 6978.0
The remainder is 325 after subtracting 6864 from 7189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Moving on to step 8:
If we divide 3250 by 858, we get 3 and a remainder of 676.
Record the quotient 3 as the next digit in the result. 
Result so far: 6978.3
Subtract 2574 from 3250 to get 676.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6760, and continue the process.

Let's proceed to step 9:
If we divide 6760 by 858, we get 7 and a remainder of 754.
Use 7 as the next digit of our solution. 
Result so far: 6978.37
Subtract 6006 from 6760 to get 754.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7540, and continue the process.

Moving on to step 10:
7540 divided by 858 is 8 with a remainder of 676.
Write down 8 as next digit of the result. 
Result so far: 6978.378
Subtracting 6864 from 7540 leaves us with 676.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6760, and continue the process.

Let's proceed to step 11:
When dividing 6760 by 858, we get 7 with a remainder of 754.
Put 7 as the next digit of the answer. 
Result so far: 6978.3787
If we take 6006 away from 6760, we end up with 754.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7540, and continue the process.

Advancing to step 12:
The number 858 fits into 7540 8 times, leaving a remainder of 676.
Put 8 as the next digit of the answer. 
Result so far: 6978.37878
If we subtract 6864 from 7540, we get 676.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6760, and continue the process.

Let's proceed to step 13:
When dividing 6760 by 858, we get 7 with a remainder of 754.
Put 7 as the next digit of the answer. 
Result so far: 6978.378787
Subtract 6006 from 6760 to get 754.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7540, and continue the process.

On to step 14:
If we divide 7540 by 858, we get 8 and a remainder of 676.
The next digit of our result is 8. 
Result so far: 6978.3787878
The remainder is 676 after subtracting 6864 from 7540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6760, and continue the process.

Step 15:
The number 858 fits into 6760 7 times, leaving a remainder of 754.
The number 7 becomes the next digit in our result. 
Result so far: 6978.37878787
If we take 6006 away from 6760, we end up with 754.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7540, and continue the process.

After the division, we end up with 6978.37878787 and a remainder of 7.54e-07.
