Let's divide 26519891 by 858
We want to figure out the number of times 26519891 can be divided by 858.

Going ahead to step 1:
858 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 858

Moving on to step 2:
If we divide 26 by 858, we get 0 and a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 26, we get 26.
Grab the next digit (5) from the dividend, add it to 26, then carry on: 265 / 858

Advancing to step 3:
If we divide 265 by 858, we get 0 and a remainder of 265.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 265, we end up with 265.
Take the next digit (1) from the dividend and append it to 265, then repeat: 2651 / 858

Advancing to step 4:
If we divide 2651 by 858, we get 3 and a remainder of 77.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 2574 from 2651, we get 77.
Grab the next digit (9) from the dividend, add it to 77, then carry on: 779 / 858

Step 5:
When dividing 779 by 858, we get 0 with a remainder of 779.
Write down 0 as next digit of the result. 
Result so far: 30.0
Subtract 0 from 779 to get 779.
Fetch the next digit (8) from the dividend, attach it to 779 and continue: 7798 / 858

Moving on to step 6:
When dividing 7798 by 858, we get 9 with a remainder of 76.
Record the quotient 9 as the next digit in the result. 
Result so far: 309.0
The remainder is 76 after subtracting 7722 from 7798.
Grab the next digit (9) from the dividend, add it to 76, then carry on: 769 / 858

Advancing to step 7:
769 divided by 858 is 0 with a remainder of 769.
Record the quotient 0 as the next digit in the result. 
Result so far: 3090.0
If we subtract 0 from 769, we get 769.
Take the next digit (1) from the dividend and append it to 769, then repeat: 7691 / 858

Going ahead to step 8:
858 can be fit into 7691 8 times, resulting in a remainder of 827.
Record the quotient 8 as the next digit in the result. 
Result so far: 30908.0
If we take 6864 away from 7691, we end up with 827.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8270, and continue the process.

On to step 9:
If we divide 8270 by 858, we get 9 and a remainder of 548.
The next digit of our result is 9. 
Result so far: 30908.9
The remainder is 548 after subtracting 7722 from 8270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Advancing to step 10:
The number 858 fits into 5480 6 times, leaving a remainder of 332.
Use 6 as the next digit of our solution. 
Result so far: 30908.96
Subtracting 5148 from 5480 leaves us with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Advancing to step 11:
858 can be fit into 3320 3 times, resulting in a remainder of 746.
Record the quotient 3 as the next digit in the result. 
Result so far: 30908.963
The remainder is 746 after subtracting 2574 from 3320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7460, and continue the process.

Let's proceed to step 12:
If we divide 7460 by 858, we get 8 and a remainder of 596.
Record the quotient 8 as the next digit in the result. 
Result so far: 30908.9638
Subtract 6864 from 7460 to get 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Step 13:
The number 858 fits into 5960 6 times, leaving a remainder of 812.
Use 6 as the next digit of our solution. 
Result so far: 30908.96386
If we take 5148 away from 5960, we end up with 812.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8120, and continue the process.

Step 14:
When dividing 8120 by 858, we get 9 with a remainder of 398.
The next digit of our result is 9. 
Result so far: 30908.963869
Subtracting 7722 from 8120 leaves us with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Step 15:
When dividing 3980 by 858, we get 4 with a remainder of 548.
The number 4 becomes the next digit in our result. 
Result so far: 30908.9638694
Subtract 3432 from 3980 to get 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Moving on to step 16:
The number 858 fits into 5480 6 times, leaving a remainder of 332.
Record the quotient 6 as the next digit in the result. 
Result so far: 30908.96386946
If we take 5148 away from 5480, we end up with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

The final outcome is 30908.96386946, with a leftover of 3.32e-07.
