We divide 13333139 by 858
Our goal is to divide 13333139 by 858.

Moving on to step 1:
When dividing 1 by 858, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 858

Step 2:
858 can be fit into 13 0 times, resulting in a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 858

On to step 3:
858 can be fit into 133 0 times, resulting in a remainder of 133.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 133 after subtracting 0 from 133.
Take the next digit (3) from the dividend and append it to 133, then repeat: 1333 / 858

Advancing to step 4:
If we divide 1333 by 858, we get 1 and a remainder of 475.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 475 after subtracting 858 from 1333.
Include the next digit (3) from the dividend after 475, then repeat: 4753 / 858

Going ahead to step 5:
When dividing 4753 by 858, we get 5 with a remainder of 463.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 4290 from 4753 and we're left with 463.
Append the next digit (1) from the dividend to 463 and continue with: 4631 / 858

Advancing to step 6:
858 goes into 4631 5 times with a remainder of 341.
The number 5 becomes the next digit in our result. 
Result so far: 155.0
Subtract 4290 from 4631 to get 341.
Grab the next digit (3) from the dividend, add it to 341, then carry on: 3413 / 858

Advancing to step 7:
3413 divided by 858 is 3 with a remainder of 839.
Record the quotient 3 as the next digit in the result. 
Result so far: 1553.0
The remainder is 839 after subtracting 2574 from 3413.
Append the next digit (9) from the dividend to 839 and continue with: 8399 / 858

Let's proceed to step 8:
858 goes into 8399 9 times with a remainder of 677.
Use 9 as the next digit of our solution. 
Result so far: 15539.0
If we subtract 7722 from 8399, we get 677.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6770, and continue the process.

Let's proceed to step 9:
When dividing 6770 by 858, we get 7 with a remainder of 764.
Write down 7 as next digit of the result. 
Result so far: 15539.7
The remainder is 764 after subtracting 6006 from 6770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7640, and continue the process.

Advancing to step 10:
The number 858 fits into 7640 8 times, leaving a remainder of 776.
Record the quotient 8 as the next digit in the result. 
Result so far: 15539.78
Deduct 6864 from 7640 and we're left with 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

Going ahead to step 11:
7760 divided by 858 is 9 with a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 15539.789
Subtracting 7722 from 7760 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 12:
If we divide 380 by 858, we get 0 and a remainder of 380.
Write down 0 as next digit of the result. 
Result so far: 15539.789
If we subtract 0 from 380, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 13:
858 goes into 3800 4 times with a remainder of 368.
Write down 4 as next digit of the result. 
Result so far: 15539.78904
Deduct 3432 from 3800 and we're left with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

On to step 14:
858 goes into 3680 4 times with a remainder of 248.
Write down 4 as next digit of the result. 
Result so far: 15539.789044
Subtract 3432 from 3680 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

The final outcome is 15539.789044, with a leftover of 2.48e-05.
