We look at the division of 89542054 by 859 
We want to divide 89542054 by 859.

On to step 1:
8 divided by 859 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 859

Advancing to step 2:
859 can be fit into 89 0 times, resulting in a remainder of 89.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 89 and we're left with 89.
Include the next digit (5) from the dividend after 89, then repeat: 895 / 859

Moving on to step 3:
859 goes into 895 1 times with a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 859 away from 895, we end up with 36.
Fetch the next digit (4) from the dividend, attach it to 36 and continue: 364 / 859

Moving on to step 4:
When dividing 364 by 859, we get 0 with a remainder of 364.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 364 and we're left with 364.
Grab the next digit (2) from the dividend, add it to 364, then carry on: 3642 / 859

Let's proceed to step 5:
When dividing 3642 by 859, we get 4 with a remainder of 206.
Write down 4 as next digit of the result. 
Result so far: 104.0
The remainder is 206 after subtracting 3436 from 3642.
Append the next digit (0) from the dividend to 206 and continue with: 2060 / 859

Step 6:
When dividing 2060 by 859, we get 2 with a remainder of 342.
Use 2 as the next digit of our solution. 
Result so far: 1042.0
Deduct 1718 from 2060 and we're left with 342.
Include the next digit (5) from the dividend after 342, then repeat: 3425 / 859

Let's proceed to step 7:
859 can be fit into 3425 3 times, resulting in a remainder of 848.
The next digit of our result is 3. 
Result so far: 10423.0
The remainder is 848 after subtracting 2577 from 3425.
Fetch the next digit (4) from the dividend, attach it to 848 and continue: 8484 / 859

Let's proceed to step 8:
859 goes into 8484 9 times with a remainder of 753.
The number 9 becomes the next digit in our result. 
Result so far: 104239.0
If we subtract 7731 from 8484, we get 753.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7530, and continue the process.

On to step 9:
If we divide 7530 by 859, we get 8 and a remainder of 658.
The next digit of our result is 8. 
Result so far: 104239.8
Subtract 6872 from 7530 to get 658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

Moving on to step 10:
859 goes into 6580 7 times with a remainder of 567.
The number 7 becomes the next digit in our result. 
Result so far: 104239.87
Deduct 6013 from 6580 and we're left with 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

Going ahead to step 11:
The number 859 fits into 5670 6 times, leaving a remainder of 516.
Put 6 as the next digit of the answer. 
Result so far: 104239.876
The remainder is 516 after subtracting 5154 from 5670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Going ahead to step 12:
5160 divided by 859 is 6 with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 104239.8766
If we subtract 5154 from 5160, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 104239.8766, with a leftover of 6e-05.
