We look at the division of 901289 by 86 
We're looking to find how many times 86 goes into 901289.

Let's proceed to step 1:
The number 86 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 86

Moving on to step 2:
If we divide 90 by 86, we get 1 and a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 4 after subtracting 86 from 90.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 86

Advancing to step 3:
The number 86 fits into 41 0 times, leaving a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 41, we get 41.
Fetch the next digit (2) from the dividend, attach it to 41 and continue: 412 / 86

Step 4:
When dividing 412 by 86, we get 4 with a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
The remainder is 68 after subtracting 344 from 412.
Append the next digit (8) from the dividend to 68 and continue with: 688 / 86

Moving on to step 5:
The number 86 fits into 688 8 times, leaving a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 1048.0
If we subtract 688 from 688, we get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 86

Advancing to step 6:
If we divide 9 by 86, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 10480.0
Subtracting 0 from 9 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
When dividing 90 by 86, we get 1 with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 10480.1
Subtract 86 from 90 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
The number 86 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 10480.1
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
86 can be fit into 400 4 times, resulting in a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 10480.104
Subtract 344 from 400 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 10:
86 can be fit into 560 6 times, resulting in a remainder of 44.
The next digit of our result is 6. 
Result so far: 10480.1046
Subtract 516 from 560 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 11:
86 goes into 440 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 10480.10465
If we subtract 430 from 440, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
The number 86 fits into 100 1 times, leaving a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 10480.104651
If we take 86 away from 100, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 13:
86 goes into 140 1 times with a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 10480.1046511
If we subtract 86 from 140, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

In conclusion, the division gives 10480.1046511 with a balance of 5.4e-07.
