900359 ÷ 86 
Our goal is to divide 900359 by 86.

Moving on to step 1:
When dividing 9 by 86, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 86

Advancing to step 2:
86 goes into 90 1 times with a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 86 from 90 to get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 86

Let's proceed to step 3:
86 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 40 and we're left with 40.
Grab the next digit (3) from the dividend, add it to 40, then carry on: 403 / 86

Let's proceed to step 4:
The number 86 fits into 403 4 times, leaving a remainder of 59.
Put 4 as the next digit of the answer. 
Result so far: 104.0
The remainder is 59 after subtracting 344 from 403.
Take the next digit (5) from the dividend and append it to 59, then repeat: 595 / 86

Moving on to step 5:
86 can be fit into 595 6 times, resulting in a remainder of 79.
The next digit of our result is 6. 
Result so far: 1046.0
Subtracting 516 from 595 leaves us with 79.
Grab the next digit (9) from the dividend, add it to 79, then carry on: 799 / 86

Let's proceed to step 6:
86 goes into 799 9 times with a remainder of 25.
The next digit of our result is 9. 
Result so far: 10469.0
If we subtract 774 from 799, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 7:
86 goes into 250 2 times with a remainder of 78.
The next digit of our result is 2. 
Result so far: 10469.2
Subtract 172 from 250 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 8:
When dividing 780 by 86, we get 9 with a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 10469.29
The remainder is 6 after subtracting 774 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 9:
86 can be fit into 60 0 times, resulting in a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 10469.29
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
When dividing 600 by 86, we get 6 with a remainder of 84.
Use 6 as the next digit of our solution. 
Result so far: 10469.2906
If we subtract 516 from 600, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 11:
When dividing 840 by 86, we get 9 with a remainder of 66.
The number 9 becomes the next digit in our result. 
Result so far: 10469.29069
If we take 774 away from 840, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 12:
When dividing 660 by 86, we get 7 with a remainder of 58.
Put 7 as the next digit of the answer. 
Result so far: 10469.290697
If we take 602 away from 660, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 13:
86 goes into 580 6 times with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 10469.2906976
If we subtract 516 from 580, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 14:
86 goes into 640 7 times with a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 10469.29069767
If we subtract 602 from 640, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

In conclusion, the division gives 10469.29069767 with a balance of 3.8e-08.
