We divide 784409 by 86
Our goal is to divide 784409 by 86.

Let's proceed to step 1:
7 divided by 86 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 86

Going ahead to step 2:
When dividing 78 by 86, we get 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Fetch the next digit (4) from the dividend, attach it to 78 and continue: 784 / 86

Advancing to step 3:
If we divide 784 by 86, we get 9 and a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 774 from 784 to get 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 86

Advancing to step 4:
86 goes into 104 1 times with a remainder of 18.
The next digit of our result is 1. 
Result so far: 91.0
If we subtract 86 from 104, we get 18.
Take the next digit (0) from the dividend and append it to 18, then repeat: 180 / 86

Moving on to step 5:
86 can be fit into 180 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 912.0
If we take 172 away from 180, we end up with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 86

On to step 6:
86 goes into 89 1 times with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 9121.0
If we subtract 86 from 89, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
When dividing 30 by 86, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 9121.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
86 can be fit into 300 3 times, resulting in a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 9121.03
The remainder is 42 after subtracting 258 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 9:
420 divided by 86 is 4 with a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 9121.034
If we subtract 344 from 420, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 10:
If we divide 760 by 86, we get 8 and a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 9121.0348
Deduct 688 from 760 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 11:
720 divided by 86 is 8 with a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 9121.03488
Deduct 688 from 720 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 9121.03488, with a leftover of 3.2e-05.
