We're dividing 80390341 by 864 
We want to divide 80390341 by 864.

Advancing to step 1:
8 divided by 864 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 864

Advancing to step 2:
80 divided by 864 is 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Append the next digit (3) from the dividend to 80 and continue with: 803 / 864

Step 3:
When dividing 803 by 864, we get 0 with a remainder of 803.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 803 after subtracting 0 from 803.
Grab the next digit (9) from the dividend, add it to 803, then carry on: 8039 / 864

Step 4:
If we divide 8039 by 864, we get 9 and a remainder of 263.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 7776 from 8039 to get 263.
Fetch the next digit (0) from the dividend, attach it to 263 and continue: 2630 / 864

Let's proceed to step 5:
When dividing 2630 by 864, we get 3 with a remainder of 38.
Record the quotient 3 as the next digit in the result. 
Result so far: 93.0
If we take 2592 away from 2630, we end up with 38.
Bring next digit (3) of the dividend behind the 38 and repeat the process: 383 / 864

On to step 6:
When dividing 383 by 864, we get 0 with a remainder of 383.
The next digit of our result is 0. 
Result so far: 930.0
If we take 0 away from 383, we end up with 383.
Append the next digit (4) from the dividend to 383 and continue with: 3834 / 864

Let's proceed to step 7:
When dividing 3834 by 864, we get 4 with a remainder of 378.
Use 4 as the next digit of our solution. 
Result so far: 9304.0
If we take 3456 away from 3834, we end up with 378.
Fetch the next digit (1) from the dividend, attach it to 378 and continue: 3781 / 864

Step 8:
When dividing 3781 by 864, we get 4 with a remainder of 325.
The number 4 becomes the next digit in our result. 
Result so far: 93044.0
Subtract 3456 from 3781 to get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Moving on to step 9:
864 can be fit into 3250 3 times, resulting in a remainder of 658.
Record the quotient 3 as the next digit in the result. 
Result so far: 93044.3
The remainder is 658 after subtracting 2592 from 3250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

Going ahead to step 10:
864 can be fit into 6580 7 times, resulting in a remainder of 532.
Put 7 as the next digit of the answer. 
Result so far: 93044.37
Subtract 6048 from 6580 to get 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Moving on to step 11:
864 can be fit into 5320 6 times, resulting in a remainder of 136.
Put 6 as the next digit of the answer. 
Result so far: 93044.376
Subtract 5184 from 5320 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Moving on to step 12:
864 goes into 1360 1 times with a remainder of 496.
Put 1 as the next digit of the answer. 
Result so far: 93044.3761
Deduct 864 from 1360 and we're left with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Moving on to step 13:
864 can be fit into 4960 5 times, resulting in a remainder of 640.
The next digit of our result is 5. 
Result so far: 93044.37615
Subtracting 4320 from 4960 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 14:
6400 divided by 864 is 7 with a remainder of 352.
Put 7 as the next digit of the answer. 
Result so far: 93044.376157
Subtract 6048 from 6400 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Step 15:
3520 divided by 864 is 4 with a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 93044.3761574
Deduct 3456 from 3520 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 16:
When dividing 640 by 864, we get 0 with a remainder of 640.
Record the quotient 0 as the next digit in the result. 
Result so far: 93044.3761574
Subtracting 0 from 640 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

The quotient of the division is 93044.3761574, and the remainder is 6.4e-07.
