We look at the division of 86456478 by 845 
Our goal is to divide 86456478 by 845.

Moving on to step 1:
When dividing 8 by 845, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 845

Going ahead to step 2:
When dividing 86 by 845, we get 0 with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Include the next digit (4) from the dividend after 86, then repeat: 864 / 845

Moving on to step 3:
845 goes into 864 1 times with a remainder of 19.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 845 from 864 to get 19.
Grab the next digit (5) from the dividend, add it to 19, then carry on: 195 / 845

Step 4:
If we divide 195 by 845, we get 0 and a remainder of 195.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 195, we get 195.
Fetch the next digit (6) from the dividend, attach it to 195 and continue: 1956 / 845

On to step 5:
1956 divided by 845 is 2 with a remainder of 266.
Record the quotient 2 as the next digit in the result. 
Result so far: 102.0
Subtract 1690 from 1956 to get 266.
Append the next digit (4) from the dividend to 266 and continue with: 2664 / 845

Step 6:
845 can be fit into 2664 3 times, resulting in a remainder of 129.
Use 3 as the next digit of our solution. 
Result so far: 1023.0
If we subtract 2535 from 2664, we get 129.
Grab the next digit (7) from the dividend, add it to 129, then carry on: 1297 / 845

Let's proceed to step 7:
The number 845 fits into 1297 1 times, leaving a remainder of 452.
The next digit of our result is 1. 
Result so far: 10231.0
The remainder is 452 after subtracting 845 from 1297.
Bring next digit (8) of the dividend behind the 452 and repeat the process: 4528 / 845

On to step 8:
When dividing 4528 by 845, we get 5 with a remainder of 303.
Record the quotient 5 as the next digit in the result. 
Result so far: 102315.0
If we take 4225 away from 4528, we end up with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Moving on to step 9:
845 can be fit into 3030 3 times, resulting in a remainder of 495.
The number 3 becomes the next digit in our result. 
Result so far: 102315.3
Subtracting 2535 from 3030 leaves us with 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Let's proceed to step 10:
The number 845 fits into 4950 5 times, leaving a remainder of 725.
The next digit of our result is 5. 
Result so far: 102315.35
The remainder is 725 after subtracting 4225 from 4950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

Moving on to step 11:
The number 845 fits into 7250 8 times, leaving a remainder of 490.
Write down 8 as next digit of the result. 
Result so far: 102315.358
Subtract 6760 from 7250 to get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Advancing to step 12:
If we divide 4900 by 845, we get 5 and a remainder of 675.
Use 5 as the next digit of our solution. 
Result so far: 102315.3585
Subtracting 4225 from 4900 leaves us with 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

Moving on to step 13:
If we divide 6750 by 845, we get 7 and a remainder of 835.
The next digit of our result is 7. 
Result so far: 102315.35857
Subtracting 5915 from 6750 leaves us with 835.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8350, and continue the process.

Going ahead to step 14:
When dividing 8350 by 845, we get 9 with a remainder of 745.
The number 9 becomes the next digit in our result. 
Result so far: 102315.358579
If we subtract 7605 from 8350, we get 745.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7450, and continue the process.

Going ahead to step 15:
When dividing 7450 by 845, we get 8 with a remainder of 690.
The number 8 becomes the next digit in our result. 
Result so far: 102315.3585798
The remainder is 690 after subtracting 6760 from 7450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Moving on to step 16:
The number 845 fits into 6900 8 times, leaving a remainder of 140.
The number 8 becomes the next digit in our result. 
Result so far: 102315.35857988
If we take 6760 away from 6900, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The quotient of the division is 102315.35857988, and the remainder is 1.4e-07.
