We look at the division of 78164886 by 860 
Our goal is to divide 78164886 by 860.

Step 1:
When dividing 7 by 860, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 860

Going ahead to step 2:
If we divide 78 by 860, we get 0 and a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Append the next digit (1) from the dividend to 78 and continue with: 781 / 860

Step 3:
When dividing 781 by 860, we get 0 with a remainder of 781.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 781, we end up with 781.
Take the next digit (6) from the dividend and append it to 781, then repeat: 7816 / 860

Step 4:
The number 860 fits into 7816 9 times, leaving a remainder of 76.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 7740 from 7816 leaves us with 76.
Bring next digit (4) of the dividend behind the 76 and repeat the process: 764 / 860

Step 5:
860 can be fit into 764 0 times, resulting in a remainder of 764.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
The remainder is 764 after subtracting 0 from 764.
Append the next digit (8) from the dividend to 764 and continue with: 7648 / 860

Advancing to step 6:
7648 divided by 860 is 8 with a remainder of 768.
Record the quotient 8 as the next digit in the result. 
Result so far: 908.0
If we subtract 6880 from 7648, we get 768.
Fetch the next digit (8) from the dividend, attach it to 768 and continue: 7688 / 860

On to step 7:
If we divide 7688 by 860, we get 8 and a remainder of 808.
Write down 8 as next digit of the result. 
Result so far: 9088.0
The remainder is 808 after subtracting 6880 from 7688.
Grab the next digit (6) from the dividend, add it to 808, then carry on: 8086 / 860

On to step 8:
If we divide 8086 by 860, we get 9 and a remainder of 346.
Use 9 as the next digit of our solution. 
Result so far: 90889.0
Subtract 7740 from 8086 to get 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

On to step 9:
The number 860 fits into 3460 4 times, leaving a remainder of 20.
The next digit of our result is 4. 
Result so far: 90889.4
The remainder is 20 after subtracting 3440 from 3460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
When dividing 200 by 860, we get 0 with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 90889.4
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 11:
860 goes into 2000 2 times with a remainder of 280.
The number 2 becomes the next digit in our result. 
Result so far: 90889.402
Subtracting 1720 from 2000 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 12:
When dividing 2800 by 860, we get 3 with a remainder of 220.
Write down 3 as next digit of the result. 
Result so far: 90889.4023
Deduct 2580 from 2800 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 13:
860 can be fit into 2200 2 times, resulting in a remainder of 480.
Use 2 as the next digit of our solution. 
Result so far: 90889.40232
Subtracting 1720 from 2200 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 14:
If we divide 4800 by 860, we get 5 and a remainder of 500.
Record the quotient 5 as the next digit in the result. 
Result so far: 90889.402325
Subtract 4300 from 4800 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 15:
The number 860 fits into 5000 5 times, leaving a remainder of 700.
The number 5 becomes the next digit in our result. 
Result so far: 90889.4023255
If we subtract 4300 from 5000, we get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

In conclusion, the division gives 90889.4023255 with a balance of 7e-06.
