78589054 ÷ 171 
We want to figure out the number of times 78589054 can be divided by 171.

Moving on to step 1:
If we divide 7 by 171, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 171

On to step 2:
78 divided by 171 is 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Bring next digit (5) of the dividend behind the 78 and repeat the process: 785 / 171

On to step 3:
The number 171 fits into 785 4 times, leaving a remainder of 101.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 684 from 785 to get 101.
Grab the next digit (8) from the dividend, add it to 101, then carry on: 1018 / 171

Moving on to step 4:
The number 171 fits into 1018 5 times, leaving a remainder of 163.
Use 5 as the next digit of our solution. 
Result so far: 45.0
The remainder is 163 after subtracting 855 from 1018.
Grab the next digit (9) from the dividend, add it to 163, then carry on: 1639 / 171

Let's proceed to step 5:
When dividing 1639 by 171, we get 9 with a remainder of 100.
The number 9 becomes the next digit in our result. 
Result so far: 459.0
Deduct 1539 from 1639 and we're left with 100.
Append the next digit (0) from the dividend to 100 and continue with: 1000 / 171

Moving on to step 6:
If we divide 1000 by 171, we get 5 and a remainder of 145.
Write down 5 as next digit of the result. 
Result so far: 4595.0
Subtract 855 from 1000 to get 145.
Fetch the next digit (5) from the dividend, attach it to 145 and continue: 1455 / 171

Step 7:
171 goes into 1455 8 times with a remainder of 87.
Record the quotient 8 as the next digit in the result. 
Result so far: 45958.0
If we subtract 1368 from 1455, we get 87.
Include the next digit (4) from the dividend after 87, then repeat: 874 / 171

On to step 8:
If we divide 874 by 171, we get 5 and a remainder of 19.
Put 5 as the next digit of the answer. 
Result so far: 459585.0
The remainder is 19 after subtracting 855 from 874.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 9:
171 can be fit into 190 1 times, resulting in a remainder of 19.
The next digit of our result is 1. 
Result so far: 459585.1
If we take 171 away from 190, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 10:
When dividing 190 by 171, we get 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 459585.11
If we take 171 away from 190, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

In conclusion, the division gives 459585.11 with a balance of 0.019.
