We're dividing 80586454 by 120 
We're looking to find how many times 120 goes into 80586454.

On to step 1:
If we divide 8 by 120, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 120

Going ahead to step 2:
80 divided by 120 is 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Append the next digit (5) from the dividend to 80 and continue with: 805 / 120

Going ahead to step 3:
120 can be fit into 805 6 times, resulting in a remainder of 85.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 720 from 805 to get 85.
Grab the next digit (8) from the dividend, add it to 85, then carry on: 858 / 120

Let's proceed to step 4:
When dividing 858 by 120, we get 7 with a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 67.0
Deduct 840 from 858 and we're left with 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 120

On to step 5:
When dividing 186 by 120, we get 1 with a remainder of 66.
Record the quotient 1 as the next digit in the result. 
Result so far: 671.0
If we take 120 away from 186, we end up with 66.
Take the next digit (4) from the dividend and append it to 66, then repeat: 664 / 120

Step 6:
The number 120 fits into 664 5 times, leaving a remainder of 64.
The number 5 becomes the next digit in our result. 
Result so far: 6715.0
If we subtract 600 from 664, we get 64.
Include the next digit (5) from the dividend after 64, then repeat: 645 / 120

Let's proceed to step 7:
The number 120 fits into 645 5 times, leaving a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 67155.0
Subtracting 600 from 645 leaves us with 45.
Include the next digit (4) from the dividend after 45, then repeat: 454 / 120

Going ahead to step 8:
When dividing 454 by 120, we get 3 with a remainder of 94.
Use 3 as the next digit of our solution. 
Result so far: 671553.0
If we take 360 away from 454, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 9:
120 goes into 940 7 times with a remainder of 100.
Use 7 as the next digit of our solution. 
Result so far: 671553.7
If we take 840 away from 940, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 10:
120 goes into 1000 8 times with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 671553.78
If we subtract 960 from 1000, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
120 goes into 400 3 times with a remainder of 40.
Put 3 as the next digit of the answer. 
Result so far: 671553.783
Subtracting 360 from 400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 12:
400 divided by 120 is 3 with a remainder of 40.
Record the quotient 3 as the next digit in the result. 
Result so far: 671553.7833
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 671553.7833 with a balance of 0.0004.
