84579012 divided by 123 
We want to figure out the number of times 84579012 can be divided by 123.

Moving on to step 1:
If we divide 8 by 123, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 123

Let's proceed to step 2:
84 divided by 123 is 0 with a remainder of 84.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Include the next digit (5) from the dividend after 84, then repeat: 845 / 123

Going ahead to step 3:
The number 123 fits into 845 6 times, leaving a remainder of 107.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 738 from 845 and we're left with 107.
Grab the next digit (7) from the dividend, add it to 107, then carry on: 1077 / 123

Let's proceed to step 4:
1077 divided by 123 is 8 with a remainder of 93.
Use 8 as the next digit of our solution. 
Result so far: 68.0
The remainder is 93 after subtracting 984 from 1077.
Include the next digit (9) from the dividend after 93, then repeat: 939 / 123

Going ahead to step 5:
123 can be fit into 939 7 times, resulting in a remainder of 78.
The number 7 becomes the next digit in our result. 
Result so far: 687.0
If we subtract 861 from 939, we get 78.
Grab the next digit (0) from the dividend, add it to 78, then carry on: 780 / 123

Advancing to step 6:
123 goes into 780 6 times with a remainder of 42.
Record the quotient 6 as the next digit in the result. 
Result so far: 6876.0
Deduct 738 from 780 and we're left with 42.
Fetch the next digit (1) from the dividend, attach it to 42 and continue: 421 / 123

Moving on to step 7:
123 can be fit into 421 3 times, resulting in a remainder of 52.
Use 3 as the next digit of our solution. 
Result so far: 68763.0
Subtract 369 from 421 to get 52.
Fetch the next digit (2) from the dividend, attach it to 52 and continue: 522 / 123

Advancing to step 8:
522 divided by 123 is 4 with a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 687634.0
If we take 492 away from 522, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
If we divide 300 by 123, we get 2 and a remainder of 54.
The number 2 becomes the next digit in our result. 
Result so far: 687634.2
Subtract 246 from 300 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 10:
If we divide 540 by 123, we get 4 and a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 687634.24
Subtracting 492 from 540 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 11:
123 can be fit into 480 3 times, resulting in a remainder of 111.
The number 3 becomes the next digit in our result. 
Result so far: 687634.243
Subtract 369 from 480 to get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Going ahead to step 12:
1110 divided by 123 is 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 687634.2439
If we subtract 1107 from 1110, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 13:
The number 123 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 687634.2439
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 14:
If we divide 300 by 123, we get 2 and a remainder of 54.
The next digit of our result is 2. 
Result so far: 687634.243902
If we subtract 246 from 300, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 15:
123 can be fit into 540 4 times, resulting in a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 687634.2439024
Deduct 492 from 540 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 16:
480 divided by 123 is 3 with a remainder of 111.
Record the quotient 3 as the next digit in the result. 
Result so far: 687634.24390243
The remainder is 111 after subtracting 369 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

The final outcome is 687634.24390243, with a leftover of 1.11e-07.
