We divide 84258961 by 123
We want to divide 84258961 by 123.

Advancing to step 1:
The number 123 fits into 8 0 times, leaving 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.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 123

Advancing to step 2:
If we divide 84 by 123, we get 0 and a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 84, we end up with 84.
Bring next digit (2) of the dividend behind the 84 and repeat the process: 842 / 123

Moving on to step 3:
The number 123 fits into 842 6 times, leaving a remainder of 104.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 738 from 842 leaves us with 104.
Bring next digit (5) of the dividend behind the 104 and repeat the process: 1045 / 123

Let's proceed to step 4:
When dividing 1045 by 123, we get 8 with a remainder of 61.
The next digit of our result is 8. 
Result so far: 68.0
The remainder is 61 after subtracting 984 from 1045.
Bring next digit (8) of the dividend behind the 61 and repeat the process: 618 / 123

Let's proceed to step 5:
If we divide 618 by 123, we get 5 and a remainder of 3.
The next digit of our result is 5. 
Result so far: 685.0
Subtracting 615 from 618 leaves us with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 123

Moving on to step 6:
123 goes into 39 0 times with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 6850.0
Deduct 0 from 39 and we're left with 39.
Include the next digit (6) from the dividend after 39, then repeat: 396 / 123

On to step 7:
396 divided by 123 is 3 with a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 68503.0
Subtracting 369 from 396 leaves us with 27.
Bring next digit (1) of the dividend behind the 27 and repeat the process: 271 / 123

Advancing to step 8:
123 goes into 271 2 times with a remainder of 25.
Put 2 as the next digit of the answer. 
Result so far: 685032.0
If we take 246 away from 271, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 9:
250 divided by 123 is 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 685032.2
Subtracting 246 from 250 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
The number 123 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 685032.2
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
If we divide 400 by 123, we get 3 and a remainder of 31.
The next digit of our result is 3. 
Result so far: 685032.203
Deduct 369 from 400 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 12:
123 can be fit into 310 2 times, resulting in a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 685032.2032
If we take 246 away from 310, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 13:
123 goes into 640 5 times with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 685032.20325
If we subtract 615 from 640, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 14:
250 divided by 123 is 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 685032.203252
Deduct 246 from 250 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 15:
When dividing 40 by 123, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 685032.203252
Subtract 0 from 40 to 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 16:
123 can be fit into 400 3 times, resulting in a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 685032.20325203
If we take 369 away from 400, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The final result is 685032.20325203 with a remainder of 3.1e-08.
