3123207 divided by 123 
Let's see how many times 123 fits into 3123207.

Advancing to step 1:
The number 123 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 123

Going ahead to step 2:
123 can be fit into 31 0 times, resulting in a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Include the next digit (2) from the dividend after 31, then repeat: 312 / 123

Let's proceed to step 3:
312 divided by 123 is 2 with a remainder of 66.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 246 from 312 and we're left with 66.
Take the next digit (3) from the dividend and append it to 66, then repeat: 663 / 123

Advancing to step 4:
If we divide 663 by 123, we get 5 and a remainder of 48.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
If we take 615 away from 663, we end up with 48.
Include the next digit (2) from the dividend after 48, then repeat: 482 / 123

Going ahead to step 5:
When dividing 482 by 123, we get 3 with a remainder of 113.
Record the quotient 3 as the next digit in the result. 
Result so far: 253.0
Subtract 369 from 482 to get 113.
Fetch the next digit (0) from the dividend, attach it to 113 and continue: 1130 / 123

Step 6:
123 goes into 1130 9 times with a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 2539.0
Subtract 1107 from 1130 to get 23.
Grab the next digit (7) from the dividend, add it to 23, then carry on: 237 / 123

Moving on to step 7:
The number 123 fits into 237 1 times, leaving a remainder of 114.
Use 1 as the next digit of our solution. 
Result so far: 25391.0
Deduct 123 from 237 and we're left with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Going ahead to step 8:
The number 123 fits into 1140 9 times, leaving a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 25391.9
Deduct 1107 from 1140 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 9:
When dividing 330 by 123, we get 2 with a remainder of 84.
The number 2 becomes the next digit in our result. 
Result so far: 25391.92
If we take 246 away from 330, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 10:
If we divide 840 by 123, we get 6 and a remainder of 102.
Put 6 as the next digit of the answer. 
Result so far: 25391.926
Subtracting 738 from 840 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Step 11:
123 goes into 1020 8 times with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 25391.9268
Subtracting 984 from 1020 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 12:
360 divided by 123 is 2 with a remainder of 114.
The number 2 becomes the next digit in our result. 
Result so far: 25391.92682
Subtract 246 from 360 to get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Let's proceed to step 13:
123 can be fit into 1140 9 times, resulting in a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 25391.926829
The remainder is 33 after subtracting 1107 from 1140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 14:
If we divide 330 by 123, we get 2 and a remainder of 84.
Use 2 as the next digit of our solution. 
Result so far: 25391.9268292
If we subtract 246 from 330, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 15:
123 goes into 840 6 times with a remainder of 102.
Write down 6 as next digit of the result. 
Result so far: 25391.92682926
If we take 738 away from 840, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

The quotient of the division is 25391.92682926, and the remainder is 1.02e-07.
