We divide 12157852 by 123
We're looking to find how many times 123 goes into 12157852.

On to step 1:
The number 123 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 123

Let's proceed to step 2:
12 divided by 123 is 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 123

Let's proceed to step 3:
If we divide 121 by 123, we get 0 and a remainder of 121.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 121 after subtracting 0 from 121.
Bring next digit (5) of the dividend behind the 121 and repeat the process: 1215 / 123

On to step 4:
123 can be fit into 1215 9 times, resulting in a remainder of 108.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 1107 from 1215 leaves us with 108.
Fetch the next digit (7) from the dividend, attach it to 108 and continue: 1087 / 123

On to step 5:
The number 123 fits into 1087 8 times, leaving a remainder of 103.
Write down 8 as next digit of the result. 
Result so far: 98.0
Deduct 984 from 1087 and we're left with 103.
Grab the next digit (8) from the dividend, add it to 103, then carry on: 1038 / 123

Step 6:
1038 divided by 123 is 8 with a remainder of 54.
The next digit of our result is 8. 
Result so far: 988.0
If we subtract 984 from 1038, we get 54.
Fetch the next digit (5) from the dividend, attach it to 54 and continue: 545 / 123

Advancing to step 7:
If we divide 545 by 123, we get 4 and a remainder of 53.
The next digit of our result is 4. 
Result so far: 9884.0
If we subtract 492 from 545, we get 53.
Append the next digit (2) from the dividend to 53 and continue with: 532 / 123

Going ahead to step 8:
123 goes into 532 4 times with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 98844.0
If we subtract 492 from 532, 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 9:
400 divided by 123 is 3 with a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 98844.3
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.

Going ahead to step 10:
310 divided by 123 is 2 with a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 98844.32
Deduct 246 from 310 and we're left 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 11:
When dividing 640 by 123, we get 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 98844.325
Subtracting 615 from 640 leaves us 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.

On to step 12:
123 can be fit into 250 2 times, resulting in a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 98844.3252
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.

Let's proceed to step 13:
If we divide 40 by 123, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 98844.3252
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.

Going ahead to step 14:
123 can be fit into 400 3 times, resulting in a remainder of 31.
The next digit of our result is 3. 
Result so far: 98844.325203
The remainder is 31 after subtracting 369 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 15:
123 can be fit into 310 2 times, resulting in a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 98844.3252032
Deduct 246 from 310 and we're left 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.

Advancing to step 16:
If we divide 640 by 123, we get 5 and a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 98844.32520325
Subtracting 615 from 640 leaves us 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.

The final result is 98844.32520325 with a remainder of 2.5e-08.
