49147221 ÷ 123 
We're looking to find how many times 123 goes into 49147221.

Step 1:
When dividing 4 by 123, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 123

Let's proceed to step 2:
123 goes into 49 0 times with a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 49 leaves us with 49.
Take the next digit (1) from the dividend and append it to 49, then repeat: 491 / 123

Moving on to step 3:
If we divide 491 by 123, we get 3 and a remainder of 122.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 369 from 491 to get 122.
Include the next digit (4) from the dividend after 122, then repeat: 1224 / 123

Advancing to step 4:
The number 123 fits into 1224 9 times, leaving a remainder of 117.
The next digit of our result is 9. 
Result so far: 39.0
If we subtract 1107 from 1224, we get 117.
Include the next digit (7) from the dividend after 117, then repeat: 1177 / 123

Advancing to step 5:
1177 divided by 123 is 9 with a remainder of 70.
Write down 9 as next digit of the result. 
Result so far: 399.0
Subtract 1107 from 1177 to get 70.
Bring next digit (2) of the dividend behind the 70 and repeat the process: 702 / 123

Let's proceed to step 6:
702 divided by 123 is 5 with a remainder of 87.
Use 5 as the next digit of our solution. 
Result so far: 3995.0
Subtracting 615 from 702 leaves us with 87.
Take the next digit (2) from the dividend and append it to 87, then repeat: 872 / 123

Advancing to step 7:
872 divided by 123 is 7 with a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 39957.0
Deduct 861 from 872 and we're left with 11.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 123

Let's proceed to step 8:
The number 123 fits into 111 0 times, leaving a remainder of 111.
Record the quotient 0 as the next digit in the result. 
Result so far: 399570.0
If we subtract 0 from 111, we 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.

Advancing to step 9:
123 can be fit into 1110 9 times, resulting in a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 399570.9
The remainder is 3 after subtracting 1107 from 1110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 10:
If we divide 30 by 123, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 399570.9
Deduct 0 from 30 and we're left 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.

Going ahead to step 11:
300 divided by 123 is 2 with a remainder of 54.
Record the quotient 2 as the next digit in the result. 
Result so far: 399570.902
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.

On to step 12:
The number 123 fits into 540 4 times, leaving a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 399570.9024
If we subtract 492 from 540, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 13:
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: 399570.90243
If we subtract 369 from 480, we 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.

Let's proceed to step 14:
123 can be fit into 1110 9 times, resulting in a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 399570.902439
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.

Moving on to step 15:
When dividing 30 by 123, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 399570.902439
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 16:
When dividing 300 by 123, we get 2 with a remainder of 54.
Put 2 as the next digit of the answer. 
Result so far: 399570.90243902
Subtracting 246 from 300 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

After the division, we end up with 399570.90243902 and a remainder of 5.4e-08.
