49972139 divided by 488 
We want to figure out the number of times 49972139 can be divided by 488.

Step 1:
The number 488 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 488

Advancing to step 2:
If we divide 49 by 488, we get 0 and a remainder of 49.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 49 after subtracting 0 from 49.
Grab the next digit (9) from the dividend, add it to 49, then carry on: 499 / 488

On to step 3:
The number 488 fits into 499 1 times, leaving a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 488 away from 499, we end up with 11.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 488

Advancing to step 4:
If we divide 117 by 488, we get 0 and a remainder of 117.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 117 leaves us with 117.
Bring next digit (2) of the dividend behind the 117 and repeat the process: 1172 / 488

Let's proceed to step 5:
The number 488 fits into 1172 2 times, leaving a remainder of 196.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
Subtracting 976 from 1172 leaves us with 196.
Fetch the next digit (1) from the dividend, attach it to 196 and continue: 1961 / 488

Step 6:
1961 divided by 488 is 4 with a remainder of 9.
The next digit of our result is 4. 
Result so far: 1024.0
If we take 1952 away from 1961, we end up with 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 488

Step 7:
The number 488 fits into 93 0 times, leaving a remainder of 93.
The next digit of our result is 0. 
Result so far: 10240.0
Subtracting 0 from 93 leaves us with 93.
Fetch the next digit (9) from the dividend, attach it to 93 and continue: 939 / 488

Going ahead to step 8:
488 can be fit into 939 1 times, resulting in a remainder of 451.
Put 1 as the next digit of the answer. 
Result so far: 102401.0
Subtracting 488 from 939 leaves us with 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Step 9:
The number 488 fits into 4510 9 times, leaving a remainder of 118.
Use 9 as the next digit of our solution. 
Result so far: 102401.9
Deduct 4392 from 4510 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Step 10:
488 goes into 1180 2 times with a remainder of 204.
Put 2 as the next digit of the answer. 
Result so far: 102401.92
The remainder is 204 after subtracting 976 from 1180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Moving on to step 11:
When dividing 2040 by 488, we get 4 with a remainder of 88.
Use 4 as the next digit of our solution. 
Result so far: 102401.924
If we take 1952 away from 2040, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 12:
488 can be fit into 880 1 times, resulting in a remainder of 392.
Record the quotient 1 as the next digit in the result. 
Result so far: 102401.9241
Deduct 488 from 880 and we're left with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

On to step 13:
The number 488 fits into 3920 8 times, leaving a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 102401.92418
Subtract 3904 from 3920 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 14:
488 can be fit into 160 0 times, resulting in a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 102401.92418
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 15:
1600 divided by 488 is 3 with a remainder of 136.
The number 3 becomes the next digit in our result. 
Result so far: 102401.9241803
Deduct 1464 from 1600 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

On to step 16:
If we divide 1360 by 488, we get 2 and a remainder of 384.
Record the quotient 2 as the next digit in the result. 
Result so far: 102401.92418032
The remainder is 384 after subtracting 976 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Our division results in 102401.92418032 with a remaining 3.84e-07.
