We divide 48657391 by 13
Let's see how many times 13 fits into 48657391.

On to step 1:
The number 13 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 13

Let's proceed to step 2:
48 divided by 13 is 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 39 from 48 and we're left with 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 13

Going ahead to step 3:
The number 13 fits into 96 7 times, leaving a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
Deduct 91 from 96 and we're left with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 13

Let's proceed to step 4:
13 can be fit into 55 4 times, resulting in a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 374.0
Deduct 52 from 55 and we're left with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 13

Advancing to step 5:
13 goes into 37 2 times with a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 3742.0
Subtracting 26 from 37 leaves us with 11.
Fetch the next digit (3) from the dividend, attach it to 11 and continue: 113 / 13

Advancing to step 6:
The number 13 fits into 113 8 times, leaving a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 37428.0
Subtracting 104 from 113 leaves us with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 13

Let's proceed to step 7:
When dividing 99 by 13, we get 7 with a remainder of 8.
The next digit of our result is 7. 
Result so far: 374287.0
Deduct 91 from 99 and we're left with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 13

Advancing to step 8:
13 goes into 81 6 times with a remainder of 3.
The next digit of our result is 6. 
Result so far: 3742876.0
Subtract 78 from 81 to 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 9:
13 can be fit into 30 2 times, resulting in a remainder of 4.
The next digit of our result is 2. 
Result so far: 3742876.2
If we take 26 away from 30, we end up 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.

Moving on to step 10:
The number 13 fits into 40 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 3742876.23
Deduct 39 from 40 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 11:
When dividing 10 by 13, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 3742876.23
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
If we divide 100 by 13, we get 7 and a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 3742876.2307
Deduct 91 from 100 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 13:
When dividing 90 by 13, we get 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 3742876.23076
If we subtract 78 from 90, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 14:
The number 13 fits into 120 9 times, leaving a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 3742876.230769
The remainder is 3 after subtracting 117 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 15:
13 goes into 30 2 times with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 3742876.2307692
If we take 26 away from 30, we end up 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 16:
40 divided by 13 is 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 3742876.23076923
Subtract 39 from 40 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Our division results in 3742876.23076923 with a remaining 1e-09.
