56436971 ÷ 13 
Our goal is to divide 56436971 by 13.

On to step 1:
13 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 13

Advancing to step 2:
If we divide 56 by 13, we get 4 and a remainder of 4.
The next digit of our result is 4. 
Result so far: 4.0
If we take 52 away from 56, we end up with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 13

Advancing to step 3:
The number 13 fits into 44 3 times, leaving a remainder of 5.
The next digit of our result is 3. 
Result so far: 43.0
Subtract 39 from 44 to get 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 13

On to step 4:
13 can be fit into 53 4 times, resulting in a remainder of 1.
The next digit of our result is 4. 
Result so far: 434.0
Subtracting 52 from 53 leaves us with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 13

Let's proceed to step 5:
When dividing 16 by 13, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 4341.0
Subtract 13 from 16 to get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 13

Advancing to step 6:
13 goes into 39 3 times with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 43413.0
If we take 39 away from 39, we end up with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 13

Going ahead to step 7:
13 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 434130.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 13

On to step 8:
13 goes into 71 5 times with a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 4341305.0
If we subtract 65 from 71, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
13 goes into 60 4 times with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 4341305.4
Subtracting 52 from 60 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
80 divided by 13 is 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 4341305.46
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 11:
When dividing 20 by 13, we get 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 4341305.461
Subtract 13 from 20 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 12:
13 can be fit into 70 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 4341305.4615
The remainder is 5 after subtracting 65 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 13:
If we divide 50 by 13, we get 3 and a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 4341305.46153
If we subtract 39 from 50, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 14:
The number 13 fits into 110 8 times, leaving a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 4341305.461538
If we subtract 104 from 110, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 15:
13 can be fit into 60 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 4341305.4615384
Deduct 52 from 60 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 16:
When dividing 80 by 13, we get 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 4341305.46153846
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 4341305.46153846 and a remainder of 2e-09.
