43157090 ÷ 13 
Our goal is to divide 43157090 by 13.

Advancing to step 1:
4 divided by 13 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 13

Going ahead to step 2:
13 can be fit into 43 3 times, resulting in a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 4 after subtracting 39 from 43.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 13

Advancing to step 3:
41 divided by 13 is 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Subtract 39 from 41 to get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 13

Step 4:
13 can be fit into 25 1 times, resulting in a remainder of 12.
The next digit of our result is 1. 
Result so far: 331.0
If we subtract 13 from 25, we get 12.
Bring next digit (7) of the dividend behind the 12 and repeat the process: 127 / 13

Advancing to step 5:
127 divided by 13 is 9 with a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 3319.0
If we subtract 117 from 127, we get 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 13

Going ahead to step 6:
13 goes into 100 7 times with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 33197.0
If we take 91 away from 100, we end up with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 13

Advancing to step 7:
13 goes into 99 7 times with a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 331977.0
Subtracting 91 from 99 leaves us with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 13

Step 8:
The number 13 fits into 80 6 times, leaving a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 3319776.0
If we subtract 78 from 80, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
The number 13 fits into 20 1 times, leaving a remainder of 7.
The next digit of our result is 1. 
Result so far: 3319776.1
Subtracting 13 from 20 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 10:
If we divide 70 by 13, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 3319776.15
If we take 65 away from 70, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 11:
If we divide 50 by 13, we get 3 and a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 3319776.153
If we take 39 away from 50, we end up with 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 12:
If we divide 110 by 13, we get 8 and a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 3319776.1538
Deduct 104 from 110 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 13:
When dividing 60 by 13, we get 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 3319776.15384
If we take 52 away from 60, we end up 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.

Moving on to step 14:
When dividing 80 by 13, we get 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 3319776.153846
If we take 78 away from 80, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 15:
13 goes into 20 1 times with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 3319776.1538461
Subtracting 13 from 20 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 16:
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: 3319776.15384615
Deduct 65 from 70 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

In conclusion, the division gives 3319776.15384615 with a balance of 5e-09.
