58123739 ÷ 13 
We want to divide 58123739 by 13.

On to step 1:
When dividing 5 by 13, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 13

Moving on to step 2:
The number 13 fits into 58 4 times, leaving a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 52 from 58, we get 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 13

Step 3:
61 divided by 13 is 4 with a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 44.0
If we subtract 52 from 61, we get 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 13

Advancing to step 4:
The number 13 fits into 92 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 447.0
If we take 91 away from 92, we end up with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 13

Advancing to step 5:
The number 13 fits into 13 1 times, leaving a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 4471.0
If we take 13 away from 13, we end up with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 13

Moving on to step 6:
When dividing 7 by 13, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 44710.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 13

Step 7:
When dividing 73 by 13, we get 5 with a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 447105.0
The remainder is 8 after subtracting 65 from 73.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 13

On to step 8:
If we divide 89 by 13, we get 6 and a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 4471056.0
Subtracting 78 from 89 leaves us 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.

Step 9:
When dividing 110 by 13, we get 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 4471056.8
Subtracting 104 from 110 leaves us 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.

On to step 10:
13 can be fit into 60 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 4471056.84
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.

Step 11:
80 divided by 13 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 4471056.846
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.

Going ahead to step 12:
The number 13 fits into 20 1 times, leaving a remainder of 7.
The next digit of our result is 1. 
Result so far: 4471056.8461
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.

On to step 13:
70 divided by 13 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 4471056.84615
If we subtract 65 from 70, we get 5.
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 14:
The number 13 fits into 50 3 times, leaving a remainder of 11.
The next digit of our result is 3. 
Result so far: 4471056.846153
Subtracting 39 from 50 leaves us 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 15:
If we divide 110 by 13, we get 8 and a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 4471056.8461538
Subtract 104 from 110 to 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.

Advancing to step 16:
If we divide 60 by 13, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 4471056.84615384
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.

After the division, we end up with 4471056.84615384 and a remainder of 8e-09.
