58321491 ÷ 405 
Our goal is to divide 58321491 by 405.

On to step 1:
The number 405 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 405

On to step 2:
405 goes into 58 0 times with a remainder of 58.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 58 after subtracting 0 from 58.
Fetch the next digit (3) from the dividend, attach it to 58 and continue: 583 / 405

Step 3:
When dividing 583 by 405, we get 1 with a remainder of 178.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 405 away from 583, we end up with 178.
Append the next digit (2) from the dividend to 178 and continue with: 1782 / 405

Let's proceed to step 4:
1782 divided by 405 is 4 with a remainder of 162.
The next digit of our result is 4. 
Result so far: 14.0
Deduct 1620 from 1782 and we're left with 162.
Include the next digit (1) from the dividend after 162, then repeat: 1621 / 405

Advancing to step 5:
1621 divided by 405 is 4 with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 144.0
Deduct 1620 from 1621 and we're left with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 405

Moving on to step 6:
14 divided by 405 is 0 with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 1440.0
Deduct 0 from 14 and we're left with 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 405

Moving on to step 7:
149 divided by 405 is 0 with a remainder of 149.
The number 0 becomes the next digit in our result. 
Result so far: 14400.0
The remainder is 149 after subtracting 0 from 149.
Fetch the next digit (1) from the dividend, attach it to 149 and continue: 1491 / 405

Moving on to step 8:
1491 divided by 405 is 3 with a remainder of 276.
Put 3 as the next digit of the answer. 
Result so far: 144003.0
The remainder is 276 after subtracting 1215 from 1491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

On to step 9:
405 can be fit into 2760 6 times, resulting in a remainder of 330.
Record the quotient 6 as the next digit in the result. 
Result so far: 144003.6
Deduct 2430 from 2760 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Step 10:
If we divide 3300 by 405, we get 8 and a remainder of 60.
Record the quotient 8 as the next digit in the result. 
Result so far: 144003.68
If we subtract 3240 from 3300, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 11:
When dividing 600 by 405, we get 1 with a remainder of 195.
The next digit of our result is 1. 
Result so far: 144003.681
If we take 405 away from 600, we end up with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

On to step 12:
405 can be fit into 1950 4 times, resulting in a remainder of 330.
Put 4 as the next digit of the answer. 
Result so far: 144003.6814
Subtract 1620 from 1950 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Let's proceed to step 13:
The number 405 fits into 3300 8 times, leaving a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 144003.68148
Subtract 3240 from 3300 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 14:
600 divided by 405 is 1 with a remainder of 195.
The next digit of our result is 1. 
Result so far: 144003.681481
If we take 405 away from 600, we end up with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Moving on to step 15:
405 can be fit into 1950 4 times, resulting in a remainder of 330.
Record the quotient 4 as the next digit in the result. 
Result so far: 144003.6814814
Deduct 1620 from 1950 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Step 16:
When dividing 3300 by 405, we get 8 with a remainder of 60.
Use 8 as the next digit of our solution. 
Result so far: 144003.68148148
If we subtract 3240 from 3300, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 144003.68148148 with a remainder of 6e-08.
