23552103 ÷ 405 
We want to figure out the number of times 23552103 can be divided by 405.

Moving on to step 1:
405 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 405

On to step 2:
405 goes into 23 0 times with a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Grab the next digit (5) from the dividend, add it to 23, then carry on: 235 / 405

Step 3:
405 goes into 235 0 times with a remainder of 235.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 235, we end up with 235.
Bring next digit (5) of the dividend behind the 235 and repeat the process: 2355 / 405

On to step 4:
2355 divided by 405 is 5 with a remainder of 330.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 2025 away from 2355, we end up with 330.
Append the next digit (2) from the dividend to 330 and continue with: 3302 / 405

Step 5:
405 can be fit into 3302 8 times, resulting in a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 58.0
Subtracting 3240 from 3302 leaves us with 62.
Append the next digit (1) from the dividend to 62 and continue with: 621 / 405

Moving on to step 6:
When dividing 621 by 405, we get 1 with a remainder of 216.
Use 1 as the next digit of our solution. 
Result so far: 581.0
Deduct 405 from 621 and we're left with 216.
Bring next digit (0) of the dividend behind the 216 and repeat the process: 2160 / 405

Let's proceed to step 7:
When dividing 2160 by 405, we get 5 with a remainder of 135.
The next digit of our result is 5. 
Result so far: 5815.0
If we subtract 2025 from 2160, we get 135.
Bring next digit (3) of the dividend behind the 135 and repeat the process: 1353 / 405

Step 8:
405 can be fit into 1353 3 times, resulting in a remainder of 138.
Record the quotient 3 as the next digit in the result. 
Result so far: 58153.0
Subtracting 1215 from 1353 leaves us with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

On to step 9:
The number 405 fits into 1380 3 times, leaving a remainder of 165.
Write down 3 as next digit of the result. 
Result so far: 58153.3
Subtracting 1215 from 1380 leaves us with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

On to step 10:
405 goes into 1650 4 times with a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 58153.34
The remainder is 30 after subtracting 1620 from 1650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
When dividing 300 by 405, we get 0 with a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 58153.34
If we take 0 away from 300, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 12:
3000 divided by 405 is 7 with a remainder of 165.
The next digit of our result is 7. 
Result so far: 58153.3407
Subtracting 2835 from 3000 leaves us with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Moving on to step 13:
If we divide 1650 by 405, we get 4 and a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 58153.34074
Subtract 1620 from 1650 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 14:
300 divided by 405 is 0 with a remainder of 300.
The next digit of our result is 0. 
Result so far: 58153.34074
Deduct 0 from 300 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 15:
The number 405 fits into 3000 7 times, leaving a remainder of 165.
The next digit of our result is 7. 
Result so far: 58153.3407407
Deduct 2835 from 3000 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Going ahead to step 16:
The number 405 fits into 1650 4 times, leaving a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 58153.34074074
Subtract 1620 from 1650 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 58153.34074074 and a remainder of 3e-08.
