We look at the division of 34121397 by 405 
We want to figure out the number of times 34121397 can be divided by 405.

Moving on to step 1:
405 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 405

Let's proceed to step 2:
34 divided by 405 is 0 with a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 34 leaves us with 34.
Take the next digit (1) from the dividend and append it to 34, then repeat: 341 / 405

Moving on to step 3:
341 divided by 405 is 0 with a remainder of 341.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 341 to get 341.
Include the next digit (2) from the dividend after 341, then repeat: 3412 / 405

Advancing to step 4:
If we divide 3412 by 405, we get 8 and a remainder of 172.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 3240 from 3412, we get 172.
Append the next digit (1) from the dividend to 172 and continue with: 1721 / 405

Advancing to step 5:
405 can be fit into 1721 4 times, resulting in a remainder of 101.
Put 4 as the next digit of the answer. 
Result so far: 84.0
The remainder is 101 after subtracting 1620 from 1721.
Fetch the next digit (3) from the dividend, attach it to 101 and continue: 1013 / 405

On to step 6:
405 goes into 1013 2 times with a remainder of 203.
Put 2 as the next digit of the answer. 
Result so far: 842.0
Deduct 810 from 1013 and we're left with 203.
Grab the next digit (9) from the dividend, add it to 203, then carry on: 2039 / 405

Step 7:
405 goes into 2039 5 times with a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 8425.0
Deduct 2025 from 2039 and we're left with 14.
Bring next digit (7) of the dividend behind the 14 and repeat the process: 147 / 405

Step 8:
If we divide 147 by 405, we get 0 and a remainder of 147.
The number 0 becomes the next digit in our result. 
Result so far: 84250.0
If we take 0 away from 147, we end up with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Let's proceed to step 9:
If we divide 1470 by 405, we get 3 and a remainder of 255.
The next digit of our result is 3. 
Result so far: 84250.3
Deduct 1215 from 1470 and we're left with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Step 10:
2550 divided by 405 is 6 with a remainder of 120.
Record the quotient 6 as the next digit in the result. 
Result so far: 84250.36
If we subtract 2430 from 2550, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 11:
If we divide 1200 by 405, we get 2 and a remainder of 390.
Record the quotient 2 as the next digit in the result. 
Result so far: 84250.362
Subtract 810 from 1200 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Advancing to step 12:
405 goes into 3900 9 times with a remainder of 255.
Record the quotient 9 as the next digit in the result. 
Result so far: 84250.3629
If we take 3645 away from 3900, we end up with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Going ahead to step 13:
If we divide 2550 by 405, we get 6 and a remainder of 120.
The number 6 becomes the next digit in our result. 
Result so far: 84250.36296
Subtract 2430 from 2550 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 14:
405 can be fit into 1200 2 times, resulting in a remainder of 390.
Record the quotient 2 as the next digit in the result. 
Result so far: 84250.362962
If we subtract 810 from 1200, we get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Let's proceed to step 15:
If we divide 3900 by 405, we get 9 and a remainder of 255.
The next digit of our result is 9. 
Result so far: 84250.3629629
Subtract 3645 from 3900 to get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

On to step 16:
The number 405 fits into 2550 6 times, leaving a remainder of 120.
Put 6 as the next digit of the answer. 
Result so far: 84250.36296296
Deduct 2430 from 2550 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

After the division, we end up with 84250.36296296 and a remainder of 1.2e-07.
