35518339 ÷ 408 
Our goal is to divide 35518339 by 408.

Moving on to step 1:
408 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 408

Step 2:
If we divide 35 by 408, we get 0 and a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Grab the next digit (5) from the dividend, add it to 35, then carry on: 355 / 408

Step 3:
408 goes into 355 0 times with a remainder of 355.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 355 leaves us with 355.
Grab the next digit (1) from the dividend, add it to 355, then carry on: 3551 / 408

Moving on to step 4:
408 goes into 3551 8 times with a remainder of 287.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 3264 from 3551 leaves us with 287.
Bring next digit (8) of the dividend behind the 287 and repeat the process: 2878 / 408

Advancing to step 5:
2878 divided by 408 is 7 with a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 87.0
If we subtract 2856 from 2878, we get 22.
Grab the next digit (3) from the dividend, add it to 22, then carry on: 223 / 408

Moving on to step 6:
The number 408 fits into 223 0 times, leaving a remainder of 223.
The number 0 becomes the next digit in our result. 
Result so far: 870.0
Subtract 0 from 223 to get 223.
Include the next digit (3) from the dividend after 223, then repeat: 2233 / 408

On to step 7:
408 goes into 2233 5 times with a remainder of 193.
Use 5 as the next digit of our solution. 
Result so far: 8705.0
Subtract 2040 from 2233 to get 193.
Include the next digit (9) from the dividend after 193, then repeat: 1939 / 408

Let's proceed to step 8:
1939 divided by 408 is 4 with a remainder of 307.
The number 4 becomes the next digit in our result. 
Result so far: 87054.0
If we subtract 1632 from 1939, we get 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

On to step 9:
408 can be fit into 3070 7 times, resulting in a remainder of 214.
Use 7 as the next digit of our solution. 
Result so far: 87054.7
If we subtract 2856 from 3070, we get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

On to step 10:
408 goes into 2140 5 times with a remainder of 100.
The next digit of our result is 5. 
Result so far: 87054.75
Subtract 2040 from 2140 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 11:
408 goes into 1000 2 times with a remainder of 184.
Use 2 as the next digit of our solution. 
Result so far: 87054.752
The remainder is 184 after subtracting 816 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 12:
When dividing 1840 by 408, we get 4 with a remainder of 208.
The number 4 becomes the next digit in our result. 
Result so far: 87054.7524
Subtract 1632 from 1840 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 13:
2080 divided by 408 is 5 with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 87054.75245
Subtracting 2040 from 2080 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 14:
400 divided by 408 is 0 with a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 87054.75245
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 15:
408 can be fit into 4000 9 times, resulting in a remainder of 328.
Record the quotient 9 as the next digit in the result. 
Result so far: 87054.7524509
The remainder is 328 after subtracting 3672 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Advancing to step 16:
3280 divided by 408 is 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 87054.75245098
Subtract 3264 from 3280 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 87054.75245098 with a remainder of 1.6e-08.
