We look at the division of 42916511 by 408 
We want to figure out the number of times 42916511 can be divided by 408.

Advancing to step 1:
The number 408 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 408

Step 2:
408 can be fit into 42 0 times, resulting in a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Bring next digit (9) of the dividend behind the 42 and repeat the process: 429 / 408

Moving on to step 3:
When dividing 429 by 408, we get 1 with a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 408 from 429 to get 21.
Take the next digit (1) from the dividend and append it to 21, then repeat: 211 / 408

On to step 4:
If we divide 211 by 408, we get 0 and a remainder of 211.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 211 to get 211.
Bring next digit (6) of the dividend behind the 211 and repeat the process: 2116 / 408

Going ahead to step 5:
408 goes into 2116 5 times with a remainder of 76.
Put 5 as the next digit of the answer. 
Result so far: 105.0
Subtracting 2040 from 2116 leaves us with 76.
Include the next digit (5) from the dividend after 76, then repeat: 765 / 408

Step 6:
408 can be fit into 765 1 times, resulting in a remainder of 357.
The next digit of our result is 1. 
Result so far: 1051.0
The remainder is 357 after subtracting 408 from 765.
Bring next digit (1) of the dividend behind the 357 and repeat the process: 3571 / 408

Moving on to step 7:
The number 408 fits into 3571 8 times, leaving a remainder of 307.
Record the quotient 8 as the next digit in the result. 
Result so far: 10518.0
If we subtract 3264 from 3571, we get 307.
Append the next digit (1) from the dividend to 307 and continue with: 3071 / 408

On to step 8:
408 goes into 3071 7 times with a remainder of 215.
Write down 7 as next digit of the result. 
Result so far: 105187.0
The remainder is 215 after subtracting 2856 from 3071.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Moving on to step 9:
408 goes into 2150 5 times with a remainder of 110.
Record the quotient 5 as the next digit in the result. 
Result so far: 105187.5
Deduct 2040 from 2150 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 10:
The number 408 fits into 1100 2 times, leaving a remainder of 284.
Use 2 as the next digit of our solution. 
Result so far: 105187.52
Deduct 816 from 1100 and we're left with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Step 11:
When dividing 2840 by 408, we get 6 with a remainder of 392.
The next digit of our result is 6. 
Result so far: 105187.526
The remainder is 392 after subtracting 2448 from 2840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Going ahead to step 12:
When dividing 3920 by 408, we get 9 with a remainder of 248.
Record the quotient 9 as the next digit in the result. 
Result so far: 105187.5269
If we subtract 3672 from 3920, we get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Going ahead to step 13:
408 goes into 2480 6 times with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 105187.52696
The remainder is 32 after subtracting 2448 from 2480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 14:
When dividing 320 by 408, we get 0 with a remainder of 320.
The number 0 becomes the next digit in our result. 
Result so far: 105187.52696
The remainder is 320 after subtracting 0 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 15:
When dividing 3200 by 408, we get 7 with a remainder of 344.
Use 7 as the next digit of our solution. 
Result so far: 105187.5269607
Subtracting 2856 from 3200 leaves us with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

On to step 16:
When dividing 3440 by 408, we get 8 with a remainder of 176.
The number 8 becomes the next digit in our result. 
Result so far: 105187.52696078
If we take 3264 away from 3440, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

After the division, we end up with 105187.52696078 and a remainder of 1.76e-07.
