16669673 ÷ 40 
Let's see how many times 40 fits into 16669673.

Going ahead to step 1:
When dividing 1 by 40, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 40

Let's proceed to step 2:
16 divided by 40 is 0 with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Bring next digit (6) of the dividend behind the 16 and repeat the process: 166 / 40

Step 3:
40 goes into 166 4 times with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 6 after subtracting 160 from 166.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 40

Moving on to step 4:
40 can be fit into 66 1 times, resulting in a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 41.0
If we subtract 40 from 66, we get 26.
Append the next digit (9) from the dividend to 26 and continue with: 269 / 40

Step 5:
The number 40 fits into 269 6 times, leaving a remainder of 29.
Put 6 as the next digit of the answer. 
Result so far: 416.0
The remainder is 29 after subtracting 240 from 269.
Append the next digit (6) from the dividend to 29 and continue with: 296 / 40

Going ahead to step 6:
40 can be fit into 296 7 times, resulting in a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 4167.0
Deduct 280 from 296 and we're left with 16.
Append the next digit (7) from the dividend to 16 and continue with: 167 / 40

Let's proceed to step 7:
The number 40 fits into 167 4 times, leaving a remainder of 7.
The next digit of our result is 4. 
Result so far: 41674.0
Deduct 160 from 167 and we're left with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 40

Step 8:
73 divided by 40 is 1 with a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 416741.0
If we subtract 40 from 73, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 9:
40 goes into 330 8 times with a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 416741.8
Deduct 320 from 330 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
The number 40 fits into 100 2 times, leaving a remainder of 20.
The next digit of our result is 2. 
Result so far: 416741.82
Deduct 80 from 100 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 11:
When dividing 200 by 40, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 416741.825
Subtracting 200 from 200 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 12:
When dividing 0 by 40, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 416741.825
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 13:
40 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 416741.825
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 416741.825, and the remainder is 0.0.
