801661 ÷ 7 
We want to figure out the number of times 801661 can be divided by 7.

Step 1:
7 can be fit into 8 1 times, resulting in a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 7 from 8, we get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 7

Let's proceed to step 2:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 7 from 10 and we're left with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 7

Step 3:
31 divided by 7 is 4 with a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 114.0
Subtracting 28 from 31 leaves us with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 7

Advancing to step 4:
7 goes into 36 5 times with a remainder of 1.
The next digit of our result is 5. 
Result so far: 1145.0
Subtract 35 from 36 to get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 7

On to step 5:
16 divided by 7 is 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 11452.0
Subtracting 14 from 16 leaves us with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 7

Moving on to step 6:
7 can be fit into 21 3 times, resulting in a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 114523.0
Subtract 21 from 21 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
7 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 114523.0
Subtracting 0 from 0 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.

Let's proceed to step 8:
If we divide 0 by 7, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 114523.0
If we take 0 away from 0, we end up 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.

The quotient of the division is 114523.0, and the remainder is 0.0.
