We look at the division of 161609 by 7 
Our goal is to divide 161609 by 7.

On to step 1:
The number 7 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 7

Going ahead to step 2:
The number 7 fits into 16 2 times, leaving a remainder of 2.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 14 from 16, we get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 7

Going ahead to step 3:
If we divide 21 by 7, we get 3 and a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Deduct 21 from 21 and we're left with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 7

Moving on to step 4:
When dividing 6 by 7, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 230.0
Subtract 0 from 6 to get 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 7

Moving on to step 5:
60 divided by 7 is 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 2308.0
If we subtract 56 from 60, we get 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 7

Going ahead to step 6:
49 divided by 7 is 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 23087.0
If we take 49 away from 49, 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.

Going ahead to step 7:
When dividing 0 by 7, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 23087.0
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.

Advancing to step 8:
7 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 23087.0
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.

After the division, we end up with 23087.0 and a remainder of 0.0.
