We divide 161936 by 4
We want to divide 161936 by 4.

On to step 1:
If we divide 1 by 4, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 4

Moving on to step 2:
16 divided by 4 is 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 16 from 16 leaves us with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 4

Advancing to step 3:
4 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 4

Going ahead to step 4:
19 divided by 4 is 4 with a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 404.0
If we subtract 16 from 19, we get 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 4

On to step 5:
If we divide 33 by 4, we get 8 and a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 4048.0
The remainder is 1 after subtracting 32 from 33.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 4

Moving on to step 6:
The number 4 fits into 16 4 times, leaving a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 40484.0
If we subtract 16 from 16, we 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.

Moving on to step 7:
4 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 40484.0
If we subtract 0 from 0, we 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.

Going ahead to step 8:
4 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 40484.0
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 40484.0, and the remainder is 0.0.
