407160 ÷ 90 
We're looking to find how many times 90 goes into 407160.

Going ahead to step 1:
90 goes into 4 0 times with 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 (0) from the dividend, attach it to 4 and continue: 40 / 90

Moving on to step 2:
90 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Take the next digit (7) from the dividend and append it to 40, then repeat: 407 / 90

On to step 3:
The number 90 fits into 407 4 times, leaving a remainder of 47.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 360 away from 407, we end up with 47.
Take the next digit (1) from the dividend and append it to 47, then repeat: 471 / 90

Moving on to step 4:
The number 90 fits into 471 5 times, leaving a remainder of 21.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Deduct 450 from 471 and we're left with 21.
Bring next digit (6) of the dividend behind the 21 and repeat the process: 216 / 90

Moving on to step 5:
If we divide 216 by 90, we get 2 and a remainder of 36.
The next digit of our result is 2. 
Result so far: 452.0
If we subtract 180 from 216, we get 36.
Fetch the next digit (0) from the dividend, attach it to 36 and continue: 360 / 90

Advancing to step 6:
360 divided by 90 is 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 4524.0
Subtract 360 from 360 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.

On to step 7:
The number 90 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 4524.0
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.

Going ahead to step 8:
0 divided by 90 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4524.0
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.

Our division results in 4524.0 with a remaining 0.0.
