We divide 75398586 by 408
We want to divide 75398586 by 408.

Let's proceed to step 1:
The number 408 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 408

Advancing to step 2:
75 divided by 408 is 0 with a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 75 leaves us with 75.
Bring next digit (3) of the dividend behind the 75 and repeat the process: 753 / 408

Moving on to step 3:
408 can be fit into 753 1 times, resulting in a remainder of 345.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 408 from 753 and we're left with 345.
Take the next digit (9) from the dividend and append it to 345, then repeat: 3459 / 408

Step 4:
3459 divided by 408 is 8 with a remainder of 195.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Deduct 3264 from 3459 and we're left with 195.
Append the next digit (8) from the dividend to 195 and continue with: 1958 / 408

Moving on to step 5:
1958 divided by 408 is 4 with a remainder of 326.
Put 4 as the next digit of the answer. 
Result so far: 184.0
If we take 1632 away from 1958, we end up with 326.
Take the next digit (5) from the dividend and append it to 326, then repeat: 3265 / 408

Moving on to step 6:
If we divide 3265 by 408, we get 8 and a remainder of 1.
The next digit of our result is 8. 
Result so far: 1848.0
Deduct 3264 from 3265 and we're left with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 408

Going ahead to step 7:
408 can be fit into 18 0 times, resulting in a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 18480.0
Subtract 0 from 18 to get 18.
Bring next digit (6) of the dividend behind the 18 and repeat the process: 186 / 408

Going ahead to step 8:
186 divided by 408 is 0 with a remainder of 186.
Write down 0 as next digit of the result. 
Result so far: 184800.0
Subtract 0 from 186 to get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Going ahead to step 9:
408 can be fit into 1860 4 times, resulting in a remainder of 228.
The number 4 becomes the next digit in our result. 
Result so far: 184800.4
If we take 1632 away from 1860, we end up with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Advancing to step 10:
When dividing 2280 by 408, we get 5 with a remainder of 240.
The next digit of our result is 5. 
Result so far: 184800.45
Subtract 2040 from 2280 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 11:
If we divide 2400 by 408, we get 5 and a remainder of 360.
Record the quotient 5 as the next digit in the result. 
Result so far: 184800.455
If we subtract 2040 from 2400, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

The quotient of the division is 184800.455, and the remainder is 0.036.
