30625181 divided by 661 
We want to divide 30625181 by 661.

On to step 1:
The number 661 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 661

Going ahead to step 2:
661 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Append the next digit (6) from the dividend to 30 and continue with: 306 / 661

Advancing to step 3:
When dividing 306 by 661, we get 0 with a remainder of 306.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 306 after subtracting 0 from 306.
Include the next digit (2) from the dividend after 306, then repeat: 3062 / 661

Let's proceed to step 4:
661 goes into 3062 4 times with a remainder of 418.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 2644 from 3062 leaves us with 418.
Include the next digit (5) from the dividend after 418, then repeat: 4185 / 661

Let's proceed to step 5:
661 goes into 4185 6 times with a remainder of 219.
The next digit of our result is 6. 
Result so far: 46.0
The remainder is 219 after subtracting 3966 from 4185.
Take the next digit (1) from the dividend and append it to 219, then repeat: 2191 / 661

Advancing to step 6:
When dividing 2191 by 661, we get 3 with a remainder of 208.
Put 3 as the next digit of the answer. 
Result so far: 463.0
The remainder is 208 after subtracting 1983 from 2191.
Append the next digit (8) from the dividend to 208 and continue with: 2088 / 661

Advancing to step 7:
The number 661 fits into 2088 3 times, leaving a remainder of 105.
Use 3 as the next digit of our solution. 
Result so far: 4633.0
The remainder is 105 after subtracting 1983 from 2088.
Grab the next digit (1) from the dividend, add it to 105, then carry on: 1051 / 661

Step 8:
If we divide 1051 by 661, we get 1 and a remainder of 390.
Use 1 as the next digit of our solution. 
Result so far: 46331.0
If we take 661 away from 1051, we end up with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 9:
When dividing 3900 by 661, we get 5 with a remainder of 595.
Use 5 as the next digit of our solution. 
Result so far: 46331.5
If we take 3305 away from 3900, we end up with 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Advancing to step 10:
5950 divided by 661 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 46331.59
Deduct 5949 from 5950 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 11:
661 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 46331.59
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
661 goes into 100 0 times with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 46331.59
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The quotient of the division is 46331.59, and the remainder is 0.001.
