We divide 3867731 by 661
We want to divide 3867731 by 661.

On to step 1:
661 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 661

Going ahead to step 2:
If we divide 38 by 661, we get 0 and a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Grab the next digit (6) from the dividend, add it to 38, then carry on: 386 / 661

Advancing to step 3:
When dividing 386 by 661, we get 0 with a remainder of 386.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 386, we end up with 386.
Fetch the next digit (7) from the dividend, attach it to 386 and continue: 3867 / 661

Let's proceed to step 4:
661 can be fit into 3867 5 times, resulting in a remainder of 562.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 3305 from 3867 leaves us with 562.
Append the next digit (7) from the dividend to 562 and continue with: 5627 / 661

On to step 5:
If we divide 5627 by 661, we get 8 and a remainder of 339.
The number 8 becomes the next digit in our result. 
Result so far: 58.0
If we take 5288 away from 5627, we end up with 339.
Take the next digit (3) from the dividend and append it to 339, then repeat: 3393 / 661

Going ahead to step 6:
661 goes into 3393 5 times with a remainder of 88.
The next digit of our result is 5. 
Result so far: 585.0
If we take 3305 away from 3393, we end up with 88.
Append the next digit (1) from the dividend to 88 and continue with: 881 / 661

On to step 7:
The number 661 fits into 881 1 times, leaving a remainder of 220.
Write down 1 as next digit of the result. 
Result so far: 5851.0
If we take 661 away from 881, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 8:
661 goes into 2200 3 times with a remainder of 217.
The number 3 becomes the next digit in our result. 
Result so far: 5851.3
If we take 1983 away from 2200, we end up with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Going ahead to step 9:
The number 661 fits into 2170 3 times, leaving a remainder of 187.
Use 3 as the next digit of our solution. 
Result so far: 5851.33
Deduct 1983 from 2170 and we're left with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

The quotient of the division is 5851.33, and the remainder is 0.187.
