Let's divide 42647861 by 661
We want to figure out the number of times 42647861 can be divided by 661.

Let's proceed to step 1:
The number 661 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 661

Moving on to step 2:
The number 661 fits into 42 0 times, leaving a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Include the next digit (6) from the dividend after 42, then repeat: 426 / 661

Step 3:
If we divide 426 by 661, we get 0 and a remainder of 426.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 426 leaves us with 426.
Fetch the next digit (4) from the dividend, attach it to 426 and continue: 4264 / 661

Going ahead to step 4:
661 goes into 4264 6 times with a remainder of 298.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 3966 from 4264 and we're left with 298.
Fetch the next digit (7) from the dividend, attach it to 298 and continue: 2987 / 661

Moving on to step 5:
2987 divided by 661 is 4 with a remainder of 343.
Use 4 as the next digit of our solution. 
Result so far: 64.0
Deduct 2644 from 2987 and we're left with 343.
Bring next digit (8) of the dividend behind the 343 and repeat the process: 3438 / 661

Let's proceed to step 6:
When dividing 3438 by 661, we get 5 with a remainder of 133.
The number 5 becomes the next digit in our result. 
Result so far: 645.0
Subtracting 3305 from 3438 leaves us with 133.
Take the next digit (6) from the dividend and append it to 133, then repeat: 1336 / 661

Going ahead to step 7:
661 goes into 1336 2 times with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 6452.0
The remainder is 14 after subtracting 1322 from 1336.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 661

Going ahead to step 8:
When dividing 141 by 661, we get 0 with a remainder of 141.
The number 0 becomes the next digit in our result. 
Result so far: 64520.0
Subtracting 0 from 141 leaves us with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Advancing to step 9:
1410 divided by 661 is 2 with a remainder of 88.
The number 2 becomes the next digit in our result. 
Result so far: 64520.2
The remainder is 88 after subtracting 1322 from 1410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 10:
When dividing 880 by 661, we get 1 with a remainder of 219.
The number 1 becomes the next digit in our result. 
Result so far: 64520.21
Subtracting 661 from 880 leaves us with 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Step 11:
661 goes into 2190 3 times with a remainder of 207.
Record the quotient 3 as the next digit in the result. 
Result so far: 64520.213
If we take 1983 away from 2190, we end up with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Going ahead to step 12:
661 goes into 2070 3 times with a remainder of 87.
The next digit of our result is 3. 
Result so far: 64520.2133
Subtracting 1983 from 2070 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

The final result is 64520.2133 with a remainder of 0.00087.
