87447768 divided by 661 
We want to figure out the number of times 87447768 can be divided by 661.

On to step 1:
661 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 661

Let's proceed to step 2:
661 can be fit into 87 0 times, resulting in a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Append the next digit (4) from the dividend to 87 and continue with: 874 / 661

Moving on to step 3:
When dividing 874 by 661, we get 1 with a remainder of 213.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 661 from 874 and we're left with 213.
Bring next digit (4) of the dividend behind the 213 and repeat the process: 2134 / 661

Step 4:
If we divide 2134 by 661, we get 3 and a remainder of 151.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 1983 from 2134, we get 151.
Fetch the next digit (7) from the dividend, attach it to 151 and continue: 1517 / 661

Moving on to step 5:
If we divide 1517 by 661, we get 2 and a remainder of 195.
The number 2 becomes the next digit in our result. 
Result so far: 132.0
Subtracting 1322 from 1517 leaves us with 195.
Fetch the next digit (7) from the dividend, attach it to 195 and continue: 1957 / 661

Moving on to step 6:
If we divide 1957 by 661, we get 2 and a remainder of 635.
The next digit of our result is 2. 
Result so far: 1322.0
Subtracting 1322 from 1957 leaves us with 635.
Take the next digit (6) from the dividend and append it to 635, then repeat: 6356 / 661

Advancing to step 7:
The number 661 fits into 6356 9 times, leaving a remainder of 407.
The next digit of our result is 9. 
Result so far: 13229.0
The remainder is 407 after subtracting 5949 from 6356.
Fetch the next digit (8) from the dividend, attach it to 407 and continue: 4078 / 661

Step 8:
4078 divided by 661 is 6 with a remainder of 112.
The number 6 becomes the next digit in our result. 
Result so far: 132296.0
Subtracting 3966 from 4078 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 9:
661 goes into 1120 1 times with a remainder of 459.
The next digit of our result is 1. 
Result so far: 132296.1
Subtract 661 from 1120 to get 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

Let's proceed to step 10:
When dividing 4590 by 661, we get 6 with a remainder of 624.
Use 6 as the next digit of our solution. 
Result so far: 132296.16
If we take 3966 away from 4590, we end up with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Let's proceed to step 11:
661 goes into 6240 9 times with a remainder of 291.
Use 9 as the next digit of our solution. 
Result so far: 132296.169
Deduct 5949 from 6240 and we're left with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Step 12:
The number 661 fits into 2910 4 times, leaving a remainder of 266.
Put 4 as the next digit of the answer. 
Result so far: 132296.1694
Deduct 2644 from 2910 and we're left with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Step 13:
If we divide 2660 by 661, we get 4 and a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 132296.16944
The remainder is 16 after subtracting 2644 from 2660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 132296.16944 with a balance of 1.6e-05.
