87629480 divided by 661 
We want to divide 87629480 by 661.

Going ahead to step 1:
8 divided by 661 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 661

Step 2:
The number 661 fits into 87 0 times, leaving a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Include the next digit (6) from the dividend after 87, then repeat: 876 / 661

Going ahead to step 3:
661 goes into 876 1 times with a remainder of 215.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 661 from 876 and we're left with 215.
Append the next digit (2) from the dividend to 215 and continue with: 2152 / 661

Step 4:
2152 divided by 661 is 3 with a remainder of 169.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 1983 from 2152 and we're left with 169.
Take the next digit (9) from the dividend and append it to 169, then repeat: 1699 / 661

Moving on to step 5:
661 can be fit into 1699 2 times, resulting in a remainder of 377.
Record the quotient 2 as the next digit in the result. 
Result so far: 132.0
The remainder is 377 after subtracting 1322 from 1699.
Grab the next digit (4) from the dividend, add it to 377, then carry on: 3774 / 661

On to step 6:
3774 divided by 661 is 5 with a remainder of 469.
Write down 5 as next digit of the result. 
Result so far: 1325.0
If we subtract 3305 from 3774, we get 469.
Append the next digit (8) from the dividend to 469 and continue with: 4698 / 661

Let's proceed to step 7:
The number 661 fits into 4698 7 times, leaving a remainder of 71.
The number 7 becomes the next digit in our result. 
Result so far: 13257.0
If we take 4627 away from 4698, we end up with 71.
Append the next digit (0) from the dividend to 71 and continue with: 710 / 661

Going ahead to step 8:
When dividing 710 by 661, we get 1 with a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 132571.0
Subtract 661 from 710 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 9:
The number 661 fits into 490 0 times, leaving a remainder of 490.
The number 0 becomes the next digit in our result. 
Result so far: 132571.0
If we take 0 away from 490, we end up with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Moving on to step 10:
If we divide 4900 by 661, we get 7 and a remainder of 273.
The number 7 becomes the next digit in our result. 
Result so far: 132571.07
Subtracting 4627 from 4900 leaves us with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

On to step 11:
If we divide 2730 by 661, we get 4 and a remainder of 86.
The number 4 becomes the next digit in our result. 
Result so far: 132571.074
The remainder is 86 after subtracting 2644 from 2730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 12:
If we divide 860 by 661, we get 1 and a remainder of 199.
The number 1 becomes the next digit in our result. 
Result so far: 132571.0741
Subtract 661 from 860 to get 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Moving on to step 13:
When dividing 1990 by 661, we get 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 132571.07413
Subtract 1983 from 1990 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 14:
If we divide 70 by 661, we get 0 and a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 132571.07413
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 15:
The number 661 fits into 700 1 times, leaving a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 132571.0741301
Subtracting 661 from 700 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 16:
390 divided by 661 is 0 with a remainder of 390.
Use 0 as the next digit of our solution. 
Result so far: 132571.0741301
The remainder is 390 after subtracting 0 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

The final result is 132571.0741301 with a remainder of 3.9e-07.
