87149344 ÷ 661 
We want to divide 87149344 by 661.

Moving on to step 1:
661 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 661

Step 2:
The number 661 fits into 87 0 times, leaving a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Bring next digit (1) of the dividend behind the 87 and repeat the process: 871 / 661

On to step 3:
The number 661 fits into 871 1 times, leaving a remainder of 210.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 661 from 871 to get 210.
Fetch the next digit (4) from the dividend, attach it to 210 and continue: 2104 / 661

Step 4:
If we divide 2104 by 661, we get 3 and a remainder of 121.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we take 1983 away from 2104, we end up with 121.
Bring next digit (9) of the dividend behind the 121 and repeat the process: 1219 / 661

Going ahead to step 5:
The number 661 fits into 1219 1 times, leaving a remainder of 558.
Write down 1 as next digit of the result. 
Result so far: 131.0
Deduct 661 from 1219 and we're left with 558.
Grab the next digit (3) from the dividend, add it to 558, then carry on: 5583 / 661

Let's proceed to step 6:
When dividing 5583 by 661, we get 8 with a remainder of 295.
The next digit of our result is 8. 
Result so far: 1318.0
If we subtract 5288 from 5583, we get 295.
Include the next digit (4) from the dividend after 295, then repeat: 2954 / 661

Let's proceed to step 7:
661 goes into 2954 4 times with a remainder of 310.
Write down 4 as next digit of the result. 
Result so far: 13184.0
The remainder is 310 after subtracting 2644 from 2954.
Take the next digit (4) from the dividend and append it to 310, then repeat: 3104 / 661

Let's proceed to step 8:
3104 divided by 661 is 4 with a remainder of 460.
Write down 4 as next digit of the result. 
Result so far: 131844.0
If we take 2644 away from 3104, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

On to step 9:
661 can be fit into 4600 6 times, resulting in a remainder of 634.
Put 6 as the next digit of the answer. 
Result so far: 131844.6
Subtracting 3966 from 4600 leaves us with 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

Let's proceed to step 10:
6340 divided by 661 is 9 with a remainder of 391.
Use 9 as the next digit of our solution. 
Result so far: 131844.69
If we take 5949 away from 6340, we end up with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Advancing to step 11:
If we divide 3910 by 661, we get 5 and a remainder of 605.
Record the quotient 5 as the next digit in the result. 
Result so far: 131844.695
Subtract 3305 from 3910 to get 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

On to step 12:
661 can be fit into 6050 9 times, resulting in a remainder of 101.
Record the quotient 9 as the next digit in the result. 
Result so far: 131844.6959
Deduct 5949 from 6050 and we're left with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Let's proceed to step 13:
661 can be fit into 1010 1 times, resulting in a remainder of 349.
Record the quotient 1 as the next digit in the result. 
Result so far: 131844.69591
The remainder is 349 after subtracting 661 from 1010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Going ahead to step 14:
If we divide 3490 by 661, we get 5 and a remainder of 185.
Write down 5 as next digit of the result. 
Result so far: 131844.695915
Subtract 3305 from 3490 to get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Going ahead to step 15:
1850 divided by 661 is 2 with a remainder of 528.
Put 2 as the next digit of the answer. 
Result so far: 131844.6959152
If we subtract 1322 from 1850, we get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Moving on to step 16:
5280 divided by 661 is 7 with a remainder of 653.
The next digit of our result is 7. 
Result so far: 131844.69591527
Deduct 4627 from 5280 and we're left with 653.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6530, and continue the process.

In conclusion, the division gives 131844.69591527 with a balance of 6.53e-07.
