We divide 86021734 by 661
Let's see how many times 661 fits into 86021734.

Going ahead to step 1:
8 divided by 661 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 661

Advancing to step 2:
When dividing 86 by 661, we get 0 with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Grab the next digit (0) from the dividend, add it to 86, then carry on: 860 / 661

Step 3:
When dividing 860 by 661, we get 1 with a remainder of 199.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 199 after subtracting 661 from 860.
Grab the next digit (2) from the dividend, add it to 199, then carry on: 1992 / 661

Moving on to step 4:
When dividing 1992 by 661, we get 3 with a remainder of 9.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 1983 from 1992 to get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 661

Let's proceed to step 5:
661 goes into 91 0 times with a remainder of 91.
The next digit of our result is 0. 
Result so far: 130.0
If we take 0 away from 91, we end up with 91.
Fetch the next digit (7) from the dividend, attach it to 91 and continue: 917 / 661

On to step 6:
917 divided by 661 is 1 with a remainder of 256.
Write down 1 as next digit of the result. 
Result so far: 1301.0
Subtracting 661 from 917 leaves us with 256.
Include the next digit (3) from the dividend after 256, then repeat: 2563 / 661

Step 7:
661 goes into 2563 3 times with a remainder of 580.
Put 3 as the next digit of the answer. 
Result so far: 13013.0
Deduct 1983 from 2563 and we're left with 580.
Grab the next digit (4) from the dividend, add it to 580, then carry on: 5804 / 661

Advancing to step 8:
661 goes into 5804 8 times with a remainder of 516.
The next digit of our result is 8. 
Result so far: 130138.0
If we subtract 5288 from 5804, we get 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Step 9:
661 can be fit into 5160 7 times, resulting in a remainder of 533.
Use 7 as the next digit of our solution. 
Result so far: 130138.7
If we subtract 4627 from 5160, we get 533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

On to step 10:
The number 661 fits into 5330 8 times, leaving a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 130138.78
The remainder is 42 after subtracting 5288 from 5330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 11:
The number 661 fits into 420 0 times, leaving a remainder of 420.
The number 0 becomes the next digit in our result. 
Result so far: 130138.78
Deduct 0 from 420 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Going ahead to step 12:
If we divide 4200 by 661, we get 6 and a remainder of 234.
Use 6 as the next digit of our solution. 
Result so far: 130138.7806
If we subtract 3966 from 4200, we get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Going ahead to step 13:
2340 divided by 661 is 3 with a remainder of 357.
The next digit of our result is 3. 
Result so far: 130138.78063
Deduct 1983 from 2340 and we're left with 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

On to step 14:
3570 divided by 661 is 5 with a remainder of 265.
The next digit of our result is 5. 
Result so far: 130138.780635
Subtract 3305 from 3570 to get 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Advancing to step 15:
The number 661 fits into 2650 4 times, leaving a remainder of 6.
The next digit of our result is 4. 
Result so far: 130138.7806354
Subtracting 2644 from 2650 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 16:
The number 661 fits into 60 0 times, leaving a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 130138.7806354
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 130138.7806354 with a remainder of 6e-08.
