Let's divide 8355902 by 661
We want to divide 8355902 by 661.

Going ahead to step 1:
If we divide 8 by 661, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 661

On to step 2:
83 divided by 661 is 0 with a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Include the next digit (5) from the dividend after 83, then repeat: 835 / 661

Moving on to step 3:
835 divided by 661 is 1 with a remainder of 174.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 661 from 835 to get 174.
Include the next digit (5) from the dividend after 174, then repeat: 1745 / 661

Step 4:
661 goes into 1745 2 times with a remainder of 423.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 423 after subtracting 1322 from 1745.
Append the next digit (9) from the dividend to 423 and continue with: 4239 / 661

Let's proceed to step 5:
When dividing 4239 by 661, we get 6 with a remainder of 273.
Record the quotient 6 as the next digit in the result. 
Result so far: 126.0
If we take 3966 away from 4239, we end up with 273.
Include the next digit (0) from the dividend after 273, then repeat: 2730 / 661

On to step 6:
661 goes into 2730 4 times with a remainder of 86.
The next digit of our result is 4. 
Result so far: 1264.0
The remainder is 86 after subtracting 2644 from 2730.
Fetch the next digit (2) from the dividend, attach it to 86 and continue: 862 / 661

Advancing to step 7:
661 can be fit into 862 1 times, resulting in a remainder of 201.
Put 1 as the next digit of the answer. 
Result so far: 12641.0
Subtracting 661 from 862 leaves us with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Step 8:
If we divide 2010 by 661, we get 3 and a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 12641.3
The remainder is 27 after subtracting 1983 from 2010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 9:
When dividing 270 by 661, we get 0 with a remainder of 270.
Put 0 as the next digit of the answer. 
Result so far: 12641.3
Subtract 0 from 270 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 10:
The number 661 fits into 2700 4 times, leaving a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 12641.304
Deduct 2644 from 2700 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 11:
The number 661 fits into 560 0 times, leaving a remainder of 560.
The next digit of our result is 0. 
Result so far: 12641.304
Deduct 0 from 560 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Moving on to step 12:
The number 661 fits into 5600 8 times, leaving a remainder of 312.
Put 8 as the next digit of the answer. 
Result so far: 12641.30408
Subtract 5288 from 5600 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Going ahead to step 13:
3120 divided by 661 is 4 with a remainder of 476.
Record the quotient 4 as the next digit in the result. 
Result so far: 12641.304084
If we subtract 2644 from 3120, we get 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Step 14:
When dividing 4760 by 661, we get 7 with a remainder of 133.
Put 7 as the next digit of the answer. 
Result so far: 12641.3040847
Deduct 4627 from 4760 and we're left with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Step 15:
661 goes into 1330 2 times with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 12641.30408472
The remainder is 8 after subtracting 1322 from 1330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 12641.30408472 with a balance of 8e-09.
