We look at the division of 84320770 by 661 
Our goal is to divide 84320770 by 661.

Going ahead to step 1:
The number 661 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 661

Advancing to step 2:
If we divide 84 by 661, we get 0 and a remainder of 84.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Include the next digit (3) from the dividend after 84, then repeat: 843 / 661

Moving on to step 3:
If we divide 843 by 661, we get 1 and a remainder of 182.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 661 from 843, we get 182.
Grab the next digit (2) from the dividend, add it to 182, then carry on: 1822 / 661

Moving on to step 4:
661 goes into 1822 2 times with a remainder of 500.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 1322 from 1822 to get 500.
Fetch the next digit (0) from the dividend, attach it to 500 and continue: 5000 / 661

Going ahead to step 5:
When dividing 5000 by 661, we get 7 with a remainder of 373.
The number 7 becomes the next digit in our result. 
Result so far: 127.0
If we take 4627 away from 5000, we end up with 373.
Fetch the next digit (7) from the dividend, attach it to 373 and continue: 3737 / 661

Moving on to step 6:
3737 divided by 661 is 5 with a remainder of 432.
Record the quotient 5 as the next digit in the result. 
Result so far: 1275.0
Subtract 3305 from 3737 to get 432.
Grab the next digit (7) from the dividend, add it to 432, then carry on: 4327 / 661

On to step 7:
661 goes into 4327 6 times with a remainder of 361.
Put 6 as the next digit of the answer. 
Result so far: 12756.0
If we take 3966 away from 4327, we end up with 361.
Fetch the next digit (0) from the dividend, attach it to 361 and continue: 3610 / 661

Step 8:
661 goes into 3610 5 times with a remainder of 305.
The next digit of our result is 5. 
Result so far: 127565.0
Deduct 3305 from 3610 and we're left with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Moving on to step 9:
The number 661 fits into 3050 4 times, leaving a remainder of 406.
Put 4 as the next digit of the answer. 
Result so far: 127565.4
Deduct 2644 from 3050 and we're left with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Let's proceed to step 10:
The number 661 fits into 4060 6 times, leaving a remainder of 94.
The number 6 becomes the next digit in our result. 
Result so far: 127565.46
If we subtract 3966 from 4060, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 11:
The number 661 fits into 940 1 times, leaving a remainder of 279.
Write down 1 as next digit of the result. 
Result so far: 127565.461
Subtract 661 from 940 to get 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Going ahead to step 12:
The number 661 fits into 2790 4 times, leaving a remainder of 146.
Write down 4 as next digit of the result. 
Result so far: 127565.4614
Subtracting 2644 from 2790 leaves us with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Step 13:
1460 divided by 661 is 2 with a remainder of 138.
Put 2 as the next digit of the answer. 
Result so far: 127565.46142
If we take 1322 away from 1460, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Going ahead to step 14:
1380 divided by 661 is 2 with a remainder of 58.
The number 2 becomes the next digit in our result. 
Result so far: 127565.461422
If we subtract 1322 from 1380, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

After the division, we end up with 127565.461422 and a remainder of 5.8e-06.
