We look at the division of 84401662 by 661 
Our goal is to divide 84401662 by 661.

Step 1:
If we divide 8 by 661, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 661

On to step 2:
When dividing 84 by 661, we get 0 with a remainder of 84.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Append the next digit (4) from the dividend to 84 and continue with: 844 / 661

Step 3:
661 goes into 844 1 times with a remainder of 183.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 661 from 844 leaves us with 183.
Fetch the next digit (0) from the dividend, attach it to 183 and continue: 1830 / 661

Moving on to step 4:
661 can be fit into 1830 2 times, resulting in a remainder of 508.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 1322 from 1830, we get 508.
Append the next digit (1) from the dividend to 508 and continue with: 5081 / 661

Step 5:
661 goes into 5081 7 times with a remainder of 454.
Use 7 as the next digit of our solution. 
Result so far: 127.0
If we take 4627 away from 5081, we end up with 454.
Take the next digit (6) from the dividend and append it to 454, then repeat: 4546 / 661

On to step 6:
When dividing 4546 by 661, we get 6 with a remainder of 580.
Use 6 as the next digit of our solution. 
Result so far: 1276.0
If we take 3966 away from 4546, we end up with 580.
Include the next digit (6) from the dividend after 580, then repeat: 5806 / 661

Advancing to step 7:
When dividing 5806 by 661, we get 8 with a remainder of 518.
The next digit of our result is 8. 
Result so far: 12768.0
Subtracting 5288 from 5806 leaves us with 518.
Append the next digit (2) from the dividend to 518 and continue with: 5182 / 661

On to step 8:
If we divide 5182 by 661, we get 7 and a remainder of 555.
Record the quotient 7 as the next digit in the result. 
Result so far: 127687.0
If we take 4627 away from 5182, we end up with 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Step 9:
5550 divided by 661 is 8 with a remainder of 262.
The next digit of our result is 8. 
Result so far: 127687.8
If we take 5288 away from 5550, we end up with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Moving on to step 10:
If we divide 2620 by 661, we get 3 and a remainder of 637.
The number 3 becomes the next digit in our result. 
Result so far: 127687.83
The remainder is 637 after subtracting 1983 from 2620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6370, and continue the process.

Advancing to step 11:
If we divide 6370 by 661, we get 9 and a remainder of 421.
Put 9 as the next digit of the answer. 
Result so far: 127687.839
If we take 5949 away from 6370, we end up with 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Let's proceed to step 12:
661 can be fit into 4210 6 times, resulting in a remainder of 244.
Use 6 as the next digit of our solution. 
Result so far: 127687.8396
If we subtract 3966 from 4210, we get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Advancing to step 13:
The number 661 fits into 2440 3 times, leaving a remainder of 457.
Use 3 as the next digit of our solution. 
Result so far: 127687.83963
Subtracting 1983 from 2440 leaves us with 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Let's proceed to step 14:
When dividing 4570 by 661, we get 6 with a remainder of 604.
The next digit of our result is 6. 
Result so far: 127687.839636
If we take 3966 away from 4570, we end up with 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

On to step 15:
If we divide 6040 by 661, we get 9 and a remainder of 91.
Put 9 as the next digit of the answer. 
Result so far: 127687.8396369
Subtract 5949 from 6040 to get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Advancing to step 16:
If we divide 910 by 661, we get 1 and a remainder of 249.
Put 1 as the next digit of the answer. 
Result so far: 127687.83963691
The remainder is 249 after subtracting 661 from 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

In conclusion, the division gives 127687.83963691 with a balance of 2.49e-07.
