84113770 divided by 639 
Our goal is to divide 84113770 by 639.

Moving on to step 1:
If we divide 8 by 639, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 639

Let's proceed to step 2:
84 divided by 639 is 0 with a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 84, we end up with 84.
Append the next digit (1) from the dividend to 84 and continue with: 841 / 639

Going ahead to step 3:
841 divided by 639 is 1 with a remainder of 202.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 639 from 841, we get 202.
Include the next digit (1) from the dividend after 202, then repeat: 2021 / 639

On to step 4:
The number 639 fits into 2021 3 times, leaving a remainder of 104.
The next digit of our result is 3. 
Result so far: 13.0
The remainder is 104 after subtracting 1917 from 2021.
Append the next digit (3) from the dividend to 104 and continue with: 1043 / 639

On to step 5:
If we divide 1043 by 639, we get 1 and a remainder of 404.
Record the quotient 1 as the next digit in the result. 
Result so far: 131.0
Deduct 639 from 1043 and we're left with 404.
Grab the next digit (7) from the dividend, add it to 404, then carry on: 4047 / 639

On to step 6:
The number 639 fits into 4047 6 times, leaving a remainder of 213.
Use 6 as the next digit of our solution. 
Result so far: 1316.0
Deduct 3834 from 4047 and we're left with 213.
Include the next digit (7) from the dividend after 213, then repeat: 2137 / 639

Moving on to step 7:
639 can be fit into 2137 3 times, resulting in a remainder of 220.
The next digit of our result is 3. 
Result so far: 13163.0
The remainder is 220 after subtracting 1917 from 2137.
Append the next digit (0) from the dividend to 220 and continue with: 2200 / 639

Going ahead to step 8:
If we divide 2200 by 639, we get 3 and a remainder of 283.
Use 3 as the next digit of our solution. 
Result so far: 131633.0
If we take 1917 away from 2200, we end up with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Let's proceed to step 9:
2830 divided by 639 is 4 with a remainder of 274.
Put 4 as the next digit of the answer. 
Result so far: 131633.4
If we take 2556 away from 2830, we end up with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Going ahead to step 10:
2740 divided by 639 is 4 with a remainder of 184.
Put 4 as the next digit of the answer. 
Result so far: 131633.44
Deduct 2556 from 2740 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

In conclusion, the division gives 131633.44 with a balance of 0.184.
