We divide 85047020 by 639
We want to divide 85047020 by 639.

Let's proceed to step 1:
8 divided by 639 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 639

Advancing to step 2:
639 goes into 85 0 times with a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 85 leaves us with 85.
Grab the next digit (0) from the dividend, add it to 85, then carry on: 850 / 639

Going ahead to step 3:
639 goes into 850 1 times with a remainder of 211.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 639 from 850 to get 211.
Append the next digit (4) from the dividend to 211 and continue with: 2114 / 639

Advancing to step 4:
2114 divided by 639 is 3 with a remainder of 197.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 197 after subtracting 1917 from 2114.
Append the next digit (7) from the dividend to 197 and continue with: 1977 / 639

On to step 5:
639 goes into 1977 3 times with a remainder of 60.
Use 3 as the next digit of our solution. 
Result so far: 133.0
If we subtract 1917 from 1977, we get 60.
Fetch the next digit (0) from the dividend, attach it to 60 and continue: 600 / 639

Going ahead to step 6:
639 can be fit into 600 0 times, resulting in a remainder of 600.
The number 0 becomes the next digit in our result. 
Result so far: 1330.0
Deduct 0 from 600 and we're left with 600.
Bring next digit (2) of the dividend behind the 600 and repeat the process: 6002 / 639

Moving on to step 7:
639 goes into 6002 9 times with a remainder of 251.
Use 9 as the next digit of our solution. 
Result so far: 13309.0
Subtract 5751 from 6002 to get 251.
Grab the next digit (0) from the dividend, add it to 251, then carry on: 2510 / 639

Moving on to step 8:
If we divide 2510 by 639, we get 3 and a remainder of 593.
Use 3 as the next digit of our solution. 
Result so far: 133093.0
The remainder is 593 after subtracting 1917 from 2510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5930, and continue the process.

Going ahead to step 9:
5930 divided by 639 is 9 with a remainder of 179.
Use 9 as the next digit of our solution. 
Result so far: 133093.9
Subtracting 5751 from 5930 leaves us with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Going ahead to step 10:
1790 divided by 639 is 2 with a remainder of 512.
Write down 2 as next digit of the result. 
Result so far: 133093.92
Subtract 1278 from 1790 to get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Going ahead to step 11:
639 can be fit into 5120 8 times, resulting in a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 133093.928
Subtracting 5112 from 5120 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
The number 639 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 133093.928
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 13:
The number 639 fits into 800 1 times, leaving a remainder of 161.
Put 1 as the next digit of the answer. 
Result so far: 133093.92801
If we subtract 639 from 800, we get 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

On to step 14:
When dividing 1610 by 639, we get 2 with a remainder of 332.
Put 2 as the next digit of the answer. 
Result so far: 133093.928012
Deduct 1278 from 1610 and we're left with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Moving on to step 15:
3320 divided by 639 is 5 with a remainder of 125.
The number 5 becomes the next digit in our result. 
Result so far: 133093.9280125
Deduct 3195 from 3320 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Step 16:
1250 divided by 639 is 1 with a remainder of 611.
Use 1 as the next digit of our solution. 
Result so far: 133093.92801251
The remainder is 611 after subtracting 639 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6110, and continue the process.

After the division, we end up with 133093.92801251 and a remainder of 6.11e-07.
