We divide 85378195 by 639
We want to figure out the number of times 85378195 can be divided by 639.

Going ahead to step 1:
8 divided by 639 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 639

Step 2:
85 divided by 639 is 0 with a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Grab the next digit (3) from the dividend, add it to 85, then carry on: 853 / 639

Step 3:
639 goes into 853 1 times with a remainder of 214.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 639 from 853 and we're left with 214.
Include the next digit (7) from the dividend after 214, then repeat: 2147 / 639

Advancing to step 4:
If we divide 2147 by 639, we get 3 and a remainder of 230.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we take 1917 away from 2147, we end up with 230.
Bring next digit (8) of the dividend behind the 230 and repeat the process: 2308 / 639

Going ahead to step 5:
2308 divided by 639 is 3 with a remainder of 391.
Record the quotient 3 as the next digit in the result. 
Result so far: 133.0
Subtracting 1917 from 2308 leaves us with 391.
Bring next digit (1) of the dividend behind the 391 and repeat the process: 3911 / 639

Step 6:
639 goes into 3911 6 times with a remainder of 77.
Put 6 as the next digit of the answer. 
Result so far: 1336.0
If we take 3834 away from 3911, we end up with 77.
Bring next digit (9) of the dividend behind the 77 and repeat the process: 779 / 639

Going ahead to step 7:
779 divided by 639 is 1 with a remainder of 140.
The next digit of our result is 1. 
Result so far: 13361.0
Deduct 639 from 779 and we're left with 140.
Take the next digit (5) from the dividend and append it to 140, then repeat: 1405 / 639

Step 8:
639 goes into 1405 2 times with a remainder of 127.
Write down 2 as next digit of the result. 
Result so far: 133612.0
Subtracting 1278 from 1405 leaves us with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Advancing to step 9:
1270 divided by 639 is 1 with a remainder of 631.
The number 1 becomes the next digit in our result. 
Result so far: 133612.1
Subtract 639 from 1270 to get 631.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6310, and continue the process.

On to step 10:
When dividing 6310 by 639, we get 9 with a remainder of 559.
The number 9 becomes the next digit in our result. 
Result so far: 133612.19
Deduct 5751 from 6310 and we're left with 559.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5590, and continue the process.

Going ahead to step 11:
639 can be fit into 5590 8 times, resulting in a remainder of 478.
Put 8 as the next digit of the answer. 
Result so far: 133612.198
If we subtract 5112 from 5590, we get 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

On to step 12:
4780 divided by 639 is 7 with a remainder of 307.
Record the quotient 7 as the next digit in the result. 
Result so far: 133612.1987
If we subtract 4473 from 4780, we get 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Going ahead to step 13:
639 goes into 3070 4 times with a remainder of 514.
The number 4 becomes the next digit in our result. 
Result so far: 133612.19874
Subtracting 2556 from 3070 leaves us with 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Going ahead to step 14:
If we divide 5140 by 639, we get 8 and a remainder of 28.
The next digit of our result is 8. 
Result so far: 133612.198748
Subtracting 5112 from 5140 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 15:
639 goes into 280 0 times with a remainder of 280.
The next digit of our result is 0. 
Result so far: 133612.198748
Deduct 0 from 280 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 16:
639 can be fit into 2800 4 times, resulting in a remainder of 244.
The next digit of our result is 4. 
Result so far: 133612.19874804
If we subtract 2556 from 2800, 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.

Our division results in 133612.19874804 with a remaining 2.44e-07.
