We're dividing 69187181 by 639 
We want to figure out the number of times 69187181 can be divided by 639.

Step 1:
The number 639 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 639

On to step 2:
The number 639 fits into 69 0 times, leaving a remainder of 69.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 69, we end up with 69.
Take the next digit (1) from the dividend and append it to 69, then repeat: 691 / 639

Moving on to step 3:
691 divided by 639 is 1 with a remainder of 52.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 639 from 691 and we're left with 52.
Include the next digit (8) from the dividend after 52, then repeat: 528 / 639

Going ahead to step 4:
639 goes into 528 0 times with a remainder of 528.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 528, we end up with 528.
Grab the next digit (7) from the dividend, add it to 528, then carry on: 5287 / 639

On to step 5:
639 goes into 5287 8 times with a remainder of 175.
Put 8 as the next digit of the answer. 
Result so far: 108.0
If we subtract 5112 from 5287, we get 175.
Grab the next digit (1) from the dividend, add it to 175, then carry on: 1751 / 639

Moving on to step 6:
The number 639 fits into 1751 2 times, leaving a remainder of 473.
Record the quotient 2 as the next digit in the result. 
Result so far: 1082.0
Subtracting 1278 from 1751 leaves us with 473.
Fetch the next digit (8) from the dividend, attach it to 473 and continue: 4738 / 639

Step 7:
639 goes into 4738 7 times with a remainder of 265.
The number 7 becomes the next digit in our result. 
Result so far: 10827.0
Deduct 4473 from 4738 and we're left with 265.
Fetch the next digit (1) from the dividend, attach it to 265 and continue: 2651 / 639

Going ahead to step 8:
639 goes into 2651 4 times with a remainder of 95.
The number 4 becomes the next digit in our result. 
Result so far: 108274.0
If we subtract 2556 from 2651, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Advancing to step 9:
If we divide 950 by 639, we get 1 and a remainder of 311.
Use 1 as the next digit of our solution. 
Result so far: 108274.1
Deduct 639 from 950 and we're left with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

On to step 10:
If we divide 3110 by 639, we get 4 and a remainder of 554.
The number 4 becomes the next digit in our result. 
Result so far: 108274.14
Deduct 2556 from 3110 and we're left with 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Advancing to step 11:
If we divide 5540 by 639, we get 8 and a remainder of 428.
The next digit of our result is 8. 
Result so far: 108274.148
If we take 5112 away from 5540, we end up with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Advancing to step 12:
The number 639 fits into 4280 6 times, leaving a remainder of 446.
Record the quotient 6 as the next digit in the result. 
Result so far: 108274.1486
Subtracting 3834 from 4280 leaves us with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Advancing to step 13:
When dividing 4460 by 639, we get 6 with a remainder of 626.
Use 6 as the next digit of our solution. 
Result so far: 108274.14866
Deduct 3834 from 4460 and we're left with 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

The quotient of the division is 108274.14866, and the remainder is 0.000626.
