Let's divide 67638380 by 641
We want to figure out the number of times 67638380 can be divided by 641.

Step 1:
641 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 641

Advancing to step 2:
When dividing 67 by 641, we get 0 with a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 67 leaves us with 67.
Take the next digit (6) from the dividend and append it to 67, then repeat: 676 / 641

Going ahead to step 3:
641 goes into 676 1 times with a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 641 away from 676, we end up with 35.
Fetch the next digit (3) from the dividend, attach it to 35 and continue: 353 / 641

Moving on to step 4:
When dividing 353 by 641, we get 0 with a remainder of 353.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 353, we end up with 353.
Grab the next digit (8) from the dividend, add it to 353, then carry on: 3538 / 641

Moving on to step 5:
When dividing 3538 by 641, we get 5 with a remainder of 333.
The next digit of our result is 5. 
Result so far: 105.0
Subtracting 3205 from 3538 leaves us with 333.
Append the next digit (3) from the dividend to 333 and continue with: 3333 / 641

Going ahead to step 6:
If we divide 3333 by 641, we get 5 and a remainder of 128.
The number 5 becomes the next digit in our result. 
Result so far: 1055.0
Deduct 3205 from 3333 and we're left with 128.
Bring next digit (8) of the dividend behind the 128 and repeat the process: 1288 / 641

Moving on to step 7:
When dividing 1288 by 641, we get 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 10552.0
If we take 1282 away from 1288, we end up with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 641

Advancing to step 8:
641 can be fit into 60 0 times, resulting in a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 105520.0
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 9:
When dividing 600 by 641, we get 0 with a remainder of 600.
Put 0 as the next digit of the answer. 
Result so far: 105520.0
Deduct 0 from 600 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Step 10:
When dividing 6000 by 641, we get 9 with a remainder of 231.
The number 9 becomes the next digit in our result. 
Result so far: 105520.09
If we subtract 5769 from 6000, we get 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Advancing to step 11:
When dividing 2310 by 641, we get 3 with a remainder of 387.
The number 3 becomes the next digit in our result. 
Result so far: 105520.093
Subtract 1923 from 2310 to get 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Advancing to step 12:
3870 divided by 641 is 6 with a remainder of 24.
The next digit of our result is 6. 
Result so far: 105520.0936
Subtracting 3846 from 3870 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 13:
641 can be fit into 240 0 times, resulting in a remainder of 240.
Write down 0 as next digit of the result. 
Result so far: 105520.0936
If we take 0 away from 240, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 14:
When dividing 2400 by 641, we get 3 with a remainder of 477.
Record the quotient 3 as the next digit in the result. 
Result so far: 105520.093603
If we take 1923 away from 2400, we end up with 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

Moving on to step 15:
If we divide 4770 by 641, we get 7 and a remainder of 283.
The next digit of our result is 7. 
Result so far: 105520.0936037
Subtracting 4487 from 4770 leaves us 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.

Advancing to step 16:
641 goes into 2830 4 times with a remainder of 266.
The next digit of our result is 4. 
Result so far: 105520.09360374
If we take 2564 away from 2830, we end up with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

In conclusion, the division gives 105520.09360374 with a balance of 2.66e-07.
