77842030 divided by 641 
We want to figure out the number of times 77842030 can be divided by 641.

Going ahead to step 1:
If we divide 7 by 641, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 641

Moving on to step 2:
The number 641 fits into 77 0 times, leaving a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Append the next digit (8) from the dividend to 77 and continue with: 778 / 641

Going ahead to step 3:
641 can be fit into 778 1 times, resulting in a remainder of 137.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 641 away from 778, we end up with 137.
Grab the next digit (4) from the dividend, add it to 137, then carry on: 1374 / 641

Step 4:
641 can be fit into 1374 2 times, resulting in a remainder of 92.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 1282 from 1374 and we're left with 92.
Include the next digit (2) from the dividend after 92, then repeat: 922 / 641

Moving on to step 5:
922 divided by 641 is 1 with a remainder of 281.
Record the quotient 1 as the next digit in the result. 
Result so far: 121.0
Deduct 641 from 922 and we're left with 281.
Take the next digit (0) from the dividend and append it to 281, then repeat: 2810 / 641

Moving on to step 6:
The number 641 fits into 2810 4 times, leaving a remainder of 246.
The number 4 becomes the next digit in our result. 
Result so far: 1214.0
The remainder is 246 after subtracting 2564 from 2810.
Append the next digit (3) from the dividend to 246 and continue with: 2463 / 641

Step 7:
The number 641 fits into 2463 3 times, leaving a remainder of 540.
The next digit of our result is 3. 
Result so far: 12143.0
The remainder is 540 after subtracting 1923 from 2463.
Grab the next digit (0) from the dividend, add it to 540, then carry on: 5400 / 641

Going ahead to step 8:
641 can be fit into 5400 8 times, resulting in a remainder of 272.
Put 8 as the next digit of the answer. 
Result so far: 121438.0
The remainder is 272 after subtracting 5128 from 5400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

On to step 9:
When dividing 2720 by 641, we get 4 with a remainder of 156.
Write down 4 as next digit of the result. 
Result so far: 121438.4
If we subtract 2564 from 2720, we get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Let's proceed to step 10:
641 can be fit into 1560 2 times, resulting in a remainder of 278.
Put 2 as the next digit of the answer. 
Result so far: 121438.42
If we subtract 1282 from 1560, we get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Let's proceed to step 11:
641 goes into 2780 4 times with a remainder of 216.
The number 4 becomes the next digit in our result. 
Result so far: 121438.424
If we take 2564 away from 2780, we end up with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 12:
If we divide 2160 by 641, we get 3 and a remainder of 237.
The next digit of our result is 3. 
Result so far: 121438.4243
The remainder is 237 after subtracting 1923 from 2160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Going ahead to step 13:
641 can be fit into 2370 3 times, resulting in a remainder of 447.
The number 3 becomes the next digit in our result. 
Result so far: 121438.42433
If we subtract 1923 from 2370, we get 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

The quotient of the division is 121438.42433, and the remainder is 0.000447.
