Let's divide 77281288 by 641
We want to divide 77281288 by 641.

Advancing to step 1:
If we divide 7 by 641, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 641

Moving on to step 2:
641 goes into 77 0 times with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Bring next digit (2) of the dividend behind the 77 and repeat the process: 772 / 641

Step 3:
772 divided by 641 is 1 with a remainder of 131.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 131 after subtracting 641 from 772.
Fetch the next digit (8) from the dividend, attach it to 131 and continue: 1318 / 641

Step 4:
The number 641 fits into 1318 2 times, leaving a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 1282 from 1318 and we're left with 36.
Grab the next digit (1) from the dividend, add it to 36, then carry on: 361 / 641

On to step 5:
361 divided by 641 is 0 with a remainder of 361.
The number 0 becomes the next digit in our result. 
Result so far: 120.0
Deduct 0 from 361 and we're left with 361.
Bring next digit (2) of the dividend behind the 361 and repeat the process: 3612 / 641

Advancing to step 6:
The number 641 fits into 3612 5 times, leaving a remainder of 407.
The number 5 becomes the next digit in our result. 
Result so far: 1205.0
Subtract 3205 from 3612 to get 407.
Grab the next digit (8) from the dividend, add it to 407, then carry on: 4078 / 641

Going ahead to step 7:
641 can be fit into 4078 6 times, resulting in a remainder of 232.
Write down 6 as next digit of the result. 
Result so far: 12056.0
Subtract 3846 from 4078 to get 232.
Append the next digit (8) from the dividend to 232 and continue with: 2328 / 641

Advancing to step 8:
When dividing 2328 by 641, we get 3 with a remainder of 405.
The next digit of our result is 3. 
Result so far: 120563.0
Subtract 1923 from 2328 to get 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

On to step 9:
When dividing 4050 by 641, we get 6 with a remainder of 204.
Write down 6 as next digit of the result. 
Result so far: 120563.6
Subtracting 3846 from 4050 leaves us with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Step 10:
If we divide 2040 by 641, we get 3 and a remainder of 117.
The number 3 becomes the next digit in our result. 
Result so far: 120563.63
Subtracting 1923 from 2040 leaves us with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Moving on to step 11:
641 can be fit into 1170 1 times, resulting in a remainder of 529.
Use 1 as the next digit of our solution. 
Result so far: 120563.631
Subtracting 641 from 1170 leaves us with 529.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

Moving on to step 12:
The number 641 fits into 5290 8 times, leaving a remainder of 162.
Put 8 as the next digit of the answer. 
Result so far: 120563.6318
If we subtract 5128 from 5290, we get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

On to step 13:
1620 divided by 641 is 2 with a remainder of 338.
Write down 2 as next digit of the result. 
Result so far: 120563.63182
If we subtract 1282 from 1620, we get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

On to step 14:
641 can be fit into 3380 5 times, resulting in a remainder of 175.
Record the quotient 5 as the next digit in the result. 
Result so far: 120563.631825
Subtracting 3205 from 3380 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Step 15:
When dividing 1750 by 641, we get 2 with a remainder of 468.
Use 2 as the next digit of our solution. 
Result so far: 120563.6318252
Deduct 1282 from 1750 and we're left with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Let's proceed to step 16:
If we divide 4680 by 641, we get 7 and a remainder of 193.
Record the quotient 7 as the next digit in the result. 
Result so far: 120563.63182527
Subtract 4487 from 4680 to get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

The final outcome is 120563.63182527, with a leftover of 1.93e-07.
