We divide 80018944 by 641
We want to divide 80018944 by 641.

Step 1:
If we divide 8 by 641, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 641

On to step 2:
If we divide 80 by 641, we get 0 and a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Take the next digit (0) from the dividend and append it to 80, then repeat: 800 / 641

Advancing to step 3:
641 goes into 800 1 times with a remainder of 159.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 641 from 800, we get 159.
Take the next digit (1) from the dividend and append it to 159, then repeat: 1591 / 641

Let's proceed to step 4:
The number 641 fits into 1591 2 times, leaving a remainder of 309.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 309 after subtracting 1282 from 1591.
Grab the next digit (8) from the dividend, add it to 309, then carry on: 3098 / 641

Let's proceed to step 5:
When dividing 3098 by 641, we get 4 with a remainder of 534.
The next digit of our result is 4. 
Result so far: 124.0
Subtracting 2564 from 3098 leaves us with 534.
Fetch the next digit (9) from the dividend, attach it to 534 and continue: 5349 / 641

Going ahead to step 6:
When dividing 5349 by 641, we get 8 with a remainder of 221.
Write down 8 as next digit of the result. 
Result so far: 1248.0
If we subtract 5128 from 5349, we get 221.
Take the next digit (4) from the dividend and append it to 221, then repeat: 2214 / 641

Step 7:
2214 divided by 641 is 3 with a remainder of 291.
The number 3 becomes the next digit in our result. 
Result so far: 12483.0
If we take 1923 away from 2214, we end up with 291.
Bring next digit (4) of the dividend behind the 291 and repeat the process: 2914 / 641

Let's proceed to step 8:
If we divide 2914 by 641, we get 4 and a remainder of 350.
The number 4 becomes the next digit in our result. 
Result so far: 124834.0
The remainder is 350 after subtracting 2564 from 2914.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 9:
641 can be fit into 3500 5 times, resulting in a remainder of 295.
Put 5 as the next digit of the answer. 
Result so far: 124834.5
Subtract 3205 from 3500 to get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Advancing to step 10:
641 goes into 2950 4 times with a remainder of 386.
Record the quotient 4 as the next digit in the result. 
Result so far: 124834.54
The remainder is 386 after subtracting 2564 from 2950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Let's proceed to step 11:
When dividing 3860 by 641, we get 6 with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 124834.546
The remainder is 14 after subtracting 3846 from 3860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 12:
641 goes into 140 0 times with a remainder of 140.
The number 0 becomes the next digit in our result. 
Result so far: 124834.546
Deduct 0 from 140 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 13:
641 can be fit into 1400 2 times, resulting in a remainder of 118.
Use 2 as the next digit of our solution. 
Result so far: 124834.54602
If we subtract 1282 from 1400, we get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Advancing to step 14:
When dividing 1180 by 641, we get 1 with a remainder of 539.
The number 1 becomes the next digit in our result. 
Result so far: 124834.546021
Subtract 641 from 1180 to get 539.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5390, and continue the process.

Let's proceed to step 15:
5390 divided by 641 is 8 with a remainder of 262.
The number 8 becomes the next digit in our result. 
Result so far: 124834.5460218
Subtracting 5128 from 5390 leaves us with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

On to step 16:
If we divide 2620 by 641, we get 4 and a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 124834.54602184
Deduct 2564 from 2620 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

After the division, we end up with 124834.54602184 and a remainder of 5.6e-08.
