80984995 ÷ 641 
Let's see how many times 641 fits into 80984995.

Step 1:
If we divide 8 by 641, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 641

On to step 2:
80 divided by 641 is 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Fetch the next digit (9) from the dividend, attach it to 80 and continue: 809 / 641

Let's proceed to step 3:
If we divide 809 by 641, we get 1 and a remainder of 168.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 641 from 809 to get 168.
Fetch the next digit (8) from the dividend, attach it to 168 and continue: 1688 / 641

Moving on to step 4:
If we divide 1688 by 641, we get 2 and a remainder of 406.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 1282 from 1688 and we're left with 406.
Append the next digit (4) from the dividend to 406 and continue with: 4064 / 641

Going ahead to step 5:
The number 641 fits into 4064 6 times, leaving a remainder of 218.
Record the quotient 6 as the next digit in the result. 
Result so far: 126.0
Deduct 3846 from 4064 and we're left with 218.
Take the next digit (9) from the dividend and append it to 218, then repeat: 2189 / 641

Advancing to step 6:
When dividing 2189 by 641, we get 3 with a remainder of 266.
Use 3 as the next digit of our solution. 
Result so far: 1263.0
Subtracting 1923 from 2189 leaves us with 266.
Include the next digit (9) from the dividend after 266, then repeat: 2669 / 641

On to step 7:
If we divide 2669 by 641, we get 4 and a remainder of 105.
Use 4 as the next digit of our solution. 
Result so far: 12634.0
The remainder is 105 after subtracting 2564 from 2669.
Grab the next digit (5) from the dividend, add it to 105, then carry on: 1055 / 641

Going ahead to step 8:
The number 641 fits into 1055 1 times, leaving a remainder of 414.
The number 1 becomes the next digit in our result. 
Result so far: 126341.0
Deduct 641 from 1055 and we're left with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Going ahead to step 9:
The number 641 fits into 4140 6 times, leaving a remainder of 294.
Use 6 as the next digit of our solution. 
Result so far: 126341.6
Deduct 3846 from 4140 and we're left with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Moving on to step 10:
2940 divided by 641 is 4 with a remainder of 376.
Write down 4 as next digit of the result. 
Result so far: 126341.64
Deduct 2564 from 2940 and we're left with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Step 11:
641 goes into 3760 5 times with a remainder of 555.
The number 5 becomes the next digit in our result. 
Result so far: 126341.645
If we subtract 3205 from 3760, we get 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Advancing to step 12:
5550 divided by 641 is 8 with a remainder of 422.
Put 8 as the next digit of the answer. 
Result so far: 126341.6458
If we subtract 5128 from 5550, we get 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Let's proceed to step 13:
641 can be fit into 4220 6 times, resulting in a remainder of 374.
Put 6 as the next digit of the answer. 
Result so far: 126341.64586
If we subtract 3846 from 4220, we get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Going ahead to step 14:
3740 divided by 641 is 5 with a remainder of 535.
Write down 5 as next digit of the result. 
Result so far: 126341.645865
Subtracting 3205 from 3740 leaves us with 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Advancing to step 15:
When dividing 5350 by 641, we get 8 with a remainder of 222.
Use 8 as the next digit of our solution. 
Result so far: 126341.6458658
Subtract 5128 from 5350 to get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Step 16:
641 can be fit into 2220 3 times, resulting in a remainder of 297.
Use 3 as the next digit of our solution. 
Result so far: 126341.64586583
Subtracting 1923 from 2220 leaves us with 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Our division results in 126341.64586583 with a remaining 2.97e-07.
