Let's divide 80220385 by 641
Our goal is to divide 80220385 by 641.

Going ahead to step 1:
641 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 641

Going ahead to step 2:
If we divide 80 by 641, we get 0 and a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Grab the next digit (2) from the dividend, add it to 80, then carry on: 802 / 641

Advancing to step 3:
641 goes into 802 1 times with a remainder of 161.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 641 from 802 to get 161.
Append the next digit (2) from the dividend to 161 and continue with: 1612 / 641

On to step 4:
If we divide 1612 by 641, we get 2 and a remainder of 330.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 1282 from 1612 to get 330.
Include the next digit (0) from the dividend after 330, then repeat: 3300 / 641

Going ahead to step 5:
641 goes into 3300 5 times with a remainder of 95.
The next digit of our result is 5. 
Result so far: 125.0
Subtracting 3205 from 3300 leaves us with 95.
Include the next digit (3) from the dividend after 95, then repeat: 953 / 641

On to step 6:
If we divide 953 by 641, we get 1 and a remainder of 312.
Use 1 as the next digit of our solution. 
Result so far: 1251.0
If we take 641 away from 953, we end up with 312.
Grab the next digit (8) from the dividend, add it to 312, then carry on: 3128 / 641

Advancing to step 7:
If we divide 3128 by 641, we get 4 and a remainder of 564.
Write down 4 as next digit of the result. 
Result so far: 12514.0
If we subtract 2564 from 3128, we get 564.
Take the next digit (5) from the dividend and append it to 564, then repeat: 5645 / 641

Advancing to step 8:
The number 641 fits into 5645 8 times, leaving a remainder of 517.
Write down 8 as next digit of the result. 
Result so far: 125148.0
If we take 5128 away from 5645, we end up with 517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

Going ahead to step 9:
If we divide 5170 by 641, we get 8 and a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 125148.8
If we take 5128 away from 5170, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 10:
When dividing 420 by 641, we get 0 with a remainder of 420.
Write down 0 as next digit of the result. 
Result so far: 125148.8
Subtract 0 from 420 to get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Going ahead to step 11:
641 goes into 4200 6 times with a remainder of 354.
The next digit of our result is 6. 
Result so far: 125148.806
The remainder is 354 after subtracting 3846 from 4200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Let's proceed to step 12:
The number 641 fits into 3540 5 times, leaving a remainder of 335.
Write down 5 as next digit of the result. 
Result so far: 125148.8065
Subtract 3205 from 3540 to get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Let's proceed to step 13:
If we divide 3350 by 641, we get 5 and a remainder of 145.
Use 5 as the next digit of our solution. 
Result so far: 125148.80655
If we subtract 3205 from 3350, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

The final result is 125148.80655 with a remainder of 0.000145.
