We look at the division of 74204978 by 641 
Let's see how many times 641 fits into 74204978.

Going ahead to step 1:
The number 641 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 641

Advancing to step 2:
74 divided by 641 is 0 with a remainder of 74.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Bring next digit (2) of the dividend behind the 74 and repeat the process: 742 / 641

Going ahead to step 3:
742 divided by 641 is 1 with a remainder of 101.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 641 away from 742, we end up with 101.
Append the next digit (0) from the dividend to 101 and continue with: 1010 / 641

Step 4:
641 goes into 1010 1 times with a remainder of 369.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 641 from 1010, we get 369.
Include the next digit (4) from the dividend after 369, then repeat: 3694 / 641

Advancing to step 5:
When dividing 3694 by 641, we get 5 with a remainder of 489.
Record the quotient 5 as the next digit in the result. 
Result so far: 115.0
Deduct 3205 from 3694 and we're left with 489.
Fetch the next digit (9) from the dividend, attach it to 489 and continue: 4899 / 641

On to step 6:
If we divide 4899 by 641, we get 7 and a remainder of 412.
Record the quotient 7 as the next digit in the result. 
Result so far: 1157.0
Subtract 4487 from 4899 to get 412.
Bring next digit (7) of the dividend behind the 412 and repeat the process: 4127 / 641

Let's proceed to step 7:
4127 divided by 641 is 6 with a remainder of 281.
The number 6 becomes the next digit in our result. 
Result so far: 11576.0
The remainder is 281 after subtracting 3846 from 4127.
Take the next digit (8) from the dividend and append it to 281, then repeat: 2818 / 641

Let's proceed to step 8:
The number 641 fits into 2818 4 times, leaving a remainder of 254.
Record the quotient 4 as the next digit in the result. 
Result so far: 115764.0
If we subtract 2564 from 2818, we get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

On to step 9:
641 goes into 2540 3 times with a remainder of 617.
Use 3 as the next digit of our solution. 
Result so far: 115764.3
If we subtract 1923 from 2540, we get 617.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6170, and continue the process.

Advancing to step 10:
641 can be fit into 6170 9 times, resulting in a remainder of 401.
The next digit of our result is 9. 
Result so far: 115764.39
If we take 5769 away from 6170, we end up with 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Step 11:
When dividing 4010 by 641, we get 6 with a remainder of 164.
Use 6 as the next digit of our solution. 
Result so far: 115764.396
Subtracting 3846 from 4010 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Advancing to step 12:
The number 641 fits into 1640 2 times, leaving a remainder of 358.
Use 2 as the next digit of our solution. 
Result so far: 115764.3962
If we subtract 1282 from 1640, we get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Moving on to step 13:
3580 divided by 641 is 5 with a remainder of 375.
The next digit of our result is 5. 
Result so far: 115764.39625
The remainder is 375 after subtracting 3205 from 3580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Step 14:
If we divide 3750 by 641, we get 5 and a remainder of 545.
The number 5 becomes the next digit in our result. 
Result so far: 115764.396255
The remainder is 545 after subtracting 3205 from 3750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

The final result is 115764.396255 with a remainder of 5.45e-05.
