We look at the division of 80741974 by 631 
We want to divide 80741974 by 631.

Step 1:
If we divide 8 by 631, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 631

Step 2:
631 can be fit into 80 0 times, resulting in a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Fetch the next digit (7) from the dividend, attach it to 80 and continue: 807 / 631

Step 3:
The number 631 fits into 807 1 times, leaving a remainder of 176.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 631 from 807, we get 176.
Grab the next digit (4) from the dividend, add it to 176, then carry on: 1764 / 631

Moving on to step 4:
1764 divided by 631 is 2 with a remainder of 502.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 1262 from 1764 and we're left with 502.
Include the next digit (1) from the dividend after 502, then repeat: 5021 / 631

Going ahead to step 5:
If we divide 5021 by 631, we get 7 and a remainder of 604.
Put 7 as the next digit of the answer. 
Result so far: 127.0
Deduct 4417 from 5021 and we're left with 604.
Grab the next digit (9) from the dividend, add it to 604, then carry on: 6049 / 631

Let's proceed to step 6:
If we divide 6049 by 631, we get 9 and a remainder of 370.
Put 9 as the next digit of the answer. 
Result so far: 1279.0
If we subtract 5679 from 6049, we get 370.
Grab the next digit (7) from the dividend, add it to 370, then carry on: 3707 / 631

Moving on to step 7:
3707 divided by 631 is 5 with a remainder of 552.
The number 5 becomes the next digit in our result. 
Result so far: 12795.0
Subtracting 3155 from 3707 leaves us with 552.
Include the next digit (4) from the dividend after 552, then repeat: 5524 / 631

Advancing to step 8:
When dividing 5524 by 631, we get 8 with a remainder of 476.
The number 8 becomes the next digit in our result. 
Result so far: 127958.0
If we take 5048 away from 5524, we end up with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Let's proceed to step 9:
631 goes into 4760 7 times with a remainder of 343.
The number 7 becomes the next digit in our result. 
Result so far: 127958.7
If we take 4417 away from 4760, we end up with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Let's proceed to step 10:
631 can be fit into 3430 5 times, resulting in a remainder of 275.
Use 5 as the next digit of our solution. 
Result so far: 127958.75
If we subtract 3155 from 3430, we get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Moving on to step 11:
If we divide 2750 by 631, we get 4 and a remainder of 226.
Put 4 as the next digit of the answer. 
Result so far: 127958.754
Deduct 2524 from 2750 and we're left with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Moving on to step 12:
When dividing 2260 by 631, we get 3 with a remainder of 367.
Use 3 as the next digit of our solution. 
Result so far: 127958.7543
Subtracting 1893 from 2260 leaves us with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Step 13:
631 goes into 3670 5 times with a remainder of 515.
Record the quotient 5 as the next digit in the result. 
Result so far: 127958.75435
If we take 3155 away from 3670, we end up with 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Step 14:
631 can be fit into 5150 8 times, resulting in a remainder of 102.
Use 8 as the next digit of our solution. 
Result so far: 127958.754358
Subtracting 5048 from 5150 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Moving on to step 15:
If we divide 1020 by 631, we get 1 and a remainder of 389.
The number 1 becomes the next digit in our result. 
Result so far: 127958.7543581
If we subtract 631 from 1020, we get 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Advancing to step 16:
The number 631 fits into 3890 6 times, leaving a remainder of 104.
The next digit of our result is 6. 
Result so far: 127958.75435816
If we subtract 3786 from 3890, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

The final result is 127958.75435816 with a remainder of 1.04e-07.
