We look at the division of 79171541 by 157 
We want to figure out the number of times 79171541 can be divided by 157.

On to step 1:
If we divide 7 by 157, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 157

Step 2:
157 goes into 79 0 times with a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Append the next digit (1) from the dividend to 79 and continue with: 791 / 157

Step 3:
The number 157 fits into 791 5 times, leaving a remainder of 6.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 785 from 791, we get 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 157

Step 4:
If we divide 67 by 157, we get 0 and a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 50.0
Subtracting 0 from 67 leaves us with 67.
Grab the next digit (1) from the dividend, add it to 67, then carry on: 671 / 157

Moving on to step 5:
157 can be fit into 671 4 times, resulting in a remainder of 43.
The number 4 becomes the next digit in our result. 
Result so far: 504.0
Subtract 628 from 671 to get 43.
Include the next digit (5) from the dividend after 43, then repeat: 435 / 157

Moving on to step 6:
157 goes into 435 2 times with a remainder of 121.
Put 2 as the next digit of the answer. 
Result so far: 5042.0
If we take 314 away from 435, we end up with 121.
Append the next digit (4) from the dividend to 121 and continue with: 1214 / 157

On to step 7:
157 goes into 1214 7 times with a remainder of 115.
The next digit of our result is 7. 
Result so far: 50427.0
If we take 1099 away from 1214, we end up with 115.
Bring next digit (1) of the dividend behind the 115 and repeat the process: 1151 / 157

Step 8:
157 goes into 1151 7 times with a remainder of 52.
The next digit of our result is 7. 
Result so far: 504277.0
The remainder is 52 after subtracting 1099 from 1151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 9:
520 divided by 157 is 3 with a remainder of 49.
The next digit of our result is 3. 
Result so far: 504277.3
The remainder is 49 after subtracting 471 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 10:
If we divide 490 by 157, we get 3 and a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 504277.33
Subtract 471 from 490 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The quotient of the division is 504277.33, and the remainder is 0.019.
