Let's divide 74454963 by 17
We want to figure out the number of times 74454963 can be divided by 17.

On to step 1:
When dividing 7 by 17, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 17

Going ahead to step 2:
17 goes into 74 4 times with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 68 from 74, we get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 17

Advancing to step 3:
The number 17 fits into 64 3 times, leaving a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
The remainder is 13 after subtracting 51 from 64.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 17

On to step 4:
If we divide 135 by 17, we get 7 and a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 437.0
If we take 119 away from 135, we end up with 16.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 17

Moving on to step 5:
17 goes into 164 9 times with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 4379.0
Deduct 153 from 164 and we're left with 11.
Include the next digit (9) from the dividend after 11, then repeat: 119 / 17

Step 6:
The number 17 fits into 119 7 times, leaving a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 43797.0
The remainder is 0 after subtracting 119 from 119.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 17

Moving on to step 7:
6 divided by 17 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 437970.0
If we take 0 away from 6, we end up with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 17

Going ahead to step 8:
If we divide 63 by 17, we get 3 and a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 4379703.0
Deduct 51 from 63 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
The number 17 fits into 120 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 4379703.7
If we subtract 119 from 120, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 10:
17 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 4379703.7
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
100 divided by 17 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 4379703.705
The remainder is 15 after subtracting 85 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 12:
17 goes into 150 8 times with a remainder of 14.
The next digit of our result is 8. 
Result so far: 4379703.7058
If we take 136 away from 150, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 13:
If we divide 140 by 17, we get 8 and a remainder of 4.
The next digit of our result is 8. 
Result so far: 4379703.70588
The remainder is 4 after subtracting 136 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 4379703.70588, with a leftover of 4e-06.
