3415170 ÷ 749 
We want to figure out the number of times 3415170 can be divided by 749.

Moving on to step 1:
When dividing 3 by 749, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 749

Step 2:
If we divide 34 by 749, we get 0 and a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 34 leaves us with 34.
Fetch the next digit (1) from the dividend, attach it to 34 and continue: 341 / 749

Let's proceed to step 3:
749 goes into 341 0 times with a remainder of 341.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 341, we get 341.
Bring next digit (5) of the dividend behind the 341 and repeat the process: 3415 / 749

Moving on to step 4:
If we divide 3415 by 749, we get 4 and a remainder of 419.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 2996 from 3415 leaves us with 419.
Include the next digit (1) from the dividend after 419, then repeat: 4191 / 749

Step 5:
749 can be fit into 4191 5 times, resulting in a remainder of 446.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Subtracting 3745 from 4191 leaves us with 446.
Bring next digit (7) of the dividend behind the 446 and repeat the process: 4467 / 749

Advancing to step 6:
4467 divided by 749 is 5 with a remainder of 722.
The number 5 becomes the next digit in our result. 
Result so far: 455.0
If we subtract 3745 from 4467, we get 722.
Bring next digit (0) of the dividend behind the 722 and repeat the process: 7220 / 749

Moving on to step 7:
749 goes into 7220 9 times with a remainder of 479.
Put 9 as the next digit of the answer. 
Result so far: 4559.0
If we take 6741 away from 7220, we end up with 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

On to step 8:
The number 749 fits into 4790 6 times, leaving a remainder of 296.
The next digit of our result is 6. 
Result so far: 4559.6
If we take 4494 away from 4790, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

On to step 9:
749 goes into 2960 3 times with a remainder of 713.
The next digit of our result is 3. 
Result so far: 4559.63
The remainder is 713 after subtracting 2247 from 2960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7130, and continue the process.

Advancing to step 10:
When dividing 7130 by 749, we get 9 with a remainder of 389.
Put 9 as the next digit of the answer. 
Result so far: 4559.639
Subtracting 6741 from 7130 leaves us with 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Let's proceed to step 11:
749 goes into 3890 5 times with a remainder of 145.
The number 5 becomes the next digit in our result. 
Result so far: 4559.6395
Subtract 3745 from 3890 to 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.

Let's proceed to step 12:
749 goes into 1450 1 times with a remainder of 701.
Write down 1 as next digit of the result. 
Result so far: 4559.63951
Subtracting 749 from 1450 leaves us with 701.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7010, and continue the process.

Going ahead to step 13:
749 can be fit into 7010 9 times, resulting in a remainder of 269.
Write down 9 as next digit of the result. 
Result so far: 4559.639519
If we subtract 6741 from 7010, we get 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

On to step 14:
When dividing 2690 by 749, we get 3 with a remainder of 443.
The next digit of our result is 3. 
Result so far: 4559.6395193
If we subtract 2247 from 2690, we get 443.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

Moving on to step 15:
The number 749 fits into 4430 5 times, leaving a remainder of 685.
Use 5 as the next digit of our solution. 
Result so far: 4559.63951935
Subtracting 3745 from 4430 leaves us with 685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

After the division, we end up with 4559.63951935 and a remainder of 6.85e-07.
