We look at the division of 45170571 by 419 
We're looking to find how many times 419 goes into 45170571.

On to step 1:
419 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 419

On to step 2:
The number 419 fits into 45 0 times, leaving a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Include the next digit (1) from the dividend after 45, then repeat: 451 / 419

Step 3:
451 divided by 419 is 1 with a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 32 after subtracting 419 from 451.
Bring next digit (7) of the dividend behind the 32 and repeat the process: 327 / 419

Moving on to step 4:
When dividing 327 by 419, we get 0 with a remainder of 327.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 327 leaves us with 327.
Bring next digit (0) of the dividend behind the 327 and repeat the process: 3270 / 419

Advancing to step 5:
419 goes into 3270 7 times with a remainder of 337.
Record the quotient 7 as the next digit in the result. 
Result so far: 107.0
Deduct 2933 from 3270 and we're left with 337.
Append the next digit (5) from the dividend to 337 and continue with: 3375 / 419

On to step 6:
419 goes into 3375 8 times with a remainder of 23.
Write down 8 as next digit of the result. 
Result so far: 1078.0
Subtract 3352 from 3375 to get 23.
Take the next digit (7) from the dividend and append it to 23, then repeat: 237 / 419

Step 7:
237 divided by 419 is 0 with a remainder of 237.
Record the quotient 0 as the next digit in the result. 
Result so far: 10780.0
If we subtract 0 from 237, we get 237.
Bring next digit (1) of the dividend behind the 237 and repeat the process: 2371 / 419

Going ahead to step 8:
The number 419 fits into 2371 5 times, leaving a remainder of 276.
Use 5 as the next digit of our solution. 
Result so far: 107805.0
Subtract 2095 from 2371 to get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Going ahead to step 9:
419 goes into 2760 6 times with a remainder of 246.
Write down 6 as next digit of the result. 
Result so far: 107805.6
Subtracting 2514 from 2760 leaves us with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Advancing to step 10:
If we divide 2460 by 419, we get 5 and a remainder of 365.
The next digit of our result is 5. 
Result so far: 107805.65
Subtracting 2095 from 2460 leaves us with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Let's proceed to step 11:
When dividing 3650 by 419, we get 8 with a remainder of 298.
Use 8 as the next digit of our solution. 
Result so far: 107805.658
If we subtract 3352 from 3650, we get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Advancing to step 12:
The number 419 fits into 2980 7 times, leaving a remainder of 47.
Put 7 as the next digit of the answer. 
Result so far: 107805.6587
The remainder is 47 after subtracting 2933 from 2980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 13:
The number 419 fits into 470 1 times, leaving a remainder of 51.
Use 1 as the next digit of our solution. 
Result so far: 107805.65871
Subtracting 419 from 470 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 14:
510 divided by 419 is 1 with a remainder of 91.
Use 1 as the next digit of our solution. 
Result so far: 107805.658711
Deduct 419 from 510 and we're left with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

The quotient of the division is 107805.658711, and the remainder is 9.1e-06.
