We look at the division of 17457069 by 428 
We want to figure out the number of times 17457069 can be divided by 428.

Let's proceed to step 1:
428 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 428

Moving on to step 2:
428 can be fit into 17 0 times, resulting in a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Grab the next digit (4) from the dividend, add it to 17, then carry on: 174 / 428

Step 3:
The number 428 fits into 174 0 times, leaving a remainder of 174.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 174, we get 174.
Include the next digit (5) from the dividend after 174, then repeat: 1745 / 428

Step 4:
When dividing 1745 by 428, we get 4 with a remainder of 33.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 1712 from 1745, we get 33.
Fetch the next digit (7) from the dividend, attach it to 33 and continue: 337 / 428

On to step 5:
When dividing 337 by 428, we get 0 with a remainder of 337.
Put 0 as the next digit of the answer. 
Result so far: 40.0
If we take 0 away from 337, we end up with 337.
Grab the next digit (0) from the dividend, add it to 337, then carry on: 3370 / 428

Step 6:
428 goes into 3370 7 times with a remainder of 374.
Record the quotient 7 as the next digit in the result. 
Result so far: 407.0
If we take 2996 away from 3370, we end up with 374.
Append the next digit (6) from the dividend to 374 and continue with: 3746 / 428

Let's proceed to step 7:
The number 428 fits into 3746 8 times, leaving a remainder of 322.
Use 8 as the next digit of our solution. 
Result so far: 4078.0
If we take 3424 away from 3746, we end up with 322.
Append the next digit (9) from the dividend to 322 and continue with: 3229 / 428

Let's proceed to step 8:
428 can be fit into 3229 7 times, resulting in a remainder of 233.
Put 7 as the next digit of the answer. 
Result so far: 40787.0
If we subtract 2996 from 3229, we get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Let's proceed to step 9:
428 goes into 2330 5 times with a remainder of 190.
The number 5 becomes the next digit in our result. 
Result so far: 40787.5
If we subtract 2140 from 2330, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 10:
428 can be fit into 1900 4 times, resulting in a remainder of 188.
Record the quotient 4 as the next digit in the result. 
Result so far: 40787.54
Subtracting 1712 from 1900 leaves us with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Let's proceed to step 11:
1880 divided by 428 is 4 with a remainder of 168.
The next digit of our result is 4. 
Result so far: 40787.544
Subtract 1712 from 1880 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

The final outcome is 40787.544, with a leftover of 0.0168.
