75213579 ÷ 428 
We want to figure out the number of times 75213579 can be divided by 428.

Advancing to step 1:
When dividing 7 by 428, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 428

Advancing to step 2:
75 divided by 428 is 0 with a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Append the next digit (2) from the dividend to 75 and continue with: 752 / 428

Going ahead to step 3:
428 goes into 752 1 times with a remainder of 324.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 428 away from 752, we end up with 324.
Grab the next digit (1) from the dividend, add it to 324, then carry on: 3241 / 428

Moving on to step 4:
428 goes into 3241 7 times with a remainder of 245.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we take 2996 away from 3241, we end up with 245.
Include the next digit (3) from the dividend after 245, then repeat: 2453 / 428

Going ahead to step 5:
When dividing 2453 by 428, we get 5 with a remainder of 313.
Write down 5 as next digit of the result. 
Result so far: 175.0
The remainder is 313 after subtracting 2140 from 2453.
Append the next digit (5) from the dividend to 313 and continue with: 3135 / 428

Going ahead to step 6:
428 goes into 3135 7 times with a remainder of 139.
The number 7 becomes the next digit in our result. 
Result so far: 1757.0
The remainder is 139 after subtracting 2996 from 3135.
Take the next digit (7) from the dividend and append it to 139, then repeat: 1397 / 428

Advancing to step 7:
If we divide 1397 by 428, we get 3 and a remainder of 113.
Use 3 as the next digit of our solution. 
Result so far: 17573.0
If we take 1284 away from 1397, we end up with 113.
Include the next digit (9) from the dividend after 113, then repeat: 1139 / 428

Let's proceed to step 8:
428 goes into 1139 2 times with a remainder of 283.
The next digit of our result is 2. 
Result so far: 175732.0
If we take 856 away from 1139, we end up with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Moving on to step 9:
When dividing 2830 by 428, we get 6 with a remainder of 262.
Record the quotient 6 as the next digit in the result. 
Result so far: 175732.6
Subtracting 2568 from 2830 leaves us with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Advancing to step 10:
The number 428 fits into 2620 6 times, leaving a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 175732.66
Subtract 2568 from 2620 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final outcome is 175732.66, with a leftover of 0.052.
