We're dividing 75850483 by 421 
We want to figure out the number of times 75850483 can be divided by 421.

Step 1:
The number 421 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 421

Moving on to step 2:
75 divided by 421 is 0 with a remainder of 75.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Grab the next digit (8) from the dividend, add it to 75, then carry on: 758 / 421

Going ahead to step 3:
The number 421 fits into 758 1 times, leaving a remainder of 337.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 337 after subtracting 421 from 758.
Fetch the next digit (5) from the dividend, attach it to 337 and continue: 3375 / 421

On to step 4:
The number 421 fits into 3375 8 times, leaving a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Deduct 3368 from 3375 and we're left with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 421

On to step 5:
The number 421 fits into 70 0 times, leaving a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 180.0
Subtract 0 from 70 to get 70.
Append the next digit (4) from the dividend to 70 and continue with: 704 / 421

Advancing to step 6:
When dividing 704 by 421, we get 1 with a remainder of 283.
Record the quotient 1 as the next digit in the result. 
Result so far: 1801.0
The remainder is 283 after subtracting 421 from 704.
Bring next digit (8) of the dividend behind the 283 and repeat the process: 2838 / 421

On to step 7:
421 goes into 2838 6 times with a remainder of 312.
Use 6 as the next digit of our solution. 
Result so far: 18016.0
Subtract 2526 from 2838 to get 312.
Take the next digit (3) from the dividend and append it to 312, then repeat: 3123 / 421

Step 8:
421 goes into 3123 7 times with a remainder of 176.
Put 7 as the next digit of the answer. 
Result so far: 180167.0
Subtracting 2947 from 3123 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Going ahead to step 9:
The number 421 fits into 1760 4 times, leaving a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 180167.4
If we take 1684 away from 1760, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 10:
The number 421 fits into 760 1 times, leaving a remainder of 339.
The number 1 becomes the next digit in our result. 
Result so far: 180167.41
If we take 421 away from 760, we end up with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Going ahead to step 11:
If we divide 3390 by 421, we get 8 and a remainder of 22.
The next digit of our result is 8. 
Result so far: 180167.418
If we subtract 3368 from 3390, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 12:
When dividing 220 by 421, we get 0 with a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 180167.418
If we take 0 away from 220, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 13:
421 goes into 2200 5 times with a remainder of 95.
Put 5 as the next digit of the answer. 
Result so far: 180167.41805
Subtracting 2105 from 2200 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Let's proceed to step 14:
When dividing 950 by 421, we get 2 with a remainder of 108.
The number 2 becomes the next digit in our result. 
Result so far: 180167.418052
Subtracting 842 from 950 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Let's proceed to step 15:
421 can be fit into 1080 2 times, resulting in a remainder of 238.
Write down 2 as next digit of the result. 
Result so far: 180167.4180522
Subtract 842 from 1080 to get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

The final outcome is 180167.4180522, with a leftover of 2.38e-06.
