90240670 ÷ 475 
We're looking to find how many times 475 goes into 90240670.

Going ahead to step 1:
The number 475 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 475

Moving on to step 2:
When dividing 90 by 475, we get 0 with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Grab the next digit (2) from the dividend, add it to 90, then carry on: 902 / 475

On to step 3:
The number 475 fits into 902 1 times, leaving a remainder of 427.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 475 from 902 leaves us with 427.
Grab the next digit (4) from the dividend, add it to 427, then carry on: 4274 / 475

Going ahead to step 4:
The number 475 fits into 4274 8 times, leaving a remainder of 474.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Subtracting 3800 from 4274 leaves us with 474.
Grab the next digit (0) from the dividend, add it to 474, then carry on: 4740 / 475

Let's proceed to step 5:
The number 475 fits into 4740 9 times, leaving a remainder of 465.
The number 9 becomes the next digit in our result. 
Result so far: 189.0
If we take 4275 away from 4740, we end up with 465.
Grab the next digit (6) from the dividend, add it to 465, then carry on: 4656 / 475

Let's proceed to step 6:
The number 475 fits into 4656 9 times, leaving a remainder of 381.
Put 9 as the next digit of the answer. 
Result so far: 1899.0
Deduct 4275 from 4656 and we're left with 381.
Take the next digit (7) from the dividend and append it to 381, then repeat: 3817 / 475

Advancing to step 7:
475 goes into 3817 8 times with a remainder of 17.
Use 8 as the next digit of our solution. 
Result so far: 18998.0
Subtracting 3800 from 3817 leaves us with 17.
Take the next digit (0) from the dividend and append it to 17, then repeat: 170 / 475

Going ahead to step 8:
475 goes into 170 0 times with a remainder of 170.
The next digit of our result is 0. 
Result so far: 189980.0
Deduct 0 from 170 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 9:
475 can be fit into 1700 3 times, resulting in a remainder of 275.
Use 3 as the next digit of our solution. 
Result so far: 189980.3
The remainder is 275 after subtracting 1425 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Going ahead to step 10:
475 can be fit into 2750 5 times, resulting in a remainder of 375.
The next digit of our result is 5. 
Result so far: 189980.35
The remainder is 375 after subtracting 2375 from 2750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Step 11:
If we divide 3750 by 475, we get 7 and a remainder of 425.
Use 7 as the next digit of our solution. 
Result so far: 189980.357
If we subtract 3325 from 3750, we get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

On to step 12:
475 can be fit into 4250 8 times, resulting in a remainder of 450.
Use 8 as the next digit of our solution. 
Result so far: 189980.3578
Subtracting 3800 from 4250 leaves us with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 13:
475 can be fit into 4500 9 times, resulting in a remainder of 225.
Put 9 as the next digit of the answer. 
Result so far: 189980.35789
Subtract 4275 from 4500 to get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Step 14:
475 goes into 2250 4 times with a remainder of 350.
Use 4 as the next digit of our solution. 
Result so far: 189980.357894
Deduct 1900 from 2250 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 15:
475 goes into 3500 7 times with a remainder of 175.
Record the quotient 7 as the next digit in the result. 
Result so far: 189980.3578947
Subtracting 3325 from 3500 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Let's proceed to step 16:
475 can be fit into 1750 3 times, resulting in a remainder of 325.
The next digit of our result is 3. 
Result so far: 189980.35789473
If we take 1425 away from 1750, we end up with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

After the division, we end up with 189980.35789473 and a remainder of 3.25e-07.
