We're dividing 90141513 by 213 
We want to divide 90141513 by 213.

Step 1:
The number 213 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 213

Moving on to step 2:
213 goes into 90 0 times with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Include the next digit (1) from the dividend after 90, then repeat: 901 / 213

Step 3:
901 divided by 213 is 4 with a remainder of 49.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 852 from 901 leaves us with 49.
Include the next digit (4) from the dividend after 49, then repeat: 494 / 213

Step 4:
When dividing 494 by 213, we get 2 with a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
If we take 426 away from 494, we end up with 68.
Append the next digit (1) from the dividend to 68 and continue with: 681 / 213

Advancing to step 5:
When dividing 681 by 213, we get 3 with a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 423.0
Deduct 639 from 681 and we're left with 42.
Take the next digit (5) from the dividend and append it to 42, then repeat: 425 / 213

On to step 6:
213 can be fit into 425 1 times, resulting in a remainder of 212.
The number 1 becomes the next digit in our result. 
Result so far: 4231.0
If we take 213 away from 425, we end up with 212.
Grab the next digit (1) from the dividend, add it to 212, then carry on: 2121 / 213

Advancing to step 7:
If we divide 2121 by 213, we get 9 and a remainder of 204.
Put 9 as the next digit of the answer. 
Result so far: 42319.0
The remainder is 204 after subtracting 1917 from 2121.
Fetch the next digit (3) from the dividend, attach it to 204 and continue: 2043 / 213

Moving on to step 8:
2043 divided by 213 is 9 with a remainder of 126.
Write down 9 as next digit of the result. 
Result so far: 423199.0
If we subtract 1917 from 2043, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Going ahead to step 9:
1260 divided by 213 is 5 with a remainder of 195.
The number 5 becomes the next digit in our result. 
Result so far: 423199.5
Subtracting 1065 from 1260 leaves us with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Let's proceed to step 10:
When dividing 1950 by 213, we get 9 with a remainder of 33.
Put 9 as the next digit of the answer. 
Result so far: 423199.59
Subtracting 1917 from 1950 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 11:
330 divided by 213 is 1 with a remainder of 117.
Use 1 as the next digit of our solution. 
Result so far: 423199.591
If we subtract 213 from 330, we get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Moving on to step 12:
If we divide 1170 by 213, we get 5 and a remainder of 105.
The next digit of our result is 5. 
Result so far: 423199.5915
The remainder is 105 after subtracting 1065 from 1170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Moving on to step 13:
1050 divided by 213 is 4 with a remainder of 198.
Write down 4 as next digit of the result. 
Result so far: 423199.59154
The remainder is 198 after subtracting 852 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Going ahead to step 14:
1980 divided by 213 is 9 with a remainder of 63.
Record the quotient 9 as the next digit in the result. 
Result so far: 423199.591549
Deduct 1917 from 1980 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 15:
213 goes into 630 2 times with a remainder of 204.
The next digit of our result is 2. 
Result so far: 423199.5915492
Subtracting 426 from 630 leaves us with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Going ahead to step 16:
213 goes into 2040 9 times with a remainder of 123.
The next digit of our result is 9. 
Result so far: 423199.59154929
The remainder is 123 after subtracting 1917 from 2040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

The final outcome is 423199.59154929, with a leftover of 1.23e-07.
