We look at the division of 90028930 by 451 
We want to divide 90028930 by 451.

On to step 1:
When dividing 9 by 451, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 451

Advancing to step 2:
If we divide 90 by 451, we get 0 and a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Take the next digit (0) from the dividend and append it to 90, then repeat: 900 / 451

Let's proceed to step 3:
If we divide 900 by 451, we get 1 and a remainder of 449.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 451 from 900, we get 449.
Take the next digit (2) from the dividend and append it to 449, then repeat: 4492 / 451

Moving on to step 4:
When dividing 4492 by 451, we get 9 with a remainder of 433.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtracting 4059 from 4492 leaves us with 433.
Take the next digit (8) from the dividend and append it to 433, then repeat: 4338 / 451

On to step 5:
4338 divided by 451 is 9 with a remainder of 279.
Record the quotient 9 as the next digit in the result. 
Result so far: 199.0
Subtract 4059 from 4338 to get 279.
Take the next digit (9) from the dividend and append it to 279, then repeat: 2799 / 451

Going ahead to step 6:
451 goes into 2799 6 times with a remainder of 93.
Put 6 as the next digit of the answer. 
Result so far: 1996.0
Subtract 2706 from 2799 to get 93.
Grab the next digit (3) from the dividend, add it to 93, then carry on: 933 / 451

Advancing to step 7:
The number 451 fits into 933 2 times, leaving a remainder of 31.
The next digit of our result is 2. 
Result so far: 19962.0
Deduct 902 from 933 and we're left with 31.
Fetch the next digit (0) from the dividend, attach it to 31 and continue: 310 / 451

Advancing to step 8:
The number 451 fits into 310 0 times, leaving a remainder of 310.
The number 0 becomes the next digit in our result. 
Result so far: 199620.0
The remainder is 310 after subtracting 0 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 9:
When dividing 3100 by 451, we get 6 with a remainder of 394.
Write down 6 as next digit of the result. 
Result so far: 199620.6
Subtract 2706 from 3100 to get 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Moving on to step 10:
When dividing 3940 by 451, we get 8 with a remainder of 332.
The number 8 becomes the next digit in our result. 
Result so far: 199620.68
If we subtract 3608 from 3940, we get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Going ahead to step 11:
If we divide 3320 by 451, we get 7 and a remainder of 163.
The number 7 becomes the next digit in our result. 
Result so far: 199620.687
If we take 3157 away from 3320, we end up with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Advancing to step 12:
When dividing 1630 by 451, we get 3 with a remainder of 277.
Write down 3 as next digit of the result. 
Result so far: 199620.6873
Subtract 1353 from 1630 to get 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

On to step 13:
451 goes into 2770 6 times with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 199620.68736
Deduct 2706 from 2770 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 14:
451 goes into 640 1 times with a remainder of 189.
The next digit of our result is 1. 
Result so far: 199620.687361
Deduct 451 from 640 and we're left with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Advancing to step 15:
The number 451 fits into 1890 4 times, leaving a remainder of 86.
The next digit of our result is 4. 
Result so far: 199620.6873614
Subtracting 1804 from 1890 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 16:
When dividing 860 by 451, we get 1 with a remainder of 409.
Write down 1 as next digit of the result. 
Result so far: 199620.68736141
If we take 451 away from 860, we end up with 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

The final result is 199620.68736141 with a remainder of 4.09e-07.
