We look at the division of 63541571 by 451 
Our goal is to divide 63541571 by 451.

On to step 1:
The number 451 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 451

On to step 2:
63 divided by 451 is 0 with a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Grab the next digit (5) from the dividend, add it to 63, then carry on: 635 / 451

Moving on to step 3:
When dividing 635 by 451, we get 1 with a remainder of 184.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 451 from 635 and we're left with 184.
Bring next digit (4) of the dividend behind the 184 and repeat the process: 1844 / 451

Step 4:
1844 divided by 451 is 4 with a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Deduct 1804 from 1844 and we're left with 40.
Append the next digit (1) from the dividend to 40 and continue with: 401 / 451

Moving on to step 5:
When dividing 401 by 451, we get 0 with a remainder of 401.
Record the quotient 0 as the next digit in the result. 
Result so far: 140.0
Deduct 0 from 401 and we're left with 401.
Append the next digit (5) from the dividend to 401 and continue with: 4015 / 451

Advancing to step 6:
451 can be fit into 4015 8 times, resulting in a remainder of 407.
Write down 8 as next digit of the result. 
Result so far: 1408.0
Subtracting 3608 from 4015 leaves us with 407.
Append the next digit (7) from the dividend to 407 and continue with: 4077 / 451

Going ahead to step 7:
451 goes into 4077 9 times with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 14089.0
Subtracting 4059 from 4077 leaves us with 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 451

Let's proceed to step 8:
The number 451 fits into 181 0 times, leaving a remainder of 181.
The number 0 becomes the next digit in our result. 
Result so far: 140890.0
Subtract 0 from 181 to get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Advancing to step 9:
1810 divided by 451 is 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 140890.4
The remainder is 6 after subtracting 1804 from 1810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
451 goes into 60 0 times with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 140890.4
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
If we divide 600 by 451, we get 1 and a remainder of 149.
The number 1 becomes the next digit in our result. 
Result so far: 140890.401
The remainder is 149 after subtracting 451 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Advancing to step 12:
When dividing 1490 by 451, we get 3 with a remainder of 137.
Put 3 as the next digit of the answer. 
Result so far: 140890.4013
The remainder is 137 after subtracting 1353 from 1490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Let's proceed to step 13:
451 can be fit into 1370 3 times, resulting in a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 140890.40133
Deduct 1353 from 1370 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final result is 140890.40133 with a remainder of 1.7e-05.
