We look at the division of 85163480 by 451 
Our goal is to divide 85163480 by 451.

Going ahead to step 1:
451 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 451

Advancing to step 2:
451 can be fit into 85 0 times, resulting in a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Bring next digit (1) of the dividend behind the 85 and repeat the process: 851 / 451

On to step 3:
The number 451 fits into 851 1 times, leaving a remainder of 400.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 451 from 851 leaves us with 400.
Fetch the next digit (6) from the dividend, attach it to 400 and continue: 4006 / 451

Moving on to step 4:
The number 451 fits into 4006 8 times, leaving a remainder of 398.
The next digit of our result is 8. 
Result so far: 18.0
Deduct 3608 from 4006 and we're left with 398.
Append the next digit (3) from the dividend to 398 and continue with: 3983 / 451

On to step 5:
When dividing 3983 by 451, we get 8 with a remainder of 375.
Use 8 as the next digit of our solution. 
Result so far: 188.0
Deduct 3608 from 3983 and we're left with 375.
Append the next digit (4) from the dividend to 375 and continue with: 3754 / 451

Going ahead to step 6:
451 goes into 3754 8 times with a remainder of 146.
Use 8 as the next digit of our solution. 
Result so far: 1888.0
If we take 3608 away from 3754, we end up with 146.
Include the next digit (8) from the dividend after 146, then repeat: 1468 / 451

Moving on to step 7:
451 can be fit into 1468 3 times, resulting in a remainder of 115.
Put 3 as the next digit of the answer. 
Result so far: 18883.0
Deduct 1353 from 1468 and we're left with 115.
Take the next digit (0) from the dividend and append it to 115, then repeat: 1150 / 451

Moving on to step 8:
451 goes into 1150 2 times with a remainder of 248.
The next digit of our result is 2. 
Result so far: 188832.0
Subtract 902 from 1150 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Going ahead to step 9:
451 can be fit into 2480 5 times, resulting in a remainder of 225.
Use 5 as the next digit of our solution. 
Result so far: 188832.5
The remainder is 225 after subtracting 2255 from 2480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Moving on to step 10:
451 goes into 2250 4 times with a remainder of 446.
Record the quotient 4 as the next digit in the result. 
Result so far: 188832.54
Deduct 1804 from 2250 and we're left with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Let's proceed to step 11:
The number 451 fits into 4460 9 times, leaving a remainder of 401.
The number 9 becomes the next digit in our result. 
Result so far: 188832.549
If we subtract 4059 from 4460, we get 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

On to step 12:
If we divide 4010 by 451, we get 8 and a remainder of 402.
Put 8 as the next digit of the answer. 
Result so far: 188832.5498
If we take 3608 away from 4010, we end up with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Advancing to step 13:
If we divide 4020 by 451, we get 8 and a remainder of 412.
Use 8 as the next digit of our solution. 
Result so far: 188832.54988
Subtract 3608 from 4020 to get 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Our division results in 188832.54988 with a remaining 0.000412.
