We look at the division of 76145898 by 451 
We're looking to find how many times 451 goes into 76145898.

On to step 1:
451 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 451

Moving on to step 2:
451 can be fit into 76 0 times, resulting in a remainder of 76.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Append the next digit (1) from the dividend to 76 and continue with: 761 / 451

On to step 3:
761 divided by 451 is 1 with a remainder of 310.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 451 from 761 to get 310.
Grab the next digit (4) from the dividend, add it to 310, then carry on: 3104 / 451

Step 4:
451 goes into 3104 6 times with a remainder of 398.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we take 2706 away from 3104, we end up with 398.
Take the next digit (5) from the dividend and append it to 398, then repeat: 3985 / 451

Step 5:
451 can be fit into 3985 8 times, resulting in a remainder of 377.
The number 8 becomes the next digit in our result. 
Result so far: 168.0
Deduct 3608 from 3985 and we're left with 377.
Fetch the next digit (8) from the dividend, attach it to 377 and continue: 3778 / 451

Going ahead to step 6:
The number 451 fits into 3778 8 times, leaving a remainder of 170.
The number 8 becomes the next digit in our result. 
Result so far: 1688.0
If we take 3608 away from 3778, we end up with 170.
Include the next digit (9) from the dividend after 170, then repeat: 1709 / 451

Moving on to step 7:
If we divide 1709 by 451, we get 3 and a remainder of 356.
Put 3 as the next digit of the answer. 
Result so far: 16883.0
Subtracting 1353 from 1709 leaves us with 356.
Append the next digit (8) from the dividend to 356 and continue with: 3568 / 451

Step 8:
451 goes into 3568 7 times with a remainder of 411.
The next digit of our result is 7. 
Result so far: 168837.0
If we subtract 3157 from 3568, we get 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

Going ahead to step 9:
When dividing 4110 by 451, we get 9 with a remainder of 51.
The next digit of our result is 9. 
Result so far: 168837.9
If we subtract 4059 from 4110, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 10:
If we divide 510 by 451, we get 1 and a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 168837.91
Subtracting 451 from 510 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 11:
If we divide 590 by 451, we get 1 and a remainder of 139.
Record the quotient 1 as the next digit in the result. 
Result so far: 168837.911
Subtract 451 from 590 to get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

The final result is 168837.911 with a remainder of 0.0139.
