Let's divide 78247801 by 454
We want to divide 78247801 by 454.

Moving on to step 1:
If we divide 7 by 454, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 454

Moving on to step 2:
454 goes into 78 0 times with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Append the next digit (2) from the dividend to 78 and continue with: 782 / 454

Advancing to step 3:
The number 454 fits into 782 1 times, leaving a remainder of 328.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 454 from 782 and we're left with 328.
Bring next digit (4) of the dividend behind the 328 and repeat the process: 3284 / 454

Advancing to step 4:
If we divide 3284 by 454, we get 7 and a remainder of 106.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtract 3178 from 3284 to get 106.
Grab the next digit (7) from the dividend, add it to 106, then carry on: 1067 / 454

Moving on to step 5:
If we divide 1067 by 454, we get 2 and a remainder of 159.
Use 2 as the next digit of our solution. 
Result so far: 172.0
Deduct 908 from 1067 and we're left with 159.
Bring next digit (8) of the dividend behind the 159 and repeat the process: 1598 / 454

Going ahead to step 6:
1598 divided by 454 is 3 with a remainder of 236.
Put 3 as the next digit of the answer. 
Result so far: 1723.0
If we take 1362 away from 1598, we end up with 236.
Grab the next digit (0) from the dividend, add it to 236, then carry on: 2360 / 454

Let's proceed to step 7:
454 goes into 2360 5 times with a remainder of 90.
Record the quotient 5 as the next digit in the result. 
Result so far: 17235.0
If we subtract 2270 from 2360, we get 90.
Append the next digit (1) from the dividend to 90 and continue with: 901 / 454

Moving on to step 8:
901 divided by 454 is 1 with a remainder of 447.
The next digit of our result is 1. 
Result so far: 172351.0
Subtracting 454 from 901 leaves us with 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Going ahead to step 9:
If we divide 4470 by 454, we get 9 and a remainder of 384.
The number 9 becomes the next digit in our result. 
Result so far: 172351.9
The remainder is 384 after subtracting 4086 from 4470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

On to step 10:
3840 divided by 454 is 8 with a remainder of 208.
Record the quotient 8 as the next digit in the result. 
Result so far: 172351.98
Subtracting 3632 from 3840 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 11:
2080 divided by 454 is 4 with a remainder of 264.
The number 4 becomes the next digit in our result. 
Result so far: 172351.984
Subtract 1816 from 2080 to get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Advancing to step 12:
If we divide 2640 by 454, we get 5 and a remainder of 370.
The number 5 becomes the next digit in our result. 
Result so far: 172351.9845
The remainder is 370 after subtracting 2270 from 2640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 13:
3700 divided by 454 is 8 with a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 172351.98458
Subtracting 3632 from 3700 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 14:
454 goes into 680 1 times with a remainder of 226.
Use 1 as the next digit of our solution. 
Result so far: 172351.984581
If we subtract 454 from 680, we get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Step 15:
454 can be fit into 2260 4 times, resulting in a remainder of 444.
Write down 4 as next digit of the result. 
Result so far: 172351.9845814
Deduct 1816 from 2260 and we're left with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Going ahead to step 16:
If we divide 4440 by 454, we get 9 and a remainder of 354.
The number 9 becomes the next digit in our result. 
Result so far: 172351.98458149
Deduct 4086 from 4440 and we're left with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Our division results in 172351.98458149 with a remaining 3.54e-07.
