We're dividing 68861346 by 451 
Our goal is to divide 68861346 by 451.

Moving on to step 1:
When dividing 6 by 451, we get 0 with 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.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 451

Advancing to step 2:
451 goes into 68 0 times with a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Include the next digit (8) from the dividend after 68, then repeat: 688 / 451

Let's proceed to step 3:
If we divide 688 by 451, we get 1 and a remainder of 237.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 451 from 688 and we're left with 237.
Fetch the next digit (6) from the dividend, attach it to 237 and continue: 2376 / 451

Let's proceed to step 4:
451 goes into 2376 5 times with a remainder of 121.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we take 2255 away from 2376, we end up with 121.
Include the next digit (1) from the dividend after 121, then repeat: 1211 / 451

Going ahead to step 5:
If we divide 1211 by 451, we get 2 and a remainder of 309.
Write down 2 as next digit of the result. 
Result so far: 152.0
Subtract 902 from 1211 to get 309.
Take the next digit (3) from the dividend and append it to 309, then repeat: 3093 / 451

Let's proceed to step 6:
451 goes into 3093 6 times with a remainder of 387.
The next digit of our result is 6. 
Result so far: 1526.0
Subtract 2706 from 3093 to get 387.
Include the next digit (4) from the dividend after 387, then repeat: 3874 / 451

Step 7:
451 goes into 3874 8 times with a remainder of 266.
Use 8 as the next digit of our solution. 
Result so far: 15268.0
If we take 3608 away from 3874, we end up with 266.
Include the next digit (6) from the dividend after 266, then repeat: 2666 / 451

Let's proceed to step 8:
451 goes into 2666 5 times with a remainder of 411.
Put 5 as the next digit of the answer. 
Result so far: 152685.0
If we take 2255 away from 2666, we end up with 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

Let's proceed to step 9:
If we divide 4110 by 451, we get 9 and a remainder of 51.
Write down 9 as next digit of the result. 
Result so far: 152685.9
If we take 4059 away from 4110, we end up with 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:
510 divided by 451 is 1 with a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 152685.91
If we take 451 away from 510, we end up 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:
When dividing 590 by 451, we get 1 with a remainder of 139.
Use 1 as the next digit of our solution. 
Result so far: 152685.911
Subtracting 451 from 590 leaves us with 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 quotient of the division is 152685.911, and the remainder is 0.0139.
