We're dividing 12407155 by 862 
We want to figure out the number of times 12407155 can be divided by 862.

Step 1:
862 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 862

On to step 2:
862 can be fit into 12 0 times, resulting in a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 862

Let's proceed to step 3:
When dividing 124 by 862, we get 0 with a remainder of 124.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 124 leaves us with 124.
Include the next digit (0) from the dividend after 124, then repeat: 1240 / 862

Going ahead to step 4:
862 can be fit into 1240 1 times, resulting in a remainder of 378.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 862 away from 1240, we end up with 378.
Append the next digit (7) from the dividend to 378 and continue with: 3787 / 862

On to step 5:
862 goes into 3787 4 times with a remainder of 339.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we take 3448 away from 3787, we end up with 339.
Include the next digit (1) from the dividend after 339, then repeat: 3391 / 862

Let's proceed to step 6:
3391 divided by 862 is 3 with a remainder of 805.
Write down 3 as next digit of the result. 
Result so far: 143.0
If we take 2586 away from 3391, we end up with 805.
Bring next digit (5) of the dividend behind the 805 and repeat the process: 8055 / 862

Let's proceed to step 7:
If we divide 8055 by 862, we get 9 and a remainder of 297.
The number 9 becomes the next digit in our result. 
Result so far: 1439.0
Deduct 7758 from 8055 and we're left with 297.
Take the next digit (5) from the dividend and append it to 297, then repeat: 2975 / 862

Moving on to step 8:
862 can be fit into 2975 3 times, resulting in a remainder of 389.
Record the quotient 3 as the next digit in the result. 
Result so far: 14393.0
If we take 2586 away from 2975, we end up with 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Moving on to step 9:
The number 862 fits into 3890 4 times, leaving a remainder of 442.
Write down 4 as next digit of the result. 
Result so far: 14393.4
Subtract 3448 from 3890 to get 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Moving on to step 10:
If we divide 4420 by 862, we get 5 and a remainder of 110.
The next digit of our result is 5. 
Result so far: 14393.45
Deduct 4310 from 4420 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 11:
The number 862 fits into 1100 1 times, leaving a remainder of 238.
The number 1 becomes the next digit in our result. 
Result so far: 14393.451
Subtract 862 from 1100 to get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Going ahead to step 12:
If we divide 2380 by 862, we get 2 and a remainder of 656.
Record the quotient 2 as the next digit in the result. 
Result so far: 14393.4512
If we take 1724 away from 2380, we end up with 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Moving on to step 13:
If we divide 6560 by 862, we get 7 and a remainder of 526.
Put 7 as the next digit of the answer. 
Result so far: 14393.45127
Deduct 6034 from 6560 and we're left with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Step 14:
When dividing 5260 by 862, we get 6 with a remainder of 88.
The number 6 becomes the next digit in our result. 
Result so far: 14393.451276
Subtract 5172 from 5260 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 15:
The number 862 fits into 880 1 times, leaving a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 14393.4512761
If we subtract 862 from 880, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 16:
If we divide 180 by 862, we get 0 and a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 14393.4512761
Subtracting 0 from 180 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

In conclusion, the division gives 14393.4512761 with a balance of 1.8e-07.
