We're dividing 7861167 by 256 
We want to figure out the number of times 7861167 can be divided by 256.

On to step 1:
When dividing 7 by 256, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 256

On to step 2:
256 can be fit into 78 0 times, resulting in a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Fetch the next digit (6) from the dividend, attach it to 78 and continue: 786 / 256

Going ahead to step 3:
256 goes into 786 3 times with a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 768 from 786, we get 18.
Append the next digit (1) from the dividend to 18 and continue with: 181 / 256

On to step 4:
The number 256 fits into 181 0 times, leaving a remainder of 181.
Use 0 as the next digit of our solution. 
Result so far: 30.0
Subtracting 0 from 181 leaves us with 181.
Append the next digit (1) from the dividend to 181 and continue with: 1811 / 256

Moving on to step 5:
256 can be fit into 1811 7 times, resulting in a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 307.0
If we take 1792 away from 1811, we end up with 19.
Append the next digit (6) from the dividend to 19 and continue with: 196 / 256

Advancing to step 6:
256 goes into 196 0 times with a remainder of 196.
Put 0 as the next digit of the answer. 
Result so far: 3070.0
If we subtract 0 from 196, we get 196.
Take the next digit (7) from the dividend and append it to 196, then repeat: 1967 / 256

Step 7:
256 goes into 1967 7 times with a remainder of 175.
Record the quotient 7 as the next digit in the result. 
Result so far: 30707.0
Deduct 1792 from 1967 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Step 8:
The number 256 fits into 1750 6 times, leaving a remainder of 214.
Write down 6 as next digit of the result. 
Result so far: 30707.6
Subtracting 1536 from 1750 leaves us with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Going ahead to step 9:
The number 256 fits into 2140 8 times, leaving a remainder of 92.
The number 8 becomes the next digit in our result. 
Result so far: 30707.68
If we subtract 2048 from 2140, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 10:
The number 256 fits into 920 3 times, leaving a remainder of 152.
Put 3 as the next digit of the answer. 
Result so far: 30707.683
If we subtract 768 from 920, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 11:
256 goes into 1520 5 times with a remainder of 240.
The number 5 becomes the next digit in our result. 
Result so far: 30707.6835
The remainder is 240 after subtracting 1280 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 12:
256 goes into 2400 9 times with a remainder of 96.
Write down 9 as next digit of the result. 
Result so far: 30707.68359
If we subtract 2304 from 2400, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 13:
The number 256 fits into 960 3 times, leaving a remainder of 192.
Use 3 as the next digit of our solution. 
Result so far: 30707.683593
Deduct 768 from 960 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 14:
256 goes into 1920 7 times with a remainder of 128.
Put 7 as the next digit of the answer. 
Result so far: 30707.6835937
The remainder is 128 after subtracting 1792 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 15:
256 can be fit into 1280 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 30707.68359375
If we take 1280 away from 1280, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 30707.68359375, with a leftover of 0.0.
