We look at the division of 61519064 by 864 
We're looking to find how many times 864 goes into 61519064.

Step 1:
When dividing 6 by 864, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 864

Moving on to step 2:
864 can be fit into 61 0 times, resulting in a remainder of 61.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 61, we get 61.
Append the next digit (5) from the dividend to 61 and continue with: 615 / 864

On to step 3:
When dividing 615 by 864, we get 0 with a remainder of 615.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 615 to get 615.
Include the next digit (1) from the dividend after 615, then repeat: 6151 / 864

Step 4:
The number 864 fits into 6151 7 times, leaving a remainder of 103.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 6048 from 6151, we get 103.
Grab the next digit (9) from the dividend, add it to 103, then carry on: 1039 / 864

Going ahead to step 5:
When dividing 1039 by 864, we get 1 with a remainder of 175.
The next digit of our result is 1. 
Result so far: 71.0
Subtracting 864 from 1039 leaves us with 175.
Bring next digit (0) of the dividend behind the 175 and repeat the process: 1750 / 864

Advancing to step 6:
When dividing 1750 by 864, we get 2 with a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 712.0
If we subtract 1728 from 1750, we get 22.
Include the next digit (6) from the dividend after 22, then repeat: 226 / 864

Going ahead to step 7:
If we divide 226 by 864, we get 0 and a remainder of 226.
Write down 0 as next digit of the result. 
Result so far: 7120.0
If we subtract 0 from 226, we get 226.
Grab the next digit (4) from the dividend, add it to 226, then carry on: 2264 / 864

Step 8:
864 goes into 2264 2 times with a remainder of 536.
The number 2 becomes the next digit in our result. 
Result so far: 71202.0
Subtract 1728 from 2264 to get 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Going ahead to step 9:
The number 864 fits into 5360 6 times, leaving a remainder of 176.
Put 6 as the next digit of the answer. 
Result so far: 71202.6
Deduct 5184 from 5360 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 10:
The number 864 fits into 1760 2 times, leaving a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 71202.62
If we take 1728 away from 1760, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 11:
864 goes into 320 0 times with a remainder of 320.
The next digit of our result is 0. 
Result so far: 71202.62
The remainder is 320 after subtracting 0 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 12:
If we divide 3200 by 864, we get 3 and a remainder of 608.
The number 3 becomes the next digit in our result. 
Result so far: 71202.6203
Subtracting 2592 from 3200 leaves us with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Moving on to step 13:
6080 divided by 864 is 7 with a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 71202.62037
Deduct 6048 from 6080 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 14:
864 goes into 320 0 times with a remainder of 320.
Write down 0 as next digit of the result. 
Result so far: 71202.62037
If we subtract 0 from 320, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 15:
864 goes into 3200 3 times with a remainder of 608.
Record the quotient 3 as the next digit in the result. 
Result so far: 71202.6203703
If we subtract 2592 from 3200, we get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Going ahead to step 16:
864 goes into 6080 7 times with a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 71202.62037037
The remainder is 32 after subtracting 6048 from 6080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 71202.62037037 with a balance of 3.2e-08.
