Let's divide 74243188 by 864
We want to figure out the number of times 74243188 can be divided by 864.

Going ahead to step 1:
864 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 864

Let's proceed to step 2:
74 divided by 864 is 0 with a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 74 after subtracting 0 from 74.
Bring next digit (2) of the dividend behind the 74 and repeat the process: 742 / 864

Advancing to step 3:
742 divided by 864 is 0 with a remainder of 742.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 742 and we're left with 742.
Grab the next digit (4) from the dividend, add it to 742, then carry on: 7424 / 864

Advancing to step 4:
The number 864 fits into 7424 8 times, leaving a remainder of 512.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 6912 from 7424 and we're left with 512.
Fetch the next digit (3) from the dividend, attach it to 512 and continue: 5123 / 864

Going ahead to step 5:
When dividing 5123 by 864, we get 5 with a remainder of 803.
The next digit of our result is 5. 
Result so far: 85.0
If we subtract 4320 from 5123, we get 803.
Grab the next digit (1) from the dividend, add it to 803, then carry on: 8031 / 864

Moving on to step 6:
864 can be fit into 8031 9 times, resulting in a remainder of 255.
Record the quotient 9 as the next digit in the result. 
Result so far: 859.0
Subtracting 7776 from 8031 leaves us with 255.
Include the next digit (8) from the dividend after 255, then repeat: 2558 / 864

Let's proceed to step 7:
864 goes into 2558 2 times with a remainder of 830.
Use 2 as the next digit of our solution. 
Result so far: 8592.0
Subtracting 1728 from 2558 leaves us with 830.
Include the next digit (8) from the dividend after 830, then repeat: 8308 / 864

On to step 8:
864 can be fit into 8308 9 times, resulting in a remainder of 532.
Record the quotient 9 as the next digit in the result. 
Result so far: 85929.0
Deduct 7776 from 8308 and we're left with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

On to step 9:
864 can be fit into 5320 6 times, resulting in a remainder of 136.
Write down 6 as next digit of the result. 
Result so far: 85929.6
The remainder is 136 after subtracting 5184 from 5320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

On to step 10:
When dividing 1360 by 864, we get 1 with a remainder of 496.
Use 1 as the next digit of our solution. 
Result so far: 85929.61
If we take 864 away from 1360, we end up with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Advancing to step 11:
864 goes into 4960 5 times with a remainder of 640.
Write down 5 as next digit of the result. 
Result so far: 85929.615
The remainder is 640 after subtracting 4320 from 4960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

On to step 12:
The number 864 fits into 6400 7 times, leaving a remainder of 352.
Record the quotient 7 as the next digit in the result. 
Result so far: 85929.6157
Subtract 6048 from 6400 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

On to step 13:
The number 864 fits into 3520 4 times, leaving a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 85929.61574
Subtract 3456 from 3520 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 14:
If we divide 640 by 864, we get 0 and a remainder of 640.
The number 0 becomes the next digit in our result. 
Result so far: 85929.61574
Subtract 0 from 640 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Advancing to step 15:
864 goes into 6400 7 times with a remainder of 352.
Write down 7 as next digit of the result. 
Result so far: 85929.6157407
The remainder is 352 after subtracting 6048 from 6400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Going ahead to step 16:
864 goes into 3520 4 times with a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 85929.61574074
If we take 3456 away from 3520, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 85929.61574074 with a remainder of 6.4e-08.
