We look at the division of 34207166 by 864 
We want to figure out the number of times 34207166 can be divided by 864.

Step 1:
The number 864 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 864

Moving on to step 2:
34 divided by 864 is 0 with a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 34 after subtracting 0 from 34.
Grab the next digit (2) from the dividend, add it to 34, then carry on: 342 / 864

Moving on to step 3:
When dividing 342 by 864, we get 0 with a remainder of 342.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 342 to get 342.
Grab the next digit (0) from the dividend, add it to 342, then carry on: 3420 / 864

Let's proceed to step 4:
The number 864 fits into 3420 3 times, leaving a remainder of 828.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 2592 from 3420 to get 828.
Fetch the next digit (7) from the dividend, attach it to 828 and continue: 8287 / 864

Let's proceed to step 5:
The number 864 fits into 8287 9 times, leaving a remainder of 511.
The next digit of our result is 9. 
Result so far: 39.0
Subtracting 7776 from 8287 leaves us with 511.
Bring next digit (1) of the dividend behind the 511 and repeat the process: 5111 / 864

On to step 6:
When dividing 5111 by 864, we get 5 with a remainder of 791.
The number 5 becomes the next digit in our result. 
Result so far: 395.0
Subtract 4320 from 5111 to get 791.
Bring next digit (6) of the dividend behind the 791 and repeat the process: 7916 / 864

Moving on to step 7:
If we divide 7916 by 864, we get 9 and a remainder of 140.
The number 9 becomes the next digit in our result. 
Result so far: 3959.0
If we subtract 7776 from 7916, we get 140.
Append the next digit (6) from the dividend to 140 and continue with: 1406 / 864

Advancing to step 8:
864 goes into 1406 1 times with a remainder of 542.
Use 1 as the next digit of our solution. 
Result so far: 39591.0
Subtract 864 from 1406 to get 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Let's proceed to step 9:
The number 864 fits into 5420 6 times, leaving a remainder of 236.
Use 6 as the next digit of our solution. 
Result so far: 39591.6
Subtracting 5184 from 5420 leaves us with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Step 10:
864 can be fit into 2360 2 times, resulting in a remainder of 632.
Use 2 as the next digit of our solution. 
Result so far: 39591.62
Deduct 1728 from 2360 and we're left with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Advancing to step 11:
864 can be fit into 6320 7 times, resulting in a remainder of 272.
Record the quotient 7 as the next digit in the result. 
Result so far: 39591.627
The remainder is 272 after subtracting 6048 from 6320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Going ahead to step 12:
When dividing 2720 by 864, we get 3 with a remainder of 128.
Put 3 as the next digit of the answer. 
Result so far: 39591.6273
The remainder is 128 after subtracting 2592 from 2720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 13:
1280 divided by 864 is 1 with a remainder of 416.
Use 1 as the next digit of our solution. 
Result so far: 39591.62731
If we take 864 away from 1280, we end up with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

On to step 14:
4160 divided by 864 is 4 with a remainder of 704.
Write down 4 as next digit of the result. 
Result so far: 39591.627314
Deduct 3456 from 4160 and we're left with 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Moving on to step 15:
7040 divided by 864 is 8 with a remainder of 128.
Use 8 as the next digit of our solution. 
Result so far: 39591.6273148
Subtract 6912 from 7040 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 16:
864 can be fit into 1280 1 times, resulting in a remainder of 416.
The next digit of our result is 1. 
Result so far: 39591.62731481
If we subtract 864 from 1280, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

The final result is 39591.62731481 with a remainder of 4.16e-07.
