74521697 divided by 864 
Let's see how many times 864 fits into 74521697.

Let's proceed to step 1:
864 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 864

Moving on to step 2:
864 can be fit into 74 0 times, resulting in 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.
Fetch the next digit (5) from the dividend, attach it to 74 and continue: 745 / 864

Step 3:
745 divided by 864 is 0 with a remainder of 745.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 745 leaves us with 745.
Include the next digit (2) from the dividend after 745, then repeat: 7452 / 864

On to step 4:
864 goes into 7452 8 times with a remainder of 540.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 6912 from 7452 leaves us with 540.
Include the next digit (1) from the dividend after 540, then repeat: 5401 / 864

Moving on to step 5:
The number 864 fits into 5401 6 times, leaving a remainder of 217.
Put 6 as the next digit of the answer. 
Result so far: 86.0
Deduct 5184 from 5401 and we're left with 217.
Append the next digit (6) from the dividend to 217 and continue with: 2176 / 864

Step 6:
864 can be fit into 2176 2 times, resulting in a remainder of 448.
Write down 2 as next digit of the result. 
Result so far: 862.0
Subtract 1728 from 2176 to get 448.
Append the next digit (9) from the dividend to 448 and continue with: 4489 / 864

Advancing to step 7:
864 goes into 4489 5 times with a remainder of 169.
Write down 5 as next digit of the result. 
Result so far: 8625.0
Subtracting 4320 from 4489 leaves us with 169.
Grab the next digit (7) from the dividend, add it to 169, then carry on: 1697 / 864

Step 8:
The number 864 fits into 1697 1 times, leaving a remainder of 833.
Write down 1 as next digit of the result. 
Result so far: 86251.0
If we subtract 864 from 1697, we get 833.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8330, and continue the process.

Step 9:
If we divide 8330 by 864, we get 9 and a remainder of 554.
Record the quotient 9 as the next digit in the result. 
Result so far: 86251.9
Subtract 7776 from 8330 to get 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Step 10:
When dividing 5540 by 864, we get 6 with a remainder of 356.
The number 6 becomes the next digit in our result. 
Result so far: 86251.96
If we subtract 5184 from 5540, we get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Moving on to step 11:
3560 divided by 864 is 4 with a remainder of 104.
Use 4 as the next digit of our solution. 
Result so far: 86251.964
Subtract 3456 from 3560 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 12:
864 goes into 1040 1 times with a remainder of 176.
The number 1 becomes the next digit in our result. 
Result so far: 86251.9641
If we take 864 away from 1040, we end up 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.

Going ahead to step 13:
864 goes into 1760 2 times with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 86251.96412
Subtract 1728 from 1760 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 14:
When dividing 320 by 864, we get 0 with a remainder of 320.
Record the quotient 0 as the next digit in the result. 
Result so far: 86251.96412
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.

Let's proceed to step 15:
864 can be fit into 3200 3 times, resulting in a remainder of 608.
The number 3 becomes the next digit in our result. 
Result so far: 86251.9641203
The remainder is 608 after subtracting 2592 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Step 16:
6080 divided by 864 is 7 with a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 86251.96412037
If we take 6048 away from 6080, 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.

The final outcome is 86251.96412037, with a leftover of 3.2e-08.
