643148 ÷ 93 
Let's see how many times 93 fits into 643148.

On to step 1:
When dividing 6 by 93, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 93

On to step 2:
93 can be fit into 64 0 times, resulting in a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Include the next digit (3) from the dividend after 64, then repeat: 643 / 93

On to step 3:
643 divided by 93 is 6 with a remainder of 85.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 558 from 643 to get 85.
Take the next digit (1) from the dividend and append it to 85, then repeat: 851 / 93

Moving on to step 4:
If we divide 851 by 93, we get 9 and a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 69.0
Deduct 837 from 851 and we're left with 14.
Append the next digit (4) from the dividend to 14 and continue with: 144 / 93

Moving on to step 5:
93 goes into 144 1 times with a remainder of 51.
Use 1 as the next digit of our solution. 
Result so far: 691.0
The remainder is 51 after subtracting 93 from 144.
Fetch the next digit (8) from the dividend, attach it to 51 and continue: 518 / 93

On to step 6:
518 divided by 93 is 5 with a remainder of 53.
Write down 5 as next digit of the result. 
Result so far: 6915.0
If we subtract 465 from 518, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 7:
530 divided by 93 is 5 with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 6915.5
The remainder is 65 after subtracting 465 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 8:
When dividing 650 by 93, we get 6 with a remainder of 92.
Use 6 as the next digit of our solution. 
Result so far: 6915.56
The remainder is 92 after subtracting 558 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 9:
If we divide 920 by 93, we get 9 and a remainder of 83.
Put 9 as the next digit of the answer. 
Result so far: 6915.569
The remainder is 83 after subtracting 837 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 10:
93 can be fit into 830 8 times, resulting in a remainder of 86.
Put 8 as the next digit of the answer. 
Result so far: 6915.5698
The remainder is 86 after subtracting 744 from 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 11:
860 divided by 93 is 9 with a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 6915.56989
Deduct 837 from 860 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 12:
If we divide 230 by 93, we get 2 and a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 6915.569892
Deduct 186 from 230 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 13:
When dividing 440 by 93, we get 4 with a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 6915.5698924
If we subtract 372 from 440, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 14:
93 can be fit into 680 7 times, resulting in a remainder of 29.
Put 7 as the next digit of the answer. 
Result so far: 6915.56989247
Deduct 651 from 680 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

In conclusion, the division gives 6915.56989247 with a balance of 2.9e-08.
