Let's divide 10693278 by 643
We want to divide 10693278 by 643.

Going ahead to step 1:
The number 643 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 643

Moving on to step 2:
643 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Take the next digit (6) from the dividend and append it to 10, then repeat: 106 / 643

Going ahead to step 3:
The number 643 fits into 106 0 times, leaving a remainder of 106.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 106 after subtracting 0 from 106.
Append the next digit (9) from the dividend to 106 and continue with: 1069 / 643

Step 4:
643 goes into 1069 1 times with a remainder of 426.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 643 from 1069 and we're left with 426.
Take the next digit (3) from the dividend and append it to 426, then repeat: 4263 / 643

Step 5:
4263 divided by 643 is 6 with a remainder of 405.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we subtract 3858 from 4263, we get 405.
Grab the next digit (2) from the dividend, add it to 405, then carry on: 4052 / 643

Advancing to step 6:
4052 divided by 643 is 6 with a remainder of 194.
Use 6 as the next digit of our solution. 
Result so far: 166.0
If we subtract 3858 from 4052, we get 194.
Take the next digit (7) from the dividend and append it to 194, then repeat: 1947 / 643

Advancing to step 7:
When dividing 1947 by 643, we get 3 with a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 1663.0
The remainder is 18 after subtracting 1929 from 1947.
Include the next digit (8) from the dividend after 18, then repeat: 188 / 643

Step 8:
If we divide 188 by 643, we get 0 and a remainder of 188.
The number 0 becomes the next digit in our result. 
Result so far: 16630.0
Deduct 0 from 188 and we're left with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Let's proceed to step 9:
643 can be fit into 1880 2 times, resulting in a remainder of 594.
Record the quotient 2 as the next digit in the result. 
Result so far: 16630.2
The remainder is 594 after subtracting 1286 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

On to step 10:
5940 divided by 643 is 9 with a remainder of 153.
The number 9 becomes the next digit in our result. 
Result so far: 16630.29
Subtracting 5787 from 5940 leaves us with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Advancing to step 11:
When dividing 1530 by 643, we get 2 with a remainder of 244.
Put 2 as the next digit of the answer. 
Result so far: 16630.292
Subtract 1286 from 1530 to get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Moving on to step 12:
If we divide 2440 by 643, we get 3 and a remainder of 511.
Put 3 as the next digit of the answer. 
Result so far: 16630.2923
If we subtract 1929 from 2440, we get 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

Step 13:
The number 643 fits into 5110 7 times, leaving a remainder of 609.
The next digit of our result is 7. 
Result so far: 16630.29237
If we take 4501 away from 5110, we end up with 609.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6090, and continue the process.

Going ahead to step 14:
643 can be fit into 6090 9 times, resulting in a remainder of 303.
Use 9 as the next digit of our solution. 
Result so far: 16630.292379
Deduct 5787 from 6090 and we're left with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

On to step 15:
If we divide 3030 by 643, we get 4 and a remainder of 458.
Record the quotient 4 as the next digit in the result. 
Result so far: 16630.2923794
If we subtract 2572 from 3030, we get 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

On to step 16:
If we divide 4580 by 643, we get 7 and a remainder of 79.
The next digit of our result is 7. 
Result so far: 16630.29237947
The remainder is 79 after subtracting 4501 from 4580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

After the division, we end up with 16630.29237947 and a remainder of 7.9e-08.
