We're dividing 10514510 by 643 
Let's see how many times 643 fits into 10514510.

Let's proceed to step 1:
When dividing 1 by 643, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 643

Step 2:
643 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Append the next digit (5) from the dividend to 10 and continue with: 105 / 643

Moving on to step 3:
If we divide 105 by 643, we get 0 and a remainder of 105.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 105 leaves us with 105.
Grab the next digit (1) from the dividend, add it to 105, then carry on: 1051 / 643

Let's proceed to step 4:
The number 643 fits into 1051 1 times, leaving a remainder of 408.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 408 after subtracting 643 from 1051.
Bring next digit (4) of the dividend behind the 408 and repeat the process: 4084 / 643

Going ahead to step 5:
4084 divided by 643 is 6 with a remainder of 226.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we take 3858 away from 4084, we end up with 226.
Include the next digit (5) from the dividend after 226, then repeat: 2265 / 643

Advancing to step 6:
2265 divided by 643 is 3 with a remainder of 336.
Put 3 as the next digit of the answer. 
Result so far: 163.0
Deduct 1929 from 2265 and we're left with 336.
Fetch the next digit (1) from the dividend, attach it to 336 and continue: 3361 / 643

Advancing to step 7:
The number 643 fits into 3361 5 times, leaving a remainder of 146.
The number 5 becomes the next digit in our result. 
Result so far: 1635.0
If we subtract 3215 from 3361, we get 146.
Fetch the next digit (0) from the dividend, attach it to 146 and continue: 1460 / 643

Let's proceed to step 8:
1460 divided by 643 is 2 with a remainder of 174.
Write down 2 as next digit of the result. 
Result so far: 16352.0
Deduct 1286 from 1460 and we're left with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Advancing to step 9:
When dividing 1740 by 643, we get 2 with a remainder of 454.
The number 2 becomes the next digit in our result. 
Result so far: 16352.2
The remainder is 454 after subtracting 1286 from 1740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

On to step 10:
When dividing 4540 by 643, we get 7 with a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 16352.27
Deduct 4501 from 4540 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 11:
If we divide 390 by 643, we get 0 and a remainder of 390.
Put 0 as the next digit of the answer. 
Result so far: 16352.27
Subtracting 0 from 390 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Advancing to step 12:
The number 643 fits into 3900 6 times, leaving a remainder of 42.
The number 6 becomes the next digit in our result. 
Result so far: 16352.2706
Subtract 3858 from 3900 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 13:
If we divide 420 by 643, we get 0 and a remainder of 420.
Use 0 as the next digit of our solution. 
Result so far: 16352.2706
Deduct 0 from 420 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Going ahead to step 14:
643 can be fit into 4200 6 times, resulting in a remainder of 342.
Put 6 as the next digit of the answer. 
Result so far: 16352.270606
Subtracting 3858 from 4200 leaves us with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

On to step 15:
The number 643 fits into 3420 5 times, leaving a remainder of 205.
The number 5 becomes the next digit in our result. 
Result so far: 16352.2706065
Subtracting 3215 from 3420 leaves us with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Advancing to step 16:
The number 643 fits into 2050 3 times, leaving a remainder of 121.
Put 3 as the next digit of the answer. 
Result so far: 16352.27060653
If we subtract 1929 from 2050, we get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

The final outcome is 16352.27060653, with a leftover of 1.21e-07.
