We look at the division of 5446037 by 643 
We're looking to find how many times 643 goes into 5446037.

On to step 1:
If we divide 5 by 643, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 643

Going ahead to step 2:
When dividing 54 by 643, we get 0 with a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Grab the next digit (4) from the dividend, add it to 54, then carry on: 544 / 643

On to step 3:
When dividing 544 by 643, we get 0 with a remainder of 544.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 544 after subtracting 0 from 544.
Take the next digit (6) from the dividend and append it to 544, then repeat: 5446 / 643

Going ahead to step 4:
If we divide 5446 by 643, we get 8 and a remainder of 302.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 5144 from 5446 and we're left with 302.
Bring next digit (0) of the dividend behind the 302 and repeat the process: 3020 / 643

Advancing to step 5:
The number 643 fits into 3020 4 times, leaving a remainder of 448.
The next digit of our result is 4. 
Result so far: 84.0
Deduct 2572 from 3020 and we're left with 448.
Fetch the next digit (3) from the dividend, attach it to 448 and continue: 4483 / 643

On to step 6:
If we divide 4483 by 643, we get 6 and a remainder of 625.
The next digit of our result is 6. 
Result so far: 846.0
If we subtract 3858 from 4483, we get 625.
Include the next digit (7) from the dividend after 625, then repeat: 6257 / 643

Advancing to step 7:
The number 643 fits into 6257 9 times, leaving a remainder of 470.
Write down 9 as next digit of the result. 
Result so far: 8469.0
Subtracting 5787 from 6257 leaves us with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Let's proceed to step 8:
The number 643 fits into 4700 7 times, leaving a remainder of 199.
Put 7 as the next digit of the answer. 
Result so far: 8469.7
If we subtract 4501 from 4700, we get 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Let's proceed to step 9:
The number 643 fits into 1990 3 times, leaving a remainder of 61.
Put 3 as the next digit of the answer. 
Result so far: 8469.73
If we subtract 1929 from 1990, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 10:
The number 643 fits into 610 0 times, leaving a remainder of 610.
Record the quotient 0 as the next digit in the result. 
Result so far: 8469.73
If we take 0 away from 610, we end up with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

On to step 11:
643 goes into 6100 9 times with a remainder of 313.
Put 9 as the next digit of the answer. 
Result so far: 8469.7309
Deduct 5787 from 6100 and we're left with 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

On to step 12:
When dividing 3130 by 643, we get 4 with a remainder of 558.
The number 4 becomes the next digit in our result. 
Result so far: 8469.73094
Subtract 2572 from 3130 to get 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Moving on to step 13:
643 goes into 5580 8 times with a remainder of 436.
The next digit of our result is 8. 
Result so far: 8469.730948
Deduct 5144 from 5580 and we're left with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Let's proceed to step 14:
When dividing 4360 by 643, we get 6 with a remainder of 502.
The next digit of our result is 6. 
Result so far: 8469.7309486
If we take 3858 away from 4360, we end up with 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

On to step 15:
The number 643 fits into 5020 7 times, leaving a remainder of 519.
Put 7 as the next digit of the answer. 
Result so far: 8469.73094867
Subtract 4501 from 5020 to get 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

The final result is 8469.73094867 with a remainder of 5.19e-07.
