We look at the division of 34648642 by 643 
We're looking to find how many times 643 goes into 34648642.

On to step 1:
643 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 643

Going ahead to step 2:
643 can be fit into 34 0 times, resulting in a remainder of 34.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 34, we end up with 34.
Bring next digit (6) of the dividend behind the 34 and repeat the process: 346 / 643

Moving on to step 3:
When dividing 346 by 643, we get 0 with a remainder of 346.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 346 leaves us with 346.
Take the next digit (4) from the dividend and append it to 346, then repeat: 3464 / 643

On to step 4:
643 goes into 3464 5 times with a remainder of 249.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 3215 away from 3464, we end up with 249.
Include the next digit (8) from the dividend after 249, then repeat: 2498 / 643

Advancing to step 5:
The number 643 fits into 2498 3 times, leaving a remainder of 569.
Use 3 as the next digit of our solution. 
Result so far: 53.0
Subtract 1929 from 2498 to get 569.
Append the next digit (6) from the dividend to 569 and continue with: 5696 / 643

Let's proceed to step 6:
643 goes into 5696 8 times with a remainder of 552.
Write down 8 as next digit of the result. 
Result so far: 538.0
Subtract 5144 from 5696 to get 552.
Fetch the next digit (4) from the dividend, attach it to 552 and continue: 5524 / 643

Advancing to step 7:
If we divide 5524 by 643, we get 8 and a remainder of 380.
The next digit of our result is 8. 
Result so far: 5388.0
Subtract 5144 from 5524 to get 380.
Fetch the next digit (2) from the dividend, attach it to 380 and continue: 3802 / 643

Advancing to step 8:
643 goes into 3802 5 times with a remainder of 587.
Write down 5 as next digit of the result. 
Result so far: 53885.0
Deduct 3215 from 3802 and we're left with 587.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5870, and continue the process.

Step 9:
643 can be fit into 5870 9 times, resulting in a remainder of 83.
Write down 9 as next digit of the result. 
Result so far: 53885.9
Deduct 5787 from 5870 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 10:
643 can be fit into 830 1 times, resulting in a remainder of 187.
Use 1 as the next digit of our solution. 
Result so far: 53885.91
If we take 643 away from 830, we end up with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Step 11:
The number 643 fits into 1870 2 times, leaving a remainder of 584.
Put 2 as the next digit of the answer. 
Result so far: 53885.912
If we take 1286 away from 1870, we end up with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Advancing to step 12:
The number 643 fits into 5840 9 times, leaving a remainder of 53.
The next digit of our result is 9. 
Result so far: 53885.9129
If we subtract 5787 from 5840, 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.

Going ahead to step 13:
643 can be fit into 530 0 times, resulting in a remainder of 530.
Put 0 as the next digit of the answer. 
Result so far: 53885.9129
If we subtract 0 from 530, we get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Going ahead to step 14:
643 can be fit into 5300 8 times, resulting in a remainder of 156.
Write down 8 as next digit of the result. 
Result so far: 53885.912908
Subtract 5144 from 5300 to get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Let's proceed to step 15:
643 goes into 1560 2 times with a remainder of 274.
Put 2 as the next digit of the answer. 
Result so far: 53885.9129082
Subtracting 1286 from 1560 leaves us with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

On to step 16:
643 can be fit into 2740 4 times, resulting in a remainder of 168.
Use 4 as the next digit of our solution. 
Result so far: 53885.91290824
Deduct 2572 from 2740 and we're left with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Our division results in 53885.91290824 with a remaining 1.68e-07.
