Let's divide 641896 by 4
Let's see how many times 4 fits into 641896.

Step 1:
If we divide 6 by 4, we get 1 and a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 4 from 6 to get 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 4

Advancing to step 2:
24 divided by 4 is 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 16.0
The remainder is 0 after subtracting 24 from 24.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 4

Step 3:
The number 4 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 160.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 4

On to step 4:
When dividing 18 by 4, we get 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 1604.0
Deduct 16 from 18 and we're left with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 4

On to step 5:
4 can be fit into 29 7 times, resulting in a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 16047.0
Subtracting 28 from 29 leaves us with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 4

On to step 6:
If we divide 16 by 4, we get 4 and a remainder of 0.
The next digit of our result is 4. 
Result so far: 160474.0
If we subtract 16 from 16, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 160474.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
When dividing 0 by 4, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 160474.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 160474.0, with a leftover of 0.0.
