3462437 ÷ 644 
Let's see how many times 644 fits into 3462437.

Going ahead to step 1:
When dividing 3 by 644, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 644

Step 2:
644 can be fit into 34 0 times, resulting in a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 34, we end up with 34.
Take the next digit (6) from the dividend and append it to 34, then repeat: 346 / 644

Step 3:
The number 644 fits into 346 0 times, leaving a remainder of 346.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 346 after subtracting 0 from 346.
Fetch the next digit (2) from the dividend, attach it to 346 and continue: 3462 / 644

Let's proceed to step 4:
644 can be fit into 3462 5 times, resulting in a remainder of 242.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 242 after subtracting 3220 from 3462.
Bring next digit (4) of the dividend behind the 242 and repeat the process: 2424 / 644

Going ahead to step 5:
When dividing 2424 by 644, we get 3 with a remainder of 492.
Write down 3 as next digit of the result. 
Result so far: 53.0
If we subtract 1932 from 2424, we get 492.
Bring next digit (3) of the dividend behind the 492 and repeat the process: 4923 / 644

Step 6:
4923 divided by 644 is 7 with a remainder of 415.
Use 7 as the next digit of our solution. 
Result so far: 537.0
If we subtract 4508 from 4923, we get 415.
Bring next digit (7) of the dividend behind the 415 and repeat the process: 4157 / 644

Moving on to step 7:
644 goes into 4157 6 times with a remainder of 293.
Put 6 as the next digit of the answer. 
Result so far: 5376.0
Subtracting 3864 from 4157 leaves us with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Step 8:
644 can be fit into 2930 4 times, resulting in a remainder of 354.
Write down 4 as next digit of the result. 
Result so far: 5376.4
The remainder is 354 after subtracting 2576 from 2930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Step 9:
The number 644 fits into 3540 5 times, leaving a remainder of 320.
The number 5 becomes the next digit in our result. 
Result so far: 5376.45
Deduct 3220 from 3540 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 10:
The number 644 fits into 3200 4 times, leaving a remainder of 624.
Record the quotient 4 as the next digit in the result. 
Result so far: 5376.454
Deduct 2576 from 3200 and we're left with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Let's proceed to step 11:
When dividing 6240 by 644, we get 9 with a remainder of 444.
The next digit of our result is 9. 
Result so far: 5376.4549
If we take 5796 away from 6240, we end up with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Advancing to step 12:
When dividing 4440 by 644, we get 6 with a remainder of 576.
The next digit of our result is 6. 
Result so far: 5376.45496
If we take 3864 away from 4440, we end up with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

On to step 13:
5760 divided by 644 is 8 with a remainder of 608.
The next digit of our result is 8. 
Result so far: 5376.454968
Subtracting 5152 from 5760 leaves us with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Moving on to step 14:
The number 644 fits into 6080 9 times, leaving a remainder of 284.
Use 9 as the next digit of our solution. 
Result so far: 5376.4549689
Deduct 5796 from 6080 and we're left with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

On to step 15:
2840 divided by 644 is 4 with a remainder of 264.
Write down 4 as next digit of the result. 
Result so far: 5376.45496894
If we subtract 2576 from 2840, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

The final outcome is 5376.45496894, with a leftover of 2.64e-07.
