We divide 60405459 by 646
We're looking to find how many times 646 goes into 60405459.

Going ahead to step 1:
646 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 646

Advancing to step 2:
When dividing 60 by 646, we get 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 60 leaves us with 60.
Fetch the next digit (4) from the dividend, attach it to 60 and continue: 604 / 646

Advancing to step 3:
When dividing 604 by 646, we get 0 with a remainder of 604.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 604 to get 604.
Fetch the next digit (0) from the dividend, attach it to 604 and continue: 6040 / 646

Advancing to step 4:
When dividing 6040 by 646, we get 9 with a remainder of 226.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 5814 away from 6040, we end up with 226.
Include the next digit (5) from the dividend after 226, then repeat: 2265 / 646

Let's proceed to step 5:
646 can be fit into 2265 3 times, resulting in a remainder of 327.
Write down 3 as next digit of the result. 
Result so far: 93.0
The remainder is 327 after subtracting 1938 from 2265.
Grab the next digit (4) from the dividend, add it to 327, then carry on: 3274 / 646

Going ahead to step 6:
If we divide 3274 by 646, we get 5 and a remainder of 44.
Record the quotient 5 as the next digit in the result. 
Result so far: 935.0
Subtract 3230 from 3274 to get 44.
Fetch the next digit (5) from the dividend, attach it to 44 and continue: 445 / 646

On to step 7:
445 divided by 646 is 0 with a remainder of 445.
Record the quotient 0 as the next digit in the result. 
Result so far: 9350.0
Subtract 0 from 445 to get 445.
Include the next digit (9) from the dividend after 445, then repeat: 4459 / 646

Advancing to step 8:
646 can be fit into 4459 6 times, resulting in a remainder of 583.
Use 6 as the next digit of our solution. 
Result so far: 93506.0
If we subtract 3876 from 4459, we get 583.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5830, and continue the process.

Let's proceed to step 9:
If we divide 5830 by 646, we get 9 and a remainder of 16.
Use 9 as the next digit of our solution. 
Result so far: 93506.9
Subtracting 5814 from 5830 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
If we divide 160 by 646, we get 0 and a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 93506.9
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 11:
646 goes into 1600 2 times with a remainder of 308.
The next digit of our result is 2. 
Result so far: 93506.902
Deduct 1292 from 1600 and we're left with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Moving on to step 12:
If we divide 3080 by 646, we get 4 and a remainder of 496.
The next digit of our result is 4. 
Result so far: 93506.9024
Subtract 2584 from 3080 to get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Step 13:
4960 divided by 646 is 7 with a remainder of 438.
Record the quotient 7 as the next digit in the result. 
Result so far: 93506.90247
Subtract 4522 from 4960 to get 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Let's proceed to step 14:
If we divide 4380 by 646, we get 6 and a remainder of 504.
The next digit of our result is 6. 
Result so far: 93506.902476
Deduct 3876 from 4380 and we're left with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Advancing to step 15:
5040 divided by 646 is 7 with a remainder of 518.
Record the quotient 7 as the next digit in the result. 
Result so far: 93506.9024767
If we take 4522 away from 5040, we end up with 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Step 16:
646 can be fit into 5180 8 times, resulting in a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 93506.90247678
Deduct 5168 from 5180 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 93506.90247678 with a remainder of 1.2e-08.
