64221409 divided by 357 
We want to figure out the number of times 64221409 can be divided by 357.

Going ahead to step 1:
If we divide 6 by 357, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 357

Step 2:
The number 357 fits into 64 0 times, leaving a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Append the next digit (2) from the dividend to 64 and continue with: 642 / 357

Let's proceed to step 3:
357 can be fit into 642 1 times, resulting in a remainder of 285.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 357 from 642 and we're left with 285.
Grab the next digit (2) from the dividend, add it to 285, then carry on: 2852 / 357

Going ahead to step 4:
When dividing 2852 by 357, we get 7 with a remainder of 353.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we subtract 2499 from 2852, we get 353.
Grab the next digit (1) from the dividend, add it to 353, then carry on: 3531 / 357

Step 5:
When dividing 3531 by 357, we get 9 with a remainder of 318.
Use 9 as the next digit of our solution. 
Result so far: 179.0
If we subtract 3213 from 3531, we get 318.
Grab the next digit (4) from the dividend, add it to 318, then carry on: 3184 / 357

Moving on to step 6:
3184 divided by 357 is 8 with a remainder of 328.
Put 8 as the next digit of the answer. 
Result so far: 1798.0
Subtracting 2856 from 3184 leaves us with 328.
Grab the next digit (0) from the dividend, add it to 328, then carry on: 3280 / 357

Advancing to step 7:
The number 357 fits into 3280 9 times, leaving a remainder of 67.
Put 9 as the next digit of the answer. 
Result so far: 17989.0
If we subtract 3213 from 3280, we get 67.
Include the next digit (9) from the dividend after 67, then repeat: 679 / 357

Going ahead to step 8:
If we divide 679 by 357, we get 1 and a remainder of 322.
Record the quotient 1 as the next digit in the result. 
Result so far: 179891.0
Subtract 357 from 679 to get 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Going ahead to step 9:
357 can be fit into 3220 9 times, resulting in a remainder of 7.
The next digit of our result is 9. 
Result so far: 179891.9
The remainder is 7 after subtracting 3213 from 3220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 10:
If we divide 70 by 357, we get 0 and a remainder of 70.
The next digit of our result is 0. 
Result so far: 179891.9
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 11:
If we divide 700 by 357, we get 1 and a remainder of 343.
Record the quotient 1 as the next digit in the result. 
Result so far: 179891.901
Deduct 357 from 700 and we're left with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

On to step 12:
357 can be fit into 3430 9 times, resulting in a remainder of 217.
The next digit of our result is 9. 
Result so far: 179891.9019
The remainder is 217 after subtracting 3213 from 3430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Advancing to step 13:
357 can be fit into 2170 6 times, resulting in a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 179891.90196
Subtract 2142 from 2170 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 14:
357 goes into 280 0 times with a remainder of 280.
Use 0 as the next digit of our solution. 
Result so far: 179891.90196
Subtracting 0 from 280 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 15:
357 goes into 2800 7 times with a remainder of 301.
The number 7 becomes the next digit in our result. 
Result so far: 179891.9019607
The remainder is 301 after subtracting 2499 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Let's proceed to step 16:
If we divide 3010 by 357, we get 8 and a remainder of 154.
Put 8 as the next digit of the answer. 
Result so far: 179891.90196078
Subtracting 2856 from 3010 leaves us with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

After the division, we end up with 179891.90196078 and a remainder of 1.54e-07.
