73670147 ÷ 357 
Our goal is to divide 73670147 by 357.

Step 1:
7 divided by 357 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 357

Going ahead to step 2:
When dividing 73 by 357, we get 0 with a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 73, we end up with 73.
Take the next digit (6) from the dividend and append it to 73, then repeat: 736 / 357

Step 3:
The number 357 fits into 736 2 times, leaving a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 22 after subtracting 714 from 736.
Take the next digit (7) from the dividend and append it to 22, then repeat: 227 / 357

Advancing to step 4:
When dividing 227 by 357, we get 0 with a remainder of 227.
The next digit of our result is 0. 
Result so far: 20.0
If we take 0 away from 227, we end up with 227.
Append the next digit (0) from the dividend to 227 and continue with: 2270 / 357

On to step 5:
357 can be fit into 2270 6 times, resulting in a remainder of 128.
Write down 6 as next digit of the result. 
Result so far: 206.0
Subtracting 2142 from 2270 leaves us with 128.
Fetch the next digit (1) from the dividend, attach it to 128 and continue: 1281 / 357

On to step 6:
When dividing 1281 by 357, we get 3 with a remainder of 210.
The next digit of our result is 3. 
Result so far: 2063.0
The remainder is 210 after subtracting 1071 from 1281.
Append the next digit (4) from the dividend to 210 and continue with: 2104 / 357

Going ahead to step 7:
357 goes into 2104 5 times with a remainder of 319.
Use 5 as the next digit of our solution. 
Result so far: 20635.0
Deduct 1785 from 2104 and we're left with 319.
Include the next digit (7) from the dividend after 319, then repeat: 3197 / 357

Going ahead to step 8:
3197 divided by 357 is 8 with a remainder of 341.
Put 8 as the next digit of the answer. 
Result so far: 206358.0
If we take 2856 away from 3197, we end up with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Moving on to step 9:
357 goes into 3410 9 times with a remainder of 197.
Record the quotient 9 as the next digit in the result. 
Result so far: 206358.9
Deduct 3213 from 3410 and we're left with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Going ahead to step 10:
The number 357 fits into 1970 5 times, leaving a remainder of 185.
Record the quotient 5 as the next digit in the result. 
Result so far: 206358.95
Subtract 1785 from 1970 to get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Going ahead to step 11:
357 goes into 1850 5 times with a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 206358.955
If we take 1785 away from 1850, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final outcome is 206358.955, with a leftover of 0.0065.
