We look at the division of 73690330 by 426 
We're looking to find how many times 426 goes into 73690330.

On to step 1:
If we divide 7 by 426, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 426

Step 2:
When dividing 73 by 426, we get 0 with a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Grab the next digit (6) from the dividend, add it to 73, then carry on: 736 / 426

Let's proceed to step 3:
426 goes into 736 1 times with a remainder of 310.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 426 away from 736, we end up with 310.
Include the next digit (9) from the dividend after 310, then repeat: 3109 / 426

Step 4:
The number 426 fits into 3109 7 times, leaving a remainder of 127.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtract 2982 from 3109 to get 127.
Bring next digit (0) of the dividend behind the 127 and repeat the process: 1270 / 426

On to step 5:
426 goes into 1270 2 times with a remainder of 418.
The next digit of our result is 2. 
Result so far: 172.0
Subtracting 852 from 1270 leaves us with 418.
Append the next digit (3) from the dividend to 418 and continue with: 4183 / 426

Going ahead to step 6:
426 can be fit into 4183 9 times, resulting in a remainder of 349.
Record the quotient 9 as the next digit in the result. 
Result so far: 1729.0
Subtracting 3834 from 4183 leaves us with 349.
Take the next digit (3) from the dividend and append it to 349, then repeat: 3493 / 426

Let's proceed to step 7:
The number 426 fits into 3493 8 times, leaving a remainder of 85.
Use 8 as the next digit of our solution. 
Result so far: 17298.0
The remainder is 85 after subtracting 3408 from 3493.
Grab the next digit (0) from the dividend, add it to 85, then carry on: 850 / 426

On to step 8:
When dividing 850 by 426, we get 1 with a remainder of 424.
Use 1 as the next digit of our solution. 
Result so far: 172981.0
Deduct 426 from 850 and we're left with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Advancing to step 9:
When dividing 4240 by 426, we get 9 with a remainder of 406.
Write down 9 as next digit of the result. 
Result so far: 172981.9
The remainder is 406 after subtracting 3834 from 4240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Advancing to step 10:
When dividing 4060 by 426, we get 9 with a remainder of 226.
Write down 9 as next digit of the result. 
Result so far: 172981.99
If we take 3834 away from 4060, we end up with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

The final outcome is 172981.99, with a leftover of 0.226.
