We look at the division of 43730173 by 691 
We're looking to find how many times 691 goes into 43730173.

Step 1:
691 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 691

Moving on to step 2:
When dividing 43 by 691, we get 0 with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Fetch the next digit (7) from the dividend, attach it to 43 and continue: 437 / 691

Going ahead to step 3:
If we divide 437 by 691, we get 0 and a remainder of 437.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 437 leaves us with 437.
Bring next digit (3) of the dividend behind the 437 and repeat the process: 4373 / 691

Let's proceed to step 4:
When dividing 4373 by 691, we get 6 with a remainder of 227.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 227 after subtracting 4146 from 4373.
Append the next digit (0) from the dividend to 227 and continue with: 2270 / 691

Let's proceed to step 5:
2270 divided by 691 is 3 with a remainder of 197.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
If we take 2073 away from 2270, we end up with 197.
Bring next digit (1) of the dividend behind the 197 and repeat the process: 1971 / 691

Going ahead to step 6:
691 goes into 1971 2 times with a remainder of 589.
Put 2 as the next digit of the answer. 
Result so far: 632.0
Deduct 1382 from 1971 and we're left with 589.
Include the next digit (7) from the dividend after 589, then repeat: 5897 / 691

On to step 7:
5897 divided by 691 is 8 with a remainder of 369.
Record the quotient 8 as the next digit in the result. 
Result so far: 6328.0
Subtract 5528 from 5897 to get 369.
Include the next digit (3) from the dividend after 369, then repeat: 3693 / 691

On to step 8:
The number 691 fits into 3693 5 times, leaving a remainder of 238.
Record the quotient 5 as the next digit in the result. 
Result so far: 63285.0
Subtract 3455 from 3693 to get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Going ahead to step 9:
2380 divided by 691 is 3 with a remainder of 307.
Write down 3 as next digit of the result. 
Result so far: 63285.3
If we subtract 2073 from 2380, we get 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Step 10:
If we divide 3070 by 691, we get 4 and a remainder of 306.
Put 4 as the next digit of the answer. 
Result so far: 63285.34
Subtracting 2764 from 3070 leaves us with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Let's proceed to step 11:
When dividing 3060 by 691, we get 4 with a remainder of 296.
Write down 4 as next digit of the result. 
Result so far: 63285.344
Subtract 2764 from 3060 to get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

The final outcome is 63285.344, with a leftover of 0.0296.
