We look at the division of 37577820 by 307 
Let's see how many times 307 fits into 37577820.

Step 1:
If we divide 3 by 307, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 307

Step 2:
37 divided by 307 is 0 with a remainder of 37.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 37 after subtracting 0 from 37.
Bring next digit (5) of the dividend behind the 37 and repeat the process: 375 / 307

Advancing to step 3:
If we divide 375 by 307, we get 1 and a remainder of 68.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 307 from 375, we get 68.
Fetch the next digit (7) from the dividend, attach it to 68 and continue: 687 / 307

Advancing to step 4:
307 goes into 687 2 times with a remainder of 73.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 614 from 687 and we're left with 73.
Bring next digit (7) of the dividend behind the 73 and repeat the process: 737 / 307

Step 5:
307 goes into 737 2 times with a remainder of 123.
Record the quotient 2 as the next digit in the result. 
Result so far: 122.0
If we subtract 614 from 737, we get 123.
Bring next digit (8) of the dividend behind the 123 and repeat the process: 1238 / 307

Moving on to step 6:
307 can be fit into 1238 4 times, resulting in a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 1224.0
The remainder is 10 after subtracting 1228 from 1238.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 307

Moving on to step 7:
102 divided by 307 is 0 with a remainder of 102.
The number 0 becomes the next digit in our result. 
Result so far: 12240.0
If we take 0 away from 102, we end up with 102.
Append the next digit (0) from the dividend to 102 and continue with: 1020 / 307

Let's proceed to step 8:
307 goes into 1020 3 times with a remainder of 99.
The number 3 becomes the next digit in our result. 
Result so far: 122403.0
Subtracting 921 from 1020 leaves us with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Advancing to step 9:
307 can be fit into 990 3 times, resulting in a remainder of 69.
Put 3 as the next digit of the answer. 
Result so far: 122403.3
If we take 921 away from 990, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 10:
The number 307 fits into 690 2 times, leaving a remainder of 76.
Write down 2 as next digit of the result. 
Result so far: 122403.32
Deduct 614 from 690 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 11:
307 can be fit into 760 2 times, resulting in a remainder of 146.
Put 2 as the next digit of the answer. 
Result so far: 122403.322
If we subtract 614 from 760, we get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

The final outcome is 122403.322, with a leftover of 0.0146.
