49920109 ÷ 371 
Our goal is to divide 49920109 by 371.

Step 1:
4 divided by 371 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 371

Step 2:
When dividing 49 by 371, we get 0 with a remainder of 49.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 49 to get 49.
Take the next digit (9) from the dividend and append it to 49, then repeat: 499 / 371

Advancing to step 3:
When dividing 499 by 371, we get 1 with a remainder of 128.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 371 from 499 and we're left with 128.
Fetch the next digit (2) from the dividend, attach it to 128 and continue: 1282 / 371

On to step 4:
When dividing 1282 by 371, we get 3 with a remainder of 169.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we take 1113 away from 1282, we end up with 169.
Bring next digit (0) of the dividend behind the 169 and repeat the process: 1690 / 371

Moving on to step 5:
If we divide 1690 by 371, we get 4 and a remainder of 206.
The next digit of our result is 4. 
Result so far: 134.0
If we take 1484 away from 1690, we end up with 206.
Take the next digit (1) from the dividend and append it to 206, then repeat: 2061 / 371

Let's proceed to step 6:
371 goes into 2061 5 times with a remainder of 206.
The next digit of our result is 5. 
Result so far: 1345.0
Deduct 1855 from 2061 and we're left with 206.
Append the next digit (0) from the dividend to 206 and continue with: 2060 / 371

Let's proceed to step 7:
371 goes into 2060 5 times with a remainder of 205.
The next digit of our result is 5. 
Result so far: 13455.0
Subtracting 1855 from 2060 leaves us with 205.
Take the next digit (9) from the dividend and append it to 205, then repeat: 2059 / 371

Let's proceed to step 8:
If we divide 2059 by 371, we get 5 and a remainder of 204.
The next digit of our result is 5. 
Result so far: 134555.0
Deduct 1855 from 2059 and we're left with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Step 9:
2040 divided by 371 is 5 with a remainder of 185.
The number 5 becomes the next digit in our result. 
Result so far: 134555.5
The remainder is 185 after subtracting 1855 from 2040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Let's proceed to step 10:
When dividing 1850 by 371, we get 4 with a remainder of 366.
The next digit of our result is 4. 
Result so far: 134555.54
Subtracting 1484 from 1850 leaves us with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

On to step 11:
The number 371 fits into 3660 9 times, leaving a remainder of 321.
Write down 9 as next digit of the result. 
Result so far: 134555.549
Subtracting 3339 from 3660 leaves us with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Let's proceed to step 12:
If we divide 3210 by 371, we get 8 and a remainder of 242.
The next digit of our result is 8. 
Result so far: 134555.5498
If we subtract 2968 from 3210, we get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Advancing to step 13:
371 goes into 2420 6 times with a remainder of 194.
The next digit of our result is 6. 
Result so far: 134555.54986
If we take 2226 away from 2420, we end up with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Going ahead to step 14:
When dividing 1940 by 371, we get 5 with a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 134555.549865
Deduct 1855 from 1940 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 15:
371 can be fit into 850 2 times, resulting in a remainder of 108.
Put 2 as the next digit of the answer. 
Result so far: 134555.5498652
Deduct 742 from 850 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 16:
371 can be fit into 1080 2 times, resulting in a remainder of 338.
Use 2 as the next digit of our solution. 
Result so far: 134555.54986522
If we take 742 away from 1080, we end up with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

The final result is 134555.54986522 with a remainder of 3.38e-07.
