We look at the division of 51961551 by 377 
Let's see how many times 377 fits into 51961551.

Moving on to step 1:
5 divided by 377 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 377

Step 2:
377 goes into 51 0 times with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Bring next digit (9) of the dividend behind the 51 and repeat the process: 519 / 377

Advancing to step 3:
377 goes into 519 1 times with a remainder of 142.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 377 from 519 to get 142.
Append the next digit (6) from the dividend to 142 and continue with: 1426 / 377

Let's proceed to step 4:
When dividing 1426 by 377, we get 3 with a remainder of 295.
Write down 3 as next digit of the result. 
Result so far: 13.0
Deduct 1131 from 1426 and we're left with 295.
Bring next digit (1) of the dividend behind the 295 and repeat the process: 2951 / 377

Advancing to step 5:
377 can be fit into 2951 7 times, resulting in a remainder of 312.
The next digit of our result is 7. 
Result so far: 137.0
If we take 2639 away from 2951, we end up with 312.
Include the next digit (5) from the dividend after 312, then repeat: 3125 / 377

Moving on to step 6:
If we divide 3125 by 377, we get 8 and a remainder of 109.
The next digit of our result is 8. 
Result so far: 1378.0
If we take 3016 away from 3125, we end up with 109.
Take the next digit (5) from the dividend and append it to 109, then repeat: 1095 / 377

Step 7:
377 goes into 1095 2 times with a remainder of 341.
Put 2 as the next digit of the answer. 
Result so far: 13782.0
Subtract 754 from 1095 to get 341.
Bring next digit (1) of the dividend behind the 341 and repeat the process: 3411 / 377

Let's proceed to step 8:
377 can be fit into 3411 9 times, resulting in a remainder of 18.
The next digit of our result is 9. 
Result so far: 137829.0
Subtract 3393 from 3411 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 9:
180 divided by 377 is 0 with a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 137829.0
Subtract 0 from 180 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 10:
377 goes into 1800 4 times with a remainder of 292.
Use 4 as the next digit of our solution. 
Result so far: 137829.04
Deduct 1508 from 1800 and we're left with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Going ahead to step 11:
The number 377 fits into 2920 7 times, leaving a remainder of 281.
The number 7 becomes the next digit in our result. 
Result so far: 137829.047
Subtracting 2639 from 2920 leaves us with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Moving on to step 12:
When dividing 2810 by 377, we get 7 with a remainder of 171.
Use 7 as the next digit of our solution. 
Result so far: 137829.0477
Deduct 2639 from 2810 and we're left with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Our division results in 137829.0477 with a remaining 0.00171.
