We look at the division of 51987604 by 379 
Let's see how many times 379 fits into 51987604.

Advancing to step 1:
379 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 379

Let's proceed to step 2:
When dividing 51 by 379, we get 0 with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Append the next digit (9) from the dividend to 51 and continue with: 519 / 379

Moving on to step 3:
When dividing 519 by 379, we get 1 with a remainder of 140.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 379 from 519, we get 140.
Grab the next digit (8) from the dividend, add it to 140, then carry on: 1408 / 379

On to step 4:
379 goes into 1408 3 times with a remainder of 271.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 1137 from 1408 and we're left with 271.
Bring next digit (7) of the dividend behind the 271 and repeat the process: 2717 / 379

Advancing to step 5:
2717 divided by 379 is 7 with a remainder of 64.
The number 7 becomes the next digit in our result. 
Result so far: 137.0
Subtract 2653 from 2717 to get 64.
Include the next digit (6) from the dividend after 64, then repeat: 646 / 379

Going ahead to step 6:
379 goes into 646 1 times with a remainder of 267.
The number 1 becomes the next digit in our result. 
Result so far: 1371.0
Subtract 379 from 646 to get 267.
Fetch the next digit (0) from the dividend, attach it to 267 and continue: 2670 / 379

Step 7:
2670 divided by 379 is 7 with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 13717.0
Subtract 2653 from 2670 to get 17.
Grab the next digit (4) from the dividend, add it to 17, then carry on: 174 / 379

Advancing to step 8:
379 goes into 174 0 times with a remainder of 174.
The next digit of our result is 0. 
Result so far: 137170.0
Subtracting 0 from 174 leaves us with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Step 9:
1740 divided by 379 is 4 with a remainder of 224.
The number 4 becomes the next digit in our result. 
Result so far: 137170.4
Deduct 1516 from 1740 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 10:
379 goes into 2240 5 times with a remainder of 345.
The number 5 becomes the next digit in our result. 
Result so far: 137170.45
If we subtract 1895 from 2240, we get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

On to step 11:
If we divide 3450 by 379, we get 9 and a remainder of 39.
Record the quotient 9 as the next digit in the result. 
Result so far: 137170.459
The remainder is 39 after subtracting 3411 from 3450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 12:
379 goes into 390 1 times with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 137170.4591
If we take 379 away from 390, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 13:
379 can be fit into 110 0 times, resulting in a remainder of 110.
Put 0 as the next digit of the answer. 
Result so far: 137170.4591
Subtract 0 from 110 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 14:
379 can be fit into 1100 2 times, resulting in a remainder of 342.
Put 2 as the next digit of the answer. 
Result so far: 137170.459102
The remainder is 342 after subtracting 758 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Step 15:
3420 divided by 379 is 9 with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 137170.4591029
If we take 3411 away from 3420, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 16:
The number 379 fits into 90 0 times, leaving a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 137170.4591029
If we take 0 away from 90, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

The final outcome is 137170.4591029, with a leftover of 9e-08.
