We look at the division of 51559474 by 371 
We want to divide 51559474 by 371.

Advancing to step 1:
5 divided by 371 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 371

Step 2:
The number 371 fits into 51 0 times, leaving a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Append the next digit (5) from the dividend to 51 and continue with: 515 / 371

Let's proceed to step 3:
When dividing 515 by 371, we get 1 with a remainder of 144.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 371 from 515, we get 144.
Include the next digit (5) from the dividend after 144, then repeat: 1445 / 371

Let's proceed to step 4:
If we divide 1445 by 371, we get 3 and a remainder of 332.
The next digit of our result is 3. 
Result so far: 13.0
If we take 1113 away from 1445, we end up with 332.
Include the next digit (9) from the dividend after 332, then repeat: 3329 / 371

Going ahead to step 5:
The number 371 fits into 3329 8 times, leaving a remainder of 361.
The next digit of our result is 8. 
Result so far: 138.0
Subtract 2968 from 3329 to get 361.
Grab the next digit (4) from the dividend, add it to 361, then carry on: 3614 / 371

Step 6:
When dividing 3614 by 371, we get 9 with a remainder of 275.
Write down 9 as next digit of the result. 
Result so far: 1389.0
If we subtract 3339 from 3614, we get 275.
Bring next digit (7) of the dividend behind the 275 and repeat the process: 2757 / 371

Let's proceed to step 7:
The number 371 fits into 2757 7 times, leaving a remainder of 160.
The next digit of our result is 7. 
Result so far: 13897.0
If we subtract 2597 from 2757, we get 160.
Bring next digit (4) of the dividend behind the 160 and repeat the process: 1604 / 371

Advancing to step 8:
The number 371 fits into 1604 4 times, leaving a remainder of 120.
Record the quotient 4 as the next digit in the result. 
Result so far: 138974.0
Subtract 1484 from 1604 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 9:
371 goes into 1200 3 times with a remainder of 87.
Put 3 as the next digit of the answer. 
Result so far: 138974.3
Deduct 1113 from 1200 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 10:
371 can be fit into 870 2 times, resulting in a remainder of 128.
Record the quotient 2 as the next digit in the result. 
Result so far: 138974.32
If we take 742 away from 870, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 11:
If we divide 1280 by 371, we get 3 and a remainder of 167.
Use 3 as the next digit of our solution. 
Result so far: 138974.323
If we subtract 1113 from 1280, we get 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Going ahead to step 12:
1670 divided by 371 is 4 with a remainder of 186.
Record the quotient 4 as the next digit in the result. 
Result so far: 138974.3234
Subtracting 1484 from 1670 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 13:
371 goes into 1860 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 138974.32345
Subtracting 1855 from 1860 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 14:
50 divided by 371 is 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 138974.32345
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 15:
When dividing 500 by 371, we get 1 with a remainder of 129.
The number 1 becomes the next digit in our result. 
Result so far: 138974.3234501
Subtract 371 from 500 to get 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Going ahead to step 16:
371 goes into 1290 3 times with a remainder of 177.
The number 3 becomes the next digit in our result. 
Result so far: 138974.32345013
If we subtract 1113 from 1290, we get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

In conclusion, the division gives 138974.32345013 with a balance of 1.77e-07.
