51255583 ÷ 371 
We're looking to find how many times 371 goes into 51255583.

Moving on to step 1:
The number 371 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 371

Advancing to step 2:
51 divided by 371 is 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Append the next digit (2) from the dividend to 51 and continue with: 512 / 371

Moving on to step 3:
The number 371 fits into 512 1 times, leaving a remainder of 141.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 371 from 512 and we're left with 141.
Grab the next digit (5) from the dividend, add it to 141, then carry on: 1415 / 371

On to step 4:
371 goes into 1415 3 times with a remainder of 302.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtracting 1113 from 1415 leaves us with 302.
Append the next digit (5) from the dividend to 302 and continue with: 3025 / 371

Step 5:
The number 371 fits into 3025 8 times, leaving a remainder of 57.
Use 8 as the next digit of our solution. 
Result so far: 138.0
If we subtract 2968 from 3025, we get 57.
Grab the next digit (5) from the dividend, add it to 57, then carry on: 575 / 371

Let's proceed to step 6:
371 can be fit into 575 1 times, resulting in a remainder of 204.
The number 1 becomes the next digit in our result. 
Result so far: 1381.0
If we subtract 371 from 575, we get 204.
Append the next digit (8) from the dividend to 204 and continue with: 2048 / 371

On to step 7:
2048 divided by 371 is 5 with a remainder of 193.
The next digit of our result is 5. 
Result so far: 13815.0
Subtract 1855 from 2048 to get 193.
Take the next digit (3) from the dividend and append it to 193, then repeat: 1933 / 371

Advancing to step 8:
371 can be fit into 1933 5 times, resulting in a remainder of 78.
Record the quotient 5 as the next digit in the result. 
Result so far: 138155.0
Deduct 1855 from 1933 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 9:
If we divide 780 by 371, we get 2 and a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 138155.2
If we subtract 742 from 780, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 10:
371 can be fit into 380 1 times, resulting in a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 138155.21
The remainder is 9 after subtracting 371 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 11:
90 divided by 371 is 0 with a remainder of 90.
The next digit of our result is 0. 
Result so far: 138155.21
The remainder is 90 after subtracting 0 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 12:
371 goes into 900 2 times with a remainder of 158.
Write down 2 as next digit of the result. 
Result so far: 138155.2102
If we subtract 742 from 900, we get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Moving on to step 13:
371 goes into 1580 4 times with a remainder of 96.
Use 4 as the next digit of our solution. 
Result so far: 138155.21024
Deduct 1484 from 1580 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 14:
960 divided by 371 is 2 with a remainder of 218.
Write down 2 as next digit of the result. 
Result so far: 138155.210242
If we subtract 742 from 960, we get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Let's proceed to step 15:
If we divide 2180 by 371, we get 5 and a remainder of 325.
Record the quotient 5 as the next digit in the result. 
Result so far: 138155.2102425
If we subtract 1855 from 2180, we get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

On to step 16:
When dividing 3250 by 371, we get 8 with a remainder of 282.
The number 8 becomes the next digit in our result. 
Result so far: 138155.21024258
Subtracting 2968 from 3250 leaves us with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

In conclusion, the division gives 138155.21024258 with a balance of 2.82e-07.
