37872103 divided by 51 
Our goal is to divide 37872103 by 51.

Advancing to step 1:
When dividing 3 by 51, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 51

Let's proceed to step 2:
51 goes into 37 0 times with a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 37, we end up with 37.
Take the next digit (8) from the dividend and append it to 37, then repeat: 378 / 51

Advancing to step 3:
51 can be fit into 378 7 times, resulting in a remainder of 21.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 357 from 378 leaves us with 21.
Append the next digit (7) from the dividend to 21 and continue with: 217 / 51

Going ahead to step 4:
If we divide 217 by 51, we get 4 and a remainder of 13.
Write down 4 as next digit of the result. 
Result so far: 74.0
Subtracting 204 from 217 leaves us with 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 51

Going ahead to step 5:
If we divide 132 by 51, we get 2 and a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 742.0
Subtract 102 from 132 to get 30.
Take the next digit (1) from the dividend and append it to 30, then repeat: 301 / 51

Moving on to step 6:
When dividing 301 by 51, we get 5 with a remainder of 46.
Record the quotient 5 as the next digit in the result. 
Result so far: 7425.0
The remainder is 46 after subtracting 255 from 301.
Take the next digit (0) from the dividend and append it to 46, then repeat: 460 / 51

Going ahead to step 7:
The number 51 fits into 460 9 times, leaving a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 74259.0
Deduct 459 from 460 and we're left with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 51

Going ahead to step 8:
51 goes into 13 0 times with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 742590.0
If we take 0 away from 13, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 9:
51 can be fit into 130 2 times, resulting in a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 742590.2
Deduct 102 from 130 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 10:
If we divide 280 by 51, we get 5 and a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 742590.25
If we take 255 away from 280, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 11:
51 can be fit into 250 4 times, resulting in a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 742590.254
Subtract 204 from 250 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 12:
51 can be fit into 460 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 742590.2549
The remainder is 1 after subtracting 459 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 13:
The number 51 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 742590.2549
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
100 divided by 51 is 1 with a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 742590.254901
The remainder is 49 after subtracting 51 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 15:
If we divide 490 by 51, we get 9 and a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 742590.2549019
Subtract 459 from 490 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 16:
51 can be fit into 310 6 times, resulting in a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 742590.25490196
If we take 306 away from 310, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 742590.25490196 with a remaining 4e-09.
