We look at the division of 51533773 by 139 
We want to figure out the number of times 51533773 can be divided by 139.

Going ahead to step 1:
The number 139 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 139

On to step 2:
139 goes into 51 0 times with a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Fetch the next digit (5) from the dividend, attach it to 51 and continue: 515 / 139

Let's proceed to step 3:
If we divide 515 by 139, we get 3 and a remainder of 98.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 417 from 515, we get 98.
Bring next digit (3) of the dividend behind the 98 and repeat the process: 983 / 139

Step 4:
983 divided by 139 is 7 with a remainder of 10.
The next digit of our result is 7. 
Result so far: 37.0
If we subtract 973 from 983, we get 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 139

Going ahead to step 5:
139 can be fit into 103 0 times, resulting in a remainder of 103.
Write down 0 as next digit of the result. 
Result so far: 370.0
Subtracting 0 from 103 leaves us with 103.
Include the next digit (7) from the dividend after 103, then repeat: 1037 / 139

Moving on to step 6:
If we divide 1037 by 139, we get 7 and a remainder of 64.
Record the quotient 7 as the next digit in the result. 
Result so far: 3707.0
If we take 973 away from 1037, we end up with 64.
Bring next digit (7) of the dividend behind the 64 and repeat the process: 647 / 139

Moving on to step 7:
If we divide 647 by 139, we get 4 and a remainder of 91.
Record the quotient 4 as the next digit in the result. 
Result so far: 37074.0
Deduct 556 from 647 and we're left with 91.
Bring next digit (3) of the dividend behind the 91 and repeat the process: 913 / 139

Let's proceed to step 8:
If we divide 913 by 139, we get 6 and a remainder of 79.
Write down 6 as next digit of the result. 
Result so far: 370746.0
Subtract 834 from 913 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 9:
If we divide 790 by 139, we get 5 and a remainder of 95.
Use 5 as the next digit of our solution. 
Result so far: 370746.5
Deduct 695 from 790 and we're left with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Moving on to step 10:
139 goes into 950 6 times with a remainder of 116.
Put 6 as the next digit of the answer. 
Result so far: 370746.56
If we subtract 834 from 950, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 11:
If we divide 1160 by 139, we get 8 and a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 370746.568
If we subtract 1112 from 1160, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 12:
139 goes into 480 3 times with a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 370746.5683
Subtract 417 from 480 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 13:
If we divide 630 by 139, we get 4 and a remainder of 74.
Use 4 as the next digit of our solution. 
Result so far: 370746.56834
If we take 556 away from 630, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 14:
740 divided by 139 is 5 with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 370746.568345
If we take 695 away from 740, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 15:
139 goes into 450 3 times with a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 370746.5683453
Subtracting 417 from 450 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 16:
If we divide 330 by 139, we get 2 and a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 370746.56834532
Subtract 278 from 330 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Our division results in 370746.56834532 with a remaining 5.2e-08.
