We're dividing 51690521 by 49 
We're looking to find how many times 49 goes into 51690521.

On to step 1:
If we divide 5 by 49, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 49

Going ahead to step 2:
49 goes into 51 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 49 from 51 leaves us with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 49

Advancing to step 3:
When dividing 26 by 49, we get 0 with a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 26, we get 26.
Fetch the next digit (9) from the dividend, attach it to 26 and continue: 269 / 49

Let's proceed to step 4:
269 divided by 49 is 5 with a remainder of 24.
Use 5 as the next digit of our solution. 
Result so far: 105.0
If we take 245 away from 269, we end up with 24.
Bring next digit (0) of the dividend behind the 24 and repeat the process: 240 / 49

On to step 5:
49 can be fit into 240 4 times, resulting in a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 1054.0
If we subtract 196 from 240, we get 44.
Fetch the next digit (5) from the dividend, attach it to 44 and continue: 445 / 49

Step 6:
49 can be fit into 445 9 times, resulting in a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 10549.0
Subtracting 441 from 445 leaves us with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 49

Moving on to step 7:
42 divided by 49 is 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 105490.0
Deduct 0 from 42 and we're left with 42.
Append the next digit (1) from the dividend to 42 and continue with: 421 / 49

On to step 8:
When dividing 421 by 49, we get 8 with a remainder of 29.
Put 8 as the next digit of the answer. 
Result so far: 1054908.0
If we take 392 away from 421, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 9:
290 divided by 49 is 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 1054908.5
If we take 245 away from 290, 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.

Going ahead to step 10:
The number 49 fits into 450 9 times, leaving a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 1054908.59
If we subtract 441 from 450, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 11:
49 can be fit into 90 1 times, resulting in a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 1054908.591
Subtracting 49 from 90 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 12:
49 can be fit into 410 8 times, resulting in a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 1054908.5918
If we subtract 392 from 410, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 13:
When dividing 180 by 49, we get 3 with a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 1054908.59183
The remainder is 33 after subtracting 147 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 14:
49 goes into 330 6 times with a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 1054908.591836
Subtracting 294 from 330 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 15:
49 can be fit into 360 7 times, resulting in a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 1054908.5918367
Subtracting 343 from 360 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 16:
The number 49 fits into 170 3 times, leaving a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 1054908.59183673
The remainder is 23 after subtracting 147 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final outcome is 1054908.59183673, with a leftover of 2.3e-08.
