90646339 divided by 49 
We want to figure out the number of times 90646339 can be divided by 49.

Going ahead to step 1:
If we divide 9 by 49, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 49

Moving on to step 2:
The number 49 fits into 90 1 times, leaving a remainder of 41.
The next digit of our result is 1. 
Result so far: 1.0
If we take 49 away from 90, we end up with 41.
Grab the next digit (6) from the dividend, add it to 41, then carry on: 416 / 49

Going ahead to step 3:
49 can be fit into 416 8 times, resulting in a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtracting 392 from 416 leaves us with 24.
Grab the next digit (4) from the dividend, add it to 24, then carry on: 244 / 49

Step 4:
When dividing 244 by 49, we get 4 with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 184.0
If we subtract 196 from 244, we get 48.
Grab the next digit (6) from the dividend, add it to 48, then carry on: 486 / 49

Step 5:
49 goes into 486 9 times with a remainder of 45.
Put 9 as the next digit of the answer. 
Result so far: 1849.0
If we subtract 441 from 486, we get 45.
Append the next digit (3) from the dividend to 45 and continue with: 453 / 49

Advancing to step 6:
49 goes into 453 9 times with a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 18499.0
The remainder is 12 after subtracting 441 from 453.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 49

Step 7:
49 can be fit into 123 2 times, resulting in a remainder of 25.
Write down 2 as next digit of the result. 
Result so far: 184992.0
Subtracting 98 from 123 leaves us with 25.
Fetch the next digit (9) from the dividend, attach it to 25 and continue: 259 / 49

Advancing to step 8:
49 can be fit into 259 5 times, resulting in a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 1849925.0
Subtract 245 from 259 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 9:
49 goes into 140 2 times with a remainder of 42.
Use 2 as the next digit of our solution. 
Result so far: 1849925.2
The remainder is 42 after subtracting 98 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 10:
If we divide 420 by 49, we get 8 and a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 1849925.28
The remainder is 28 after subtracting 392 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 11:
49 goes into 280 5 times with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 1849925.285
Subtract 245 from 280 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 12:
49 goes into 350 7 times with a remainder of 7.
The next digit of our result is 7. 
Result so far: 1849925.2857
If we subtract 343 from 350, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 13:
70 divided by 49 is 1 with a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 1849925.28571
The remainder is 21 after subtracting 49 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 14:
If we divide 210 by 49, we get 4 and a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 1849925.285714
If we subtract 196 from 210, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 15:
140 divided by 49 is 2 with a remainder of 42.
The next digit of our result is 2. 
Result so far: 1849925.2857142
Subtract 98 from 140 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 16:
If we divide 420 by 49, we get 8 and a remainder of 28.
The next digit of our result is 8. 
Result so far: 1849925.28571428
Deduct 392 from 420 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.

In conclusion, the division gives 1849925.28571428 with a balance of 2.8e-08.
