96859866 divided by 49 
We want to figure out the number of times 96859866 can be divided by 49.

On to step 1:
If we divide 9 by 49, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 49

Moving on to step 2:
49 can be fit into 96 1 times, resulting in a remainder of 47.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 49 from 96 to get 47.
Bring next digit (8) of the dividend behind the 47 and repeat the process: 478 / 49

On to step 3:
The number 49 fits into 478 9 times, leaving a remainder of 37.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Deduct 441 from 478 and we're left with 37.
Bring next digit (5) of the dividend behind the 37 and repeat the process: 375 / 49

On to step 4:
375 divided by 49 is 7 with a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 197.0
If we take 343 away from 375, we end up with 32.
Append the next digit (9) from the dividend to 32 and continue with: 329 / 49

Advancing to step 5:
When dividing 329 by 49, we get 6 with a remainder of 35.
Put 6 as the next digit of the answer. 
Result so far: 1976.0
If we subtract 294 from 329, we get 35.
Take the next digit (8) from the dividend and append it to 35, then repeat: 358 / 49

Step 6:
49 goes into 358 7 times with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 19767.0
Subtract 343 from 358 to get 15.
Bring next digit (6) of the dividend behind the 15 and repeat the process: 156 / 49

Step 7:
49 goes into 156 3 times with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 197673.0
Subtracting 147 from 156 leaves us with 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 49

Step 8:
49 can be fit into 96 1 times, resulting in a remainder of 47.
Write down 1 as next digit of the result. 
Result so far: 1976731.0
If we take 49 away from 96, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 9:
The number 49 fits into 470 9 times, leaving a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 1976731.9
The remainder is 29 after subtracting 441 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 10:
The number 49 fits into 290 5 times, leaving a remainder of 45.
The next digit of our result is 5. 
Result so far: 1976731.95
Deduct 245 from 290 and we're left 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.

Let's proceed to step 11:
The number 49 fits into 450 9 times, leaving a remainder of 9.
The next digit of our result is 9. 
Result so far: 1976731.959
The remainder is 9 after subtracting 441 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 12:
When dividing 90 by 49, we get 1 with a remainder of 41.
Write down 1 as next digit of the result. 
Result so far: 1976731.9591
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.

Moving on to step 13:
410 divided by 49 is 8 with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 1976731.95918
Subtracting 392 from 410 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 14:
49 can be fit into 180 3 times, resulting in a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 1976731.959183
Subtract 147 from 180 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 15:
If we divide 330 by 49, we get 6 and a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 1976731.9591836
If we take 294 away from 330, we end up 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.

Moving on to step 16:
49 can be fit into 360 7 times, resulting in a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 1976731.95918367
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.

The final outcome is 1976731.95918367, with a leftover of 1.7e-08.
