We divide 48215897 by 661
We want to divide 48215897 by 661.

Let's proceed to step 1:
661 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 661

Going ahead to step 2:
48 divided by 661 is 0 with a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 48 to get 48.
Append the next digit (2) from the dividend to 48 and continue with: 482 / 661

Step 3:
If we divide 482 by 661, we get 0 and a remainder of 482.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 482 after subtracting 0 from 482.
Fetch the next digit (1) from the dividend, attach it to 482 and continue: 4821 / 661

Let's proceed to step 4:
If we divide 4821 by 661, we get 7 and a remainder of 194.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 4627 from 4821 to get 194.
Append the next digit (5) from the dividend to 194 and continue with: 1945 / 661

Step 5:
The number 661 fits into 1945 2 times, leaving a remainder of 623.
Write down 2 as next digit of the result. 
Result so far: 72.0
If we take 1322 away from 1945, we end up with 623.
Append the next digit (8) from the dividend to 623 and continue with: 6238 / 661

Going ahead to step 6:
6238 divided by 661 is 9 with a remainder of 289.
The number 9 becomes the next digit in our result. 
Result so far: 729.0
If we take 5949 away from 6238, we end up with 289.
Take the next digit (9) from the dividend and append it to 289, then repeat: 2899 / 661

Going ahead to step 7:
661 goes into 2899 4 times with a remainder of 255.
The next digit of our result is 4. 
Result so far: 7294.0
Deduct 2644 from 2899 and we're left with 255.
Take the next digit (7) from the dividend and append it to 255, then repeat: 2557 / 661

Advancing to step 8:
661 can be fit into 2557 3 times, resulting in a remainder of 574.
The next digit of our result is 3. 
Result so far: 72943.0
Subtract 1983 from 2557 to get 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Advancing to step 9:
The number 661 fits into 5740 8 times, leaving a remainder of 452.
The number 8 becomes the next digit in our result. 
Result so far: 72943.8
The remainder is 452 after subtracting 5288 from 5740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

On to step 10:
661 goes into 4520 6 times with a remainder of 554.
Write down 6 as next digit of the result. 
Result so far: 72943.86
If we take 3966 away from 4520, we end up with 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Step 11:
661 goes into 5540 8 times with a remainder of 252.
Use 8 as the next digit of our solution. 
Result so far: 72943.868
Subtract 5288 from 5540 to get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Moving on to step 12:
661 goes into 2520 3 times with a remainder of 537.
Put 3 as the next digit of the answer. 
Result so far: 72943.8683
Deduct 1983 from 2520 and we're left with 537.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5370, and continue the process.

On to step 13:
When dividing 5370 by 661, we get 8 with a remainder of 82.
The next digit of our result is 8. 
Result so far: 72943.86838
Subtract 5288 from 5370 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 14:
When dividing 820 by 661, we get 1 with a remainder of 159.
Put 1 as the next digit of the answer. 
Result so far: 72943.868381
If we take 661 away from 820, we end up with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Advancing to step 15:
661 goes into 1590 2 times with a remainder of 268.
Use 2 as the next digit of our solution. 
Result so far: 72943.8683812
If we take 1322 away from 1590, we end up with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Moving on to step 16:
661 goes into 2680 4 times with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 72943.86838124
Subtract 2644 from 2680 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 72943.86838124, with a leftover of 3.6e-08.
