47485190 ÷ 121 
We want to figure out the number of times 47485190 can be divided by 121.

Step 1:
When dividing 4 by 121, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 121

Going ahead to step 2:
The number 121 fits into 47 0 times, leaving a remainder of 47.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 47 to get 47.
Fetch the next digit (4) from the dividend, attach it to 47 and continue: 474 / 121

Advancing to step 3:
474 divided by 121 is 3 with a remainder of 111.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 363 from 474 to get 111.
Fetch the next digit (8) from the dividend, attach it to 111 and continue: 1118 / 121

Going ahead to step 4:
121 can be fit into 1118 9 times, resulting in a remainder of 29.
The next digit of our result is 9. 
Result so far: 39.0
Subtract 1089 from 1118 to get 29.
Include the next digit (5) from the dividend after 29, then repeat: 295 / 121

On to step 5:
The number 121 fits into 295 2 times, leaving a remainder of 53.
Write down 2 as next digit of the result. 
Result so far: 392.0
Subtracting 242 from 295 leaves us with 53.
Append the next digit (1) from the dividend to 53 and continue with: 531 / 121

On to step 6:
531 divided by 121 is 4 with a remainder of 47.
The next digit of our result is 4. 
Result so far: 3924.0
If we take 484 away from 531, we end up with 47.
Grab the next digit (9) from the dividend, add it to 47, then carry on: 479 / 121

Going ahead to step 7:
479 divided by 121 is 3 with a remainder of 116.
The next digit of our result is 3. 
Result so far: 39243.0
If we subtract 363 from 479, we get 116.
Take the next digit (0) from the dividend and append it to 116, then repeat: 1160 / 121

Going ahead to step 8:
121 goes into 1160 9 times with a remainder of 71.
The next digit of our result is 9. 
Result so far: 392439.0
The remainder is 71 after subtracting 1089 from 1160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 9:
121 can be fit into 710 5 times, resulting in a remainder of 105.
Put 5 as the next digit of the answer. 
Result so far: 392439.5
Subtracting 605 from 710 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

On to step 10:
1050 divided by 121 is 8 with a remainder of 82.
Write down 8 as next digit of the result. 
Result so far: 392439.58
The remainder is 82 after subtracting 968 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 11:
The number 121 fits into 820 6 times, leaving a remainder of 94.
The next digit of our result is 6. 
Result so far: 392439.586
Deduct 726 from 820 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 12:
121 goes into 940 7 times with a remainder of 93.
Record the quotient 7 as the next digit in the result. 
Result so far: 392439.5867
The remainder is 93 after subtracting 847 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

On to step 13:
When dividing 930 by 121, we get 7 with a remainder of 83.
Record the quotient 7 as the next digit in the result. 
Result so far: 392439.58677
If we take 847 away from 930, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

The final outcome is 392439.58677, with a leftover of 8.3e-05.
