37909573 ÷ 121 
We want to divide 37909573 by 121.

Going ahead to step 1:
121 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 121

Advancing to step 2:
When dividing 37 by 121, we get 0 with a remainder of 37.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 37 to get 37.
Fetch the next digit (9) from the dividend, attach it to 37 and continue: 379 / 121

Let's proceed to step 3:
The number 121 fits into 379 3 times, leaving a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 363 from 379 leaves us with 16.
Grab the next digit (0) from the dividend, add it to 16, then carry on: 160 / 121

On to step 4:
When dividing 160 by 121, we get 1 with a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
The remainder is 39 after subtracting 121 from 160.
Bring next digit (9) of the dividend behind the 39 and repeat the process: 399 / 121

Let's proceed to step 5:
399 divided by 121 is 3 with a remainder of 36.
Put 3 as the next digit of the answer. 
Result so far: 313.0
If we subtract 363 from 399, we get 36.
Grab the next digit (5) from the dividend, add it to 36, then carry on: 365 / 121

On to step 6:
121 can be fit into 365 3 times, resulting in a remainder of 2.
The next digit of our result is 3. 
Result so far: 3133.0
Subtracting 363 from 365 leaves us with 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 121

Step 7:
When dividing 27 by 121, we get 0 with a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 31330.0
If we subtract 0 from 27, we get 27.
Grab the next digit (3) from the dividend, add it to 27, then carry on: 273 / 121

Step 8:
If we divide 273 by 121, we get 2 and a remainder of 31.
Use 2 as the next digit of our solution. 
Result so far: 313302.0
Subtracting 242 from 273 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 9:
When dividing 310 by 121, we get 2 with a remainder of 68.
Put 2 as the next digit of the answer. 
Result so far: 313302.2
The remainder is 68 after subtracting 242 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 10:
121 goes into 680 5 times with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 313302.25
Deduct 605 from 680 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 11:
When dividing 750 by 121, we get 6 with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 313302.256
The remainder is 24 after subtracting 726 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 12:
121 can be fit into 240 1 times, resulting in a remainder of 119.
Write down 1 as next digit of the result. 
Result so far: 313302.2561
The remainder is 119 after subtracting 121 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Going ahead to step 13:
The number 121 fits into 1190 9 times, leaving a remainder of 101.
Write down 9 as next digit of the result. 
Result so far: 313302.25619
If we subtract 1089 from 1190, we get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

On to step 14:
1010 divided by 121 is 8 with a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 313302.256198
The remainder is 42 after subtracting 968 from 1010.
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 15:
The number 121 fits into 420 3 times, leaving a remainder of 57.
Record the quotient 3 as the next digit in the result. 
Result so far: 313302.2561983
The remainder is 57 after subtracting 363 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 16:
When dividing 570 by 121, we get 4 with a remainder of 86.
Write down 4 as next digit of the result. 
Result so far: 313302.25619834
If we subtract 484 from 570, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

The final outcome is 313302.25619834, with a leftover of 8.6e-08.
