42526730 ÷ 121 
We want to figure out the number of times 42526730 can be divided by 121.

Let's proceed to step 1:
121 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 121

Step 2:
42 divided by 121 is 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Grab the next digit (5) from the dividend, add it to 42, then carry on: 425 / 121

Going ahead to step 3:
If we divide 425 by 121, we get 3 and a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 363 from 425 to get 62.
Append the next digit (2) from the dividend to 62 and continue with: 622 / 121

On to step 4:
121 goes into 622 5 times with a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
Subtracting 605 from 622 leaves us with 17.
Take the next digit (6) from the dividend and append it to 17, then repeat: 176 / 121

Step 5:
121 goes into 176 1 times with a remainder of 55.
Put 1 as the next digit of the answer. 
Result so far: 351.0
If we take 121 away from 176, we end up with 55.
Grab the next digit (7) from the dividend, add it to 55, then carry on: 557 / 121

Moving on to step 6:
If we divide 557 by 121, we get 4 and a remainder of 73.
The next digit of our result is 4. 
Result so far: 3514.0
If we take 484 away from 557, we end up with 73.
Bring next digit (3) of the dividend behind the 73 and repeat the process: 733 / 121

Step 7:
121 can be fit into 733 6 times, resulting in a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 35146.0
If we subtract 726 from 733, we get 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 121

Step 8:
When dividing 70 by 121, we get 0 with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 351460.0
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 9:
The number 121 fits into 700 5 times, leaving a remainder of 95.
Write down 5 as next digit of the result. 
Result so far: 351460.5
Deduct 605 from 700 and we're left with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Step 10:
950 divided by 121 is 7 with a remainder of 103.
The number 7 becomes the next digit in our result. 
Result so far: 351460.57
The remainder is 103 after subtracting 847 from 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Moving on to step 11:
When dividing 1030 by 121, we get 8 with a remainder of 62.
The number 8 becomes the next digit in our result. 
Result so far: 351460.578
Subtract 968 from 1030 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 12:
121 goes into 620 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 351460.5785
If we take 605 away from 620, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 13:
The number 121 fits into 150 1 times, leaving a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 351460.57851
Subtracting 121 from 150 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 14:
When dividing 290 by 121, we get 2 with a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 351460.578512
If we subtract 242 from 290, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 15:
When dividing 480 by 121, we get 3 with a remainder of 117.
The number 3 becomes the next digit in our result. 
Result so far: 351460.5785123
If we take 363 away from 480, we end up with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Moving on to step 16:
The number 121 fits into 1170 9 times, leaving a remainder of 81.
The number 9 becomes the next digit in our result. 
Result so far: 351460.57851239
If we take 1089 away from 1170, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

In conclusion, the division gives 351460.57851239 with a balance of 8.1e-08.
