87249145 ÷ 121 
We're looking to find how many times 121 goes into 87249145.

Going ahead to step 1:
The number 121 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 121

On to step 2:
If we divide 87 by 121, we get 0 and a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Include the next digit (2) from the dividend after 87, then repeat: 872 / 121

Going ahead to step 3:
The number 121 fits into 872 7 times, leaving a remainder of 25.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 847 from 872 leaves us with 25.
Take the next digit (4) from the dividend and append it to 25, then repeat: 254 / 121

Let's proceed to step 4:
121 can be fit into 254 2 times, resulting in a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 72.0
Deduct 242 from 254 and we're left with 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 121

Advancing to step 5:
When dividing 129 by 121, we get 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 721.0
Deduct 121 from 129 and we're left with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 121

Advancing to step 6:
The number 121 fits into 81 0 times, leaving a remainder of 81.
The next digit of our result is 0. 
Result so far: 7210.0
If we take 0 away from 81, we end up with 81.
Bring next digit (4) of the dividend behind the 81 and repeat the process: 814 / 121

Step 7:
When dividing 814 by 121, we get 6 with a remainder of 88.
The next digit of our result is 6. 
Result so far: 72106.0
Subtract 726 from 814 to get 88.
Append the next digit (5) from the dividend to 88 and continue with: 885 / 121

Let's proceed to step 8:
121 can be fit into 885 7 times, resulting in a remainder of 38.
The next digit of our result is 7. 
Result so far: 721067.0
Subtracting 847 from 885 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 9:
The number 121 fits into 380 3 times, leaving a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 721067.3
Deduct 363 from 380 and we're left 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.

Moving on to step 10:
121 can be fit into 170 1 times, resulting in a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 721067.31
If we subtract 121 from 170, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 11:
121 goes into 490 4 times with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 721067.314
Deduct 484 from 490 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 12:
121 goes into 60 0 times with a remainder of 60.
The next digit of our result is 0. 
Result so far: 721067.314
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 13:
When dividing 600 by 121, we get 4 with a remainder of 116.
The next digit of our result is 4. 
Result so far: 721067.31404
If we take 484 away from 600, we end up with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 14:
If we divide 1160 by 121, we get 9 and a remainder of 71.
Put 9 as the next digit of the answer. 
Result so far: 721067.314049
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.

Advancing to step 15:
121 can be fit into 710 5 times, resulting in a remainder of 105.
The next digit of our result is 5. 
Result so far: 721067.3140495
If we take 605 away from 710, we end up 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.

Step 16:
If we divide 1050 by 121, we get 8 and a remainder of 82.
The number 8 becomes the next digit in our result. 
Result so far: 721067.31404958
Deduct 968 from 1050 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

After the division, we end up with 721067.31404958 and a remainder of 8.2e-08.
