6345216 ÷ 121 
We want to figure out the number of times 6345216 can be divided by 121.

Going ahead to step 1:
121 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 121

On to step 2:
When dividing 63 by 121, we get 0 with a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Grab the next digit (4) from the dividend, add it to 63, then carry on: 634 / 121

Step 3:
634 divided by 121 is 5 with a remainder of 29.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 605 from 634 and we're left with 29.
Append the next digit (5) from the dividend to 29 and continue with: 295 / 121

Advancing to step 4:
121 goes into 295 2 times with a remainder of 53.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
Subtract 242 from 295 to get 53.
Append the next digit (2) from the dividend to 53 and continue with: 532 / 121

Let's proceed to step 5:
121 can be fit into 532 4 times, resulting in a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 524.0
If we subtract 484 from 532, we get 48.
Bring next digit (1) of the dividend behind the 48 and repeat the process: 481 / 121

Advancing to step 6:
121 can be fit into 481 3 times, resulting in a remainder of 118.
Record the quotient 3 as the next digit in the result. 
Result so far: 5243.0
Subtract 363 from 481 to get 118.
Append the next digit (6) from the dividend to 118 and continue with: 1186 / 121

Advancing to step 7:
The number 121 fits into 1186 9 times, leaving a remainder of 97.
Use 9 as the next digit of our solution. 
Result so far: 52439.0
Subtracting 1089 from 1186 leaves us with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

On to step 8:
970 divided by 121 is 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 52439.8
Subtracting 968 from 970 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
121 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 52439.8
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
The number 121 fits into 200 1 times, leaving a remainder of 79.
Write down 1 as next digit of the result. 
Result so far: 52439.801
If we take 121 away from 200, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 11:
When dividing 790 by 121, we get 6 with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 52439.8016
If we subtract 726 from 790, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 12:
121 goes into 640 5 times with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 52439.80165
Subtracting 605 from 640 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 13:
121 can be fit into 350 2 times, resulting in a remainder of 108.
Write down 2 as next digit of the result. 
Result so far: 52439.801652
If we take 242 away from 350, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 14:
121 can be fit into 1080 8 times, resulting in a remainder of 112.
Put 8 as the next digit of the answer. 
Result so far: 52439.8016528
If we take 968 away from 1080, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 15:
121 goes into 1120 9 times with a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 52439.80165289
Subtract 1089 from 1120 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Our division results in 52439.80165289 with a remaining 3.1e-08.
