We divide 42117945 by 122
We want to divide 42117945 by 122.

On to step 1:
If we divide 4 by 122, we get 0 and 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.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 122

On to step 2:
When dividing 42 by 122, we get 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Bring next digit (1) of the dividend behind the 42 and repeat the process: 421 / 122

Advancing to step 3:
The number 122 fits into 421 3 times, leaving a remainder of 55.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 55 after subtracting 366 from 421.
Append the next digit (1) from the dividend to 55 and continue with: 551 / 122

Step 4:
When dividing 551 by 122, we get 4 with a remainder of 63.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
Subtract 488 from 551 to get 63.
Include the next digit (7) from the dividend after 63, then repeat: 637 / 122

On to step 5:
637 divided by 122 is 5 with a remainder of 27.
Record the quotient 5 as the next digit in the result. 
Result so far: 345.0
Subtracting 610 from 637 leaves us with 27.
Take the next digit (9) from the dividend and append it to 27, then repeat: 279 / 122

Let's proceed to step 6:
122 can be fit into 279 2 times, resulting in a remainder of 35.
Use 2 as the next digit of our solution. 
Result so far: 3452.0
The remainder is 35 after subtracting 244 from 279.
Append the next digit (4) from the dividend to 35 and continue with: 354 / 122

On to step 7:
122 can be fit into 354 2 times, resulting in a remainder of 110.
Record the quotient 2 as the next digit in the result. 
Result so far: 34522.0
If we take 244 away from 354, we end up with 110.
Include the next digit (5) from the dividend after 110, then repeat: 1105 / 122

Going ahead to step 8:
122 can be fit into 1105 9 times, resulting in a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 345229.0
If we take 1098 away from 1105, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
If we divide 70 by 122, we get 0 and a remainder of 70.
The next digit of our result is 0. 
Result so far: 345229.0
Subtracting 0 from 70 leaves us with 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 10:
When dividing 700 by 122, we get 5 with a remainder of 90.
Write down 5 as next digit of the result. 
Result so far: 345229.05
If we take 610 away from 700, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 11:
900 divided by 122 is 7 with a remainder of 46.
The number 7 becomes the next digit in our result. 
Result so far: 345229.057
Subtracting 854 from 900 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 12:
122 can be fit into 460 3 times, resulting in a remainder of 94.
The number 3 becomes the next digit in our result. 
Result so far: 345229.0573
Subtract 366 from 460 to get 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 13:
122 goes into 940 7 times with a remainder of 86.
The next digit of our result is 7. 
Result so far: 345229.05737
If we take 854 away from 940, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 14:
122 can be fit into 860 7 times, resulting in a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 345229.057377
If we take 854 away from 860, we end up 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.

The final outcome is 345229.057377, with a leftover of 6e-07.
