4385207 ÷ 122 
We want to figure out the number of times 4385207 can be divided by 122.

Moving on to step 1:
If we divide 4 by 122, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 122

On to step 2:
The number 122 fits into 43 0 times, leaving a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Grab the next digit (8) from the dividend, add it to 43, then carry on: 438 / 122

Moving on to step 3:
438 divided by 122 is 3 with a remainder of 72.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 366 from 438 leaves us with 72.
Append the next digit (5) from the dividend to 72 and continue with: 725 / 122

Advancing to step 4:
725 divided by 122 is 5 with a remainder of 115.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
The remainder is 115 after subtracting 610 from 725.
Bring next digit (2) of the dividend behind the 115 and repeat the process: 1152 / 122

Step 5:
122 goes into 1152 9 times with a remainder of 54.
The next digit of our result is 9. 
Result so far: 359.0
If we subtract 1098 from 1152, we get 54.
Bring next digit (0) of the dividend behind the 54 and repeat the process: 540 / 122

Going ahead to step 6:
If we divide 540 by 122, we get 4 and a remainder of 52.
The next digit of our result is 4. 
Result so far: 3594.0
Subtract 488 from 540 to get 52.
Take the next digit (7) from the dividend and append it to 52, then repeat: 527 / 122

Step 7:
122 can be fit into 527 4 times, resulting in a remainder of 39.
Put 4 as the next digit of the answer. 
Result so far: 35944.0
Deduct 488 from 527 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 8:
122 goes into 390 3 times with a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 35944.3
Subtracting 366 from 390 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 9:
If we divide 240 by 122, we get 1 and a remainder of 118.
The number 1 becomes the next digit in our result. 
Result so far: 35944.31
Subtract 122 from 240 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Step 10:
122 can be fit into 1180 9 times, resulting in a remainder of 82.
Write down 9 as next digit of the result. 
Result so far: 35944.319
If we take 1098 away from 1180, we end up 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.

Moving on to step 11:
The number 122 fits into 820 6 times, leaving a remainder of 88.
Record the quotient 6 as the next digit in the result. 
Result so far: 35944.3196
The remainder is 88 after subtracting 732 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 12:
If we divide 880 by 122, we get 7 and a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 35944.31967
Subtracting 854 from 880 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 13:
The number 122 fits into 260 2 times, leaving a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 35944.319672
If we take 244 away from 260, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 14:
When dividing 160 by 122, we get 1 with a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 35944.3196721
Subtract 122 from 160 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 15:
380 divided by 122 is 3 with a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 35944.31967213
Subtract 366 from 380 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 35944.31967213 with a remainder of 1.4e-08.
