74870370 divided by 122 
Let's see how many times 122 fits into 74870370.

On to step 1:
If we divide 7 by 122, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 122

Moving on to step 2:
The number 122 fits into 74 0 times, leaving a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Take the next digit (8) from the dividend and append it to 74, then repeat: 748 / 122

Let's proceed to step 3:
When dividing 748 by 122, we get 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 16 after subtracting 732 from 748.
Take the next digit (7) from the dividend and append it to 16, then repeat: 167 / 122

On to step 4:
The number 122 fits into 167 1 times, leaving a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 61.0
Subtract 122 from 167 to get 45.
Fetch the next digit (0) from the dividend, attach it to 45 and continue: 450 / 122

Going ahead to step 5:
122 goes into 450 3 times with a remainder of 84.
Write down 3 as next digit of the result. 
Result so far: 613.0
If we subtract 366 from 450, we get 84.
Take the next digit (3) from the dividend and append it to 84, then repeat: 843 / 122

Advancing to step 6:
122 goes into 843 6 times with a remainder of 111.
Use 6 as the next digit of our solution. 
Result so far: 6136.0
If we take 732 away from 843, we end up with 111.
Include the next digit (7) from the dividend after 111, then repeat: 1117 / 122

Moving on to step 7:
When dividing 1117 by 122, we get 9 with a remainder of 19.
The next digit of our result is 9. 
Result so far: 61369.0
Deduct 1098 from 1117 and we're left with 19.
Include the next digit (0) from the dividend after 19, then repeat: 190 / 122

Going ahead to step 8:
122 can be fit into 190 1 times, resulting in a remainder of 68.
Record the quotient 1 as the next digit in the result. 
Result so far: 613691.0
Subtracting 122 from 190 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 9:
If we divide 680 by 122, we get 5 and a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 613691.5
Subtract 610 from 680 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.

On to step 10:
700 divided by 122 is 5 with a remainder of 90.
Use 5 as the next digit of our solution. 
Result so far: 613691.55
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.

The final outcome is 613691.55, with a leftover of 0.09.
