We look at the division of 74982609 by 420 
We want to figure out the number of times 74982609 can be divided by 420.

Moving on to step 1:
When dividing 7 by 420, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 420

Let's proceed to step 2:
74 divided by 420 is 0 with a remainder of 74.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Append the next digit (9) from the dividend to 74 and continue with: 749 / 420

Moving on to step 3:
420 goes into 749 1 times with a remainder of 329.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 420 away from 749, we end up with 329.
Bring next digit (8) of the dividend behind the 329 and repeat the process: 3298 / 420

On to step 4:
420 can be fit into 3298 7 times, resulting in a remainder of 358.
The next digit of our result is 7. 
Result so far: 17.0
If we take 2940 away from 3298, we end up with 358.
Grab the next digit (2) from the dividend, add it to 358, then carry on: 3582 / 420

Moving on to step 5:
420 can be fit into 3582 8 times, resulting in a remainder of 222.
Use 8 as the next digit of our solution. 
Result so far: 178.0
If we subtract 3360 from 3582, we get 222.
Fetch the next digit (6) from the dividend, attach it to 222 and continue: 2226 / 420

Moving on to step 6:
2226 divided by 420 is 5 with a remainder of 126.
The next digit of our result is 5. 
Result so far: 1785.0
Deduct 2100 from 2226 and we're left with 126.
Grab the next digit (0) from the dividend, add it to 126, then carry on: 1260 / 420

Moving on to step 7:
When dividing 1260 by 420, we get 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 17853.0
If we take 1260 away from 1260, we end up with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 420

Let's proceed to step 8:
The number 420 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 178530.0
Subtracting 0 from 9 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
90 divided by 420 is 0 with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 178530.0
Deduct 0 from 90 and we're left 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.

Let's proceed to step 10:
420 can be fit into 900 2 times, resulting in a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 178530.02
Subtracting 840 from 900 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 11:
600 divided by 420 is 1 with a remainder of 180.
The next digit of our result is 1. 
Result so far: 178530.021
Subtract 420 from 600 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 12:
420 can be fit into 1800 4 times, resulting in a remainder of 120.
The next digit of our result is 4. 
Result so far: 178530.0214
Deduct 1680 from 1800 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 13:
420 goes into 1200 2 times with a remainder of 360.
Put 2 as the next digit of the answer. 
Result so far: 178530.02142
Subtract 840 from 1200 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 14:
3600 divided by 420 is 8 with a remainder of 240.
Use 8 as the next digit of our solution. 
Result so far: 178530.021428
The remainder is 240 after subtracting 3360 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 15:
420 goes into 2400 5 times with a remainder of 300.
Write down 5 as next digit of the result. 
Result so far: 178530.0214285
If we take 2100 away from 2400, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 16:
If we divide 3000 by 420, we get 7 and a remainder of 60.
The next digit of our result is 7. 
Result so far: 178530.02142857
If we subtract 2940 from 3000, 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.

The final outcome is 178530.02142857, with a leftover of 6e-08.
