Let's divide 9193278 by 420
We want to figure out the number of times 9193278 can be divided by 420.

Advancing to step 1:
420 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 420

Let's proceed to step 2:
420 can be fit into 91 0 times, resulting in a remainder of 91.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Grab the next digit (9) from the dividend, add it to 91, then carry on: 919 / 420

Advancing to step 3:
420 can be fit into 919 2 times, resulting in a remainder of 79.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 79 after subtracting 840 from 919.
Include the next digit (3) from the dividend after 79, then repeat: 793 / 420

On to step 4:
If we divide 793 by 420, we get 1 and a remainder of 373.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Deduct 420 from 793 and we're left with 373.
Fetch the next digit (2) from the dividend, attach it to 373 and continue: 3732 / 420

Advancing to step 5:
The number 420 fits into 3732 8 times, leaving a remainder of 372.
Record the quotient 8 as the next digit in the result. 
Result so far: 218.0
Deduct 3360 from 3732 and we're left with 372.
Bring next digit (7) of the dividend behind the 372 and repeat the process: 3727 / 420

Going ahead to step 6:
If we divide 3727 by 420, we get 8 and a remainder of 367.
Write down 8 as next digit of the result. 
Result so far: 2188.0
Subtracting 3360 from 3727 leaves us with 367.
Fetch the next digit (8) from the dividend, attach it to 367 and continue: 3678 / 420

Advancing to step 7:
420 goes into 3678 8 times with a remainder of 318.
Put 8 as the next digit of the answer. 
Result so far: 21888.0
If we take 3360 away from 3678, we end up with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Going ahead to step 8:
420 can be fit into 3180 7 times, resulting in a remainder of 240.
Write down 7 as next digit of the result. 
Result so far: 21888.7
If we subtract 2940 from 3180, we get 240.
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 9:
If we divide 2400 by 420, we get 5 and a remainder of 300.
Write down 5 as next digit of the result. 
Result so far: 21888.75
Deduct 2100 from 2400 and we're left 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 10:
The number 420 fits into 3000 7 times, leaving a remainder of 60.
Write down 7 as next digit of the result. 
Result so far: 21888.757
Deduct 2940 from 3000 and we're left 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:
The number 420 fits into 600 1 times, leaving a remainder of 180.
Write down 1 as next digit of the result. 
Result so far: 21888.7571
If we take 420 away from 600, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 12:
If we divide 1800 by 420, we get 4 and a remainder of 120.
Record the quotient 4 as the next digit in the result. 
Result so far: 21888.75714
Subtract 1680 from 1800 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 13:
If we divide 1200 by 420, we get 2 and a remainder of 360.
The number 2 becomes the next digit in our result. 
Result so far: 21888.757142
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.

On to step 14:
When dividing 3600 by 420, we get 8 with a remainder of 240.
The number 8 becomes the next digit in our result. 
Result so far: 21888.7571428
Subtract 3360 from 3600 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 15:
420 goes into 2400 5 times with a remainder of 300.
The number 5 becomes the next digit in our result. 
Result so far: 21888.75714285
Subtracting 2100 from 2400 leaves us 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.

After the division, we end up with 21888.75714285 and a remainder of 3e-07.
