We look at the division of 45651093 by 420 
Let's see how many times 420 fits into 45651093.

Step 1:
4 divided by 420 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 420

Advancing to step 2:
45 divided by 420 is 0 with a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Take the next digit (6) from the dividend and append it to 45, then repeat: 456 / 420

Moving on to step 3:
420 goes into 456 1 times with a remainder of 36.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 36 after subtracting 420 from 456.
Grab the next digit (5) from the dividend, add it to 36, then carry on: 365 / 420

Going ahead to step 4:
420 can be fit into 365 0 times, resulting in a remainder of 365.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 365 and we're left with 365.
Append the next digit (1) from the dividend to 365 and continue with: 3651 / 420

Moving on to step 5:
3651 divided by 420 is 8 with a remainder of 291.
The number 8 becomes the next digit in our result. 
Result so far: 108.0
Deduct 3360 from 3651 and we're left with 291.
Bring next digit (0) of the dividend behind the 291 and repeat the process: 2910 / 420

Let's proceed to step 6:
2910 divided by 420 is 6 with a remainder of 390.
The next digit of our result is 6. 
Result so far: 1086.0
Subtract 2520 from 2910 to get 390.
Append the next digit (9) from the dividend to 390 and continue with: 3909 / 420

Advancing to step 7:
3909 divided by 420 is 9 with a remainder of 129.
The number 9 becomes the next digit in our result. 
Result so far: 10869.0
The remainder is 129 after subtracting 3780 from 3909.
Fetch the next digit (3) from the dividend, attach it to 129 and continue: 1293 / 420

Moving on to step 8:
When dividing 1293 by 420, we get 3 with a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 108693.0
If we take 1260 away from 1293, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 9:
The number 420 fits into 330 0 times, leaving a remainder of 330.
The number 0 becomes the next digit in our result. 
Result so far: 108693.0
Subtract 0 from 330 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 10:
420 can be fit into 3300 7 times, resulting in a remainder of 360.
Write down 7 as next digit of the result. 
Result so far: 108693.07
The remainder is 360 after subtracting 2940 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 11:
When dividing 3600 by 420, we get 8 with a remainder of 240.
The next digit of our result is 8. 
Result so far: 108693.078
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 12:
420 goes into 2400 5 times with a remainder of 300.
Write down 5 as next digit of the result. 
Result so far: 108693.0785
Subtract 2100 from 2400 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 13:
420 goes into 3000 7 times with a remainder of 60.
Record the quotient 7 as the next digit in the result. 
Result so far: 108693.07857
If we take 2940 away from 3000, we end up 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.

Step 14:
The number 420 fits into 600 1 times, leaving a remainder of 180.
Put 1 as the next digit of the answer. 
Result so far: 108693.078571
The remainder is 180 after subtracting 420 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 15:
1800 divided by 420 is 4 with a remainder of 120.
The number 4 becomes the next digit in our result. 
Result so far: 108693.0785714
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.

On to step 16:
The number 420 fits into 1200 2 times, leaving a remainder of 360.
Put 2 as the next digit of the answer. 
Result so far: 108693.07857142
If we take 840 away from 1200, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

In conclusion, the division gives 108693.07857142 with a balance of 3.6e-07.
