We're dividing 34074910 by 420 
We're looking to find how many times 420 goes into 34074910.

On to step 1:
420 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 420

Going ahead to step 2:
The number 420 fits into 34 0 times, leaving a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 34 and we're left with 34.
Take the next digit (0) from the dividend and append it to 34, then repeat: 340 / 420

Let's proceed to step 3:
420 goes into 340 0 times with a remainder of 340.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 340 after subtracting 0 from 340.
Take the next digit (7) from the dividend and append it to 340, then repeat: 3407 / 420

Moving on to step 4:
420 goes into 3407 8 times with a remainder of 47.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 3360 from 3407 leaves us with 47.
Append the next digit (4) from the dividend to 47 and continue with: 474 / 420

Let's proceed to step 5:
474 divided by 420 is 1 with a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 81.0
If we take 420 away from 474, we end up with 54.
Append the next digit (9) from the dividend to 54 and continue with: 549 / 420

Going ahead to step 6:
420 goes into 549 1 times with a remainder of 129.
The next digit of our result is 1. 
Result so far: 811.0
Subtracting 420 from 549 leaves us with 129.
Fetch the next digit (1) from the dividend, attach it to 129 and continue: 1291 / 420

Step 7:
When dividing 1291 by 420, we get 3 with a remainder of 31.
Use 3 as the next digit of our solution. 
Result so far: 8113.0
Subtract 1260 from 1291 to get 31.
Bring next digit (0) of the dividend behind the 31 and repeat the process: 310 / 420

Step 8:
310 divided by 420 is 0 with a remainder of 310.
Use 0 as the next digit of our solution. 
Result so far: 81130.0
The remainder is 310 after subtracting 0 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 9:
3100 divided by 420 is 7 with a remainder of 160.
Write down 7 as next digit of the result. 
Result so far: 81130.7
Deduct 2940 from 3100 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 10:
When dividing 1600 by 420, we get 3 with a remainder of 340.
The number 3 becomes the next digit in our result. 
Result so far: 81130.73
Subtract 1260 from 1600 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 11:
When dividing 3400 by 420, we get 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 81130.738
Subtract 3360 from 3400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
When dividing 400 by 420, we get 0 with a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 81130.738
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 13:
The number 420 fits into 4000 9 times, leaving a remainder of 220.
Write down 9 as next digit of the result. 
Result so far: 81130.73809
Subtracting 3780 from 4000 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 14:
2200 divided by 420 is 5 with a remainder of 100.
Write down 5 as next digit of the result. 
Result so far: 81130.738095
The remainder is 100 after subtracting 2100 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 15:
420 can be fit into 1000 2 times, resulting in a remainder of 160.
Record the quotient 2 as the next digit in the result. 
Result so far: 81130.7380952
Subtract 840 from 1000 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 16:
The number 420 fits into 1600 3 times, leaving a remainder of 340.
Use 3 as the next digit of our solution. 
Result so far: 81130.73809523
If we take 1260 away from 1600, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

The quotient of the division is 81130.73809523, and the remainder is 3.4e-07.
