We divide 7451958 by 21
Let's see how many times 21 fits into 7451958.

Step 1:
7 divided by 21 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 21

Let's proceed to step 2:
74 divided by 21 is 3 with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 63 from 74, we get 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 21

Let's proceed to step 3:
When dividing 115 by 21, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
Deduct 105 from 115 and we're left with 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 21

On to step 4:
21 can be fit into 101 4 times, resulting in a remainder of 17.
Write down 4 as next digit of the result. 
Result so far: 354.0
If we take 84 away from 101, we end up with 17.
Take the next digit (9) from the dividend and append it to 17, then repeat: 179 / 21

Let's proceed to step 5:
21 can be fit into 179 8 times, resulting in a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 3548.0
The remainder is 11 after subtracting 168 from 179.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 21

Advancing to step 6:
When dividing 115 by 21, we get 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 35485.0
Deduct 105 from 115 and we're left with 10.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 21

Let's proceed to step 7:
If we divide 108 by 21, we get 5 and a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 354855.0
If we subtract 105 from 108, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 8:
21 goes into 30 1 times with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 354855.1
Subtract 21 from 30 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 9:
The number 21 fits into 90 4 times, leaving a remainder of 6.
The next digit of our result is 4. 
Result so far: 354855.14
Subtract 84 from 90 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 10:
If we divide 60 by 21, we get 2 and a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 354855.142
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
21 can be fit into 180 8 times, resulting in a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 354855.1428
If we take 168 away from 180, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 12:
When dividing 120 by 21, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 354855.14285
The remainder is 15 after subtracting 105 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 13:
If we divide 150 by 21, we get 7 and a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 354855.142857
If we take 147 away from 150, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 14:
21 can be fit into 30 1 times, resulting in a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 354855.1428571
Deduct 21 from 30 and we're left 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.

Advancing to step 15:
When dividing 90 by 21, we get 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 354855.14285714
If we subtract 84 from 90, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 354855.14285714 with a remainder of 6e-09.
